The 6c Orange Transportation Stamp of the 1967-1973 Centennial Issue Part Three

Today's post finishes off the coverage for the 6c orange transportation design of this series, which was replaced by the 6c black of the same design in early 1970. Today, I will look at the booklet stamps, which came in both 25c booklets and $1.50 booklets, as well as the coil stamps.

The booklet stamps were all printed by the BABN, as were the sheet stamps. However the coil stamps were printed by the CBN, and if you look closely at the designs, you can see slight differences in the strength of engraving that are similar to the differences between dies 1 and 2 of the 6c black design.

These stamps are all relatively straightforward, with the exception of a few paper varieties that exist for both types of booklet stamps and the coils. Both the booklet and coil stamps are listed by Unitrade as existing on both dull fluorescent and hibrite papers. However, there are variations in both these paper types, that are not expressly discussed in Unitrade. The stamps from the 25c booklets also exist printed in fluorescent ink, as was the case with the perf. 10 sheet stamps.

The stamps from the booklets can easily be distinguished in cases where the side perforations have not been completely cut away, but the perforated edges on the outside edges of stamps from the $1.50 booklets, whereas these edges are always straight on stamps from the 25c booklets.

Paper Characteristics Other Than Fluorescence

The paper that was used to print the booklet panes from which these stamps come is generally a soft, horizontal wove paper. The paper is generally uncoated and has a smooth but porous surface. Unlike many of the sheet stamps, there is no surface ribbing visible on the paper. When held up to strong back lighting, there is a light vertical mesh pattern visible. The hibrite paper appears only very slightly off-white when viewed against a pure white background, whereas the other paper types appear to be a very deep cream off-white colour, when viewed against a stark white background.

Paper Fluorescence

Unitrade lists the booklet panes from which these stamps come as existing on papers with three different fluorescence levels:

  1. Dull fluorescent.
  2. Low fluorescent.
  3. Hibrite.
McCann lists the same three varieties of fluorescence, but also lists three more:

  1. Dull fluorescent with fluorescent fibres.
  2. Low fluorescent with fluorescent fibres, on panes with the fluorescent ink.
  3. Dead, or non-fluorescent. 
I do not have an example of the low fluorescent, without fluorescent fibres to show here. But I do have examples of all the other paper types, including two varieties of the dull fluorescent paper. The pictures below show examples of these various levels of fluorescence.

This first picture shows the stark difference between the hibrite paper and the dull fluorescent paper, with two dull fluorescent paper stamps shown on the top row, followed by five hibrite stamps on the bottom two rows. The hibrite paper on these stamps is a true hibrite and has a uniform, bluish white glow under UV light.

The next picture shows two of the dull fluorescent papers:

The stamp on the left is printed on a paper giving an ivory colour under UV. There are a very few (less than 5) low fluorescent fibres visible in the paper, but they are not generally noticeable to the eye. The stamp on the left is the dull fluorescent paper with fluorescent fibres, that McCann refers to in his booklet catalogue. The basic colour of the paper is violet grey, and then there is a very sparse concentration of low fluorescent fibres, very few medium fluorescent fibres and 1-2 high fluorescent fibres visible in the paper. They are noticeable if you view the stamp at close range, but if you are looking at the stamp from more than a few inches away, they are not very noticeable.  

The next picture shows a complete booklet pane of the dull fluorescent greyish paper, shown next to the ivory paper:

This paper contains a few low fluorescent fibres, but they are not evenly distributed, so that some stamps show no fibres at all, while others might show one fibre.

The next picture shows an example of the so called dead paper.

As you can see, this paper is a deep grey under the UV light. The difference is more readily visible if you look at the colour of the label and compare it to the stamp on the right. There are no fluorescent fibres in this paper. This paper is, in my opinion, what McCann means when he refers  to "dead" paper. It is clearly deeper in colour than the normal dull fluorescent paper, but it is not as deep as many of the non-fluorescent papers found on other stamps of the series.

Lastly, we have the low fluorescent paper, with fluorescent fibres, shown in the picture below:

Although the paper of this booklet pane does not appear very bright, you can see that it is much brighter than the dull fluorescent paper. This paper contains a considerable amount of fluorescent fibres, and you can see them most easily in the label at the top of the booklet. The fibres included in this paper cover the full range of fluorescence and include:

  1. A low density concentration of low fluorescent fibres.
  2. A very sparse concentration of medium and high fluorescent fibres.
  3. Very few hibrite fibres. 


Unitrade does not list any specific shade varieties on this stamp. However, they do list a fluorescent orange ink, similar to that found on selected printings of the perf. 10 sheet stamps. McCann goes a little bit deeper than Unitrade and distinguishes between a fluorescent orange ink, which it says exists on dull fluorescent, low fluorescent and LF-fl paper, and a fluorescent red ink, which is generally only found on the dull fluorescent paper. Both of these inks are transformative in the sense that their colour appears radically different under the UV light, as compared to normal light. I do not have examples of either of these that I can show here at the moment, but I will add some when I come across them.

I have found two very closely related shades of these booklet stamps as shown below:

Both of these shades are closest to orange-red on the Gibbons colour key, with the shade on the right being a little brighter than the shade on the left.

Under UV light, many of the inks retain their basic orange-red colour, or go a bit deeper than they appear under white light. However, there are some inks, particularly on many of the hibrite paper printings that appear black under UV. These later inks are transformative in nature, while the others are non-transformative.


On these booklet stamps, I have found three types of dextrose gum:

  1. A cream gum that is smooth, has a satin sheen, and shows a very fine pattern of diagonal cracks running across it. 
  2. A colourless gum that is smooth, and has a semi-gloss sheen.
  3. A colourless gum that is smooth, and has a glossy sheen, and shows what almost appear to be horizontal brush strokes running across it. 

I took some pictures of these types under my desk lamp to attempt to show these differences more clearly:

This picture shows the crackly gum on the top stamp, and the glossy gum on the bottom stamp. Hopefully you can see the difference in sheen and general appearance between these two types of gum

Here is a comparison of the high gloss gum and the semi-gloss gum. The high gloss is shown on the bottom stamp, while the semi-gloss is shown on the top stamp.


Unitrade lists the perforation as being comb 10.0. However, McCann notes that the exact perforation is 9.9 comb.

Plate Flaws

I would expect that these booklets should exist with at least some of the 100+ minor constant flaws that are reported to exist on the sheet stamps. Such flaws are generally small specks of colour in areas of the design where there shouldn't be any. I will add images of the more prominent ones as I come across them.

Paper Characteristics Other Than Fluorescence

The paper used to print the booklet panes from which these stamps come exhibits very similar characteristics to the paper used to print the 25c booklet panes, with a few differences:

  1. The paper is always horizontal wove.
  2. It has a very light surface coating, and a smooth printing surface, which keeps loose fibres from forming on the paper surface.
  3. It is a light cream colour when viewed against a stark white background. 
  4. No mesh pattern is visible when the paper is viewed against strong back lighting

Paper Fluorescence

Unitrade lists the booklet panes from which these stamps come as existing on non-fluorescent paper, and low fluorescent paper with fluorescent fibres. McCann lists both a dull fluorescent paper and a dead paper, as well as dull with fluorescent fibres, low fluorescent and high fluorescent. So there are clearly more varieties of fluorescence than Unitrade lists.

I do not have an example of either the dead paper, the dull paper with fluorescent fibres, or the high fluorescent paper to show at the moment. However, I will add examples when they become available. However, I do have the dull fluorescent paper, as well as the low fluorescent paper with fluorescent fibres, which are shown in the picture below:

The booklet on the right is the dull fluorescent paper, which has a greyish colour under the UV light, and shows no fluorescent fibres in the paper. The booklet on the left is a low fluorescent paper that contains sparse concentrations of low and medium fluorescent fibres, and a very sparse concentration of high fluorescent fibres.


I have found two shades of orange red ink on these stamps. Generally, the shade is a deep bright orange red, but a slightly duller version is often seen. The scan below shows both these shades:

The deep bright orange red is shown on the left stamp, and the right stamp shows a slightly duller version of the same shade. Under UV light, the shades appear more or less similar to how they appear under white light, only deeper. Therefore they are non-transformative inks.


The gum types found on these stamps are similar to those found on the 25c booklet stamps, with one exception: I have not found an example of this booklet with the high gloss gum. However the crackly gum and the semi-gloss gum have been noted on these panes, and likely exist with all the levels of  paper fluorescence discussed.


Unitrade lists the perforation as comb 10.0, however McCann states that it is actually 9.9 comb, as was the case with the 25c booklets.

The perforations of these booklets are different from other booklets issued up to this point in one important respect: the left and right edges of the panes were not left imperforate prior to be guillotined. Instead they were perforated, so that most stamps from the sides of these booklets will have perforations on all sides. However, the perforations on one side will be uniform and obviously cut, which will enable you to positively identify singles as having come from these booklets.

The scan below shows three singles from a typical booklet, two from the right side of the booklet, and one from the left, showing the guillotined perforations:

The left stamp is from the lower right corner of the booklet, as evidenced by the straight edge and the straight perforations on the right. Notice how the perforations on this side are perfectly uniform, with no fibres protruding from the perforation tips. The stamp in the middle has these perforations on the left side, which indicates that it comes from the left side of one of rows 2 thorough 9. Finally, the stamp on the right is from the right side of the booklet, of one of rows 1-9. In some instances, the guilotining will have been done poorly, resulting in clipped or missing perforations. But in most cases, remnants of these perforations will still be visible. I have yet to see a stamp from these booklets that has full size margins with completely straight edges at the sides.

Plate Flaws

McCann lists these booklets as existing with a mole on the lip or nose of the Queen on the first stamp of the 9th horizontal row. As we shall see in subsequent posts, this is a semi-constant flaw that is found on the 6c black booklets as well. I say that it is semi-constant because not every booklet is affected.

My comments about the constant plate flaws on sheet stamps, existing on the booklets, for the 25c booklets above applies here too. I do not know, which of the flaws found on the sheet stamps exist here as well. I simply have to add images and document what exists as I find them.

Coil Stamps - Unitrade #468A and #468Ai

The coil stamps of this design marked a new era in Canadian coil stamp production. Previously, the coils were produced in rolls of 500 stamps each that began with 10 blank labels and ended with 10 blank labels. The rolls themselves had been prepared by joining large strips of stamps together, which in turn had been cut from large, perforated sheets of stamps. Each roll was produced separately and enclosed in brown paper that had the denomination handstamped on the wrapping paper in purple.

These new coils were now produced in rolls of 100 that were also wrapped in paper, but instead of being produced individually, the rolls were produced in sticks of 10 rolls, which were produced by taking a 10 x 100 roll of stamps, that was perforated in the horizontal direction only, wrapping it in paper as before, and then scoring it between the rolls. The rolls could then be snapped apart and sold. They were designed to be stored in little plastic stamp dispensers, so that a user could tear one stamp off the roll. As such, they do not contain any joins, and jumps are much, much more difficult to spot, because they are so small compared to earlier coil issues, where the jumps in spacing are more obvious.

Paper Characteristics Other Than Fluorescence

Like the previous coil stamps of this series, these coil stamps can be found on both horizontally and vertically wove paper. The differences can be readily seen in the way that the mint stamps curl when left exposed to the air, as the picture below shows:

The strip on the left of this picture is clearly curling upward, which indicates that the weave direction of the paper is horizontal. In contrast, the pair on the right is lying flat. In actuality the paper of this pair bends more easily in the vertical direction than it does in the horizontal direction. This indicates that the paper is vertical wove paper.

I have not seen any other variation in the physical characteristics of the paper. It is a very lightly coated paper that has a smooth, semi-porous surface. There is often, but not always a very light ribbing present on the gum side of stamps that mimics the horizontal mesh pattern of the paper. This pattern is always very clearly visible when the stamps are viewed against very strong back lighting.

Paper Fluorescence

Unitrade lists these coil stamps as existing on either dull fluorescent paper, or hibrite paper. In reality, the so called hibrite paper varies from a high fluorescent paper to a true hibrite, while the dull fluorescent paper also shows variations. Neither of these types of variations are mentioned or listed in Unitrade. The pictures below show some of these variations.

Let's start with the hibrite papers:

All of the stamps in this picture are considered by Unitrade to be hibrite. However, the pair in the right is clearly brighter than the other stamps, and is more in line with what we would typically expect true hibrite paper to look like. The other stamps are on what I would consider to be on high fluorescent, or very bright medium fluorescent paper. On these papers, some hibrite fibres are ocasionally visible in the paper, whereas they are not on the true hibrite paper. 

Now, turning to the dull fluorescent papers, there are actually three papers that have a deeper, duller appearance than the standard dull fluorescent papers. They are actually very close to dead paper, and usually have some fluorescent fibres visible in the paper, but very, very few. They vary in colour under the UV light from a distinct violet grey, to grey, to a greyish white. The pictures below show these paper types:

This is the violet-grey paper that contains very few high fluorescent and hibrite fibres in the paper. 

On the right we have the grey paper and on the left the greyish white paper. On these two papers there are very few medium fluorescent and very few high fluorescent fibres. There are no hibrite fibres in either of these papers.

Then we have the dull fluorescent papers. Again, I have found that there are at least three different dull fluorescent papers for this stamp, that appear a different colour under under the UV lamp. These papers are characterized by the almost complete absence of any fluorescent fibres. There are maybe 1 or 2 medium fluorescent fibres on a stamp, but that's it. You can't generally see them unless you are looking for them specifically. The picture below shows the three types of dull fluorescent paper that I have found:

The left hand strip is the grey paper. The pair in the middle is still grey, but with a distinct yellowish cream tone and the stamp on the right is greyish white. 


These coil stamps display a somewhat disappointing uniformity of colour. Nevertheless, I have found two distinct shades of orange on them. Both completely lack the dominant reddish undertone that one tends to see on the BABN stamps. The two shades are shown in the scan below:

The shade most commonly seen on these stamps is shown on the strip on the left. It is almost a perfect match to Gibbons' orange red. The strip on the right is a much lighter and brighter shade, and is closest to bright orange on the Gibbons key. This shade is much less often seen than the orange red. 

Under UV light some of these inks change colour and become very deep red oranges, and other times the colours look more or less the same as they do in normal light. However, in nearly all cases, except for a few printings on hibrite paper, the basic colour still looks like a variation of orange red. Those few printings on hibrite paper, look black under UV light. Therefore, all of the inks used to print these coils are non-transformative, except for a few printings on the hibrite paper, which are transformative. 


I have found three different types of dextrose gum on these coils:

  1. A completely smooth and even yellowish cream gum that has a semi-gloss sheen.
  2. A somewhat streaky yellowish cream gum that has a semi-gloss sheen. 
  3. A blotchy gum that has a satin sheen.
The smooth and slightly streaky gums are the same as those that we see on all CBN stamps of this series prior to 1970. The blotchy gum is first seen on very late printings of the 1c and 5c sheet stamps, and is known to originate sometime in 1970. So, it would follow that this type of gum on these coil stamps likely identifies it as having come from the last printings made of these coil stamps, just before they were replaced in August 1970.

I took some pictures under my desk lamp of the three gum types, and I hope they will adequately illustrate the different types:

Here is the smooth gum. As you can see, it is more or less evenly applied across the stamps. There may be the odd shallow area here and there, but it is not regular enough for the gum to be considered streaky.

Let's take a look at the slightly streaky gum:

The shot is out of focus for some reason, and despite several takes, I could not get a clearer picture than this. However, this should be sufficient in that you can see several areas of unevenness in the application of the gum that run from top to bottom across the stamp. It is this pattern that makes the gum slightly streaky.

Lastly, let's take a look at the very distinct blotchy gum:

This picture shows the extreme blotchy appearance of this gum type.


Unlike the previous 3c, 4c and 5c coil stamps printed by the CBN, which were perforated 9.5 horizontally, these stamps are perforated 10 horizontally.  Occasionally, you can find strips in which one or more of the horizontal perforations are completely missing, due to a missing or broken pin in the perforating wheel. The scan below shows an example of a missing perforation that occurred on one stamp in a strip of 4:

On this stamp, the perforation at the top right is completely missing.

Plate Flaws

Unitrade does not list any plate flaws at all on these stamps, and I cannot recall seeing any in my 30 years of handling the stamps of this issue. However, I have come across examples that show ink smudges in the margins between stamps, such as the one shown below:

On this stamp, there is a relatively large smudge of orange ink in the top margin, above "postes".

Spacing Varieties and Jumps

As is the case with all coil stamps printed by CBN, these coil stamps exist with the usual range of wide and narrow spacing varieties between the stamps. The normal spacing between stamp impressions is approximately 4 mm, but narrow spacings under 3 mm can be found, and wide spacings over 4.5 mm can also be found. However, in addition to these usual spacing varieties Unitrade notes that an exceptionally wide spacing variety exists, in which the space is 17 mm. It notes that the gap is actually a gutter, an fewer than 10 of these "gutter strips" exist.

A typical wide spacing variety is shown in the scan below:

The normal 4 mm spacing between stamps is shown on the left strip. On the right strip between the two middle stamps is a clear 5 mm wide space. This is considered to be wide spacing. One word of caution when looking for wide spacing strips: off centre strips in which the perforations are very close to one stamp will appear to have wider spacing than they actually have. So to properly identify them, you actually have the measure the space. 


This is the first of the modern coil stamps printed by the CBN to be listed by Unitrade as existing in entirely imperforate form. As far as the imperforate pairs of this issue go, it is the least scarce, listing for $400 in Unitrade for a pair on dull fluorescent paper. A pair on hibrite paper is much scarcer, listing for 10 times as much as this.

This brings us to the end of the 6c orange transportation stamp. Next week, I will begin to examine the printings of the 6c black.

An Important Announcement:

After nearly a year of development, the Brixton-Chrome Website is now live, with 300 or so stamp listings from the 1917 Confederation Issue through the 1928 Scroll Issue. I decided to bring it online sooner, rather than later, so that I could obtain feedback from customers as I develop it and move toward the July 31, 2018 grand opening. So, please feel free to go on there and get acquainted with the layout. Paypal is working now, and I expect to add credit card payments in the next week or so, once I get approval from Paypal.

You can visit the website by clicking on the following link:

Feedback received so far this first week from customers has been extremely positive. Most have commented on the ease with which they can browse listings without having to use the search function. Unlike most stamp websites, you can browse by:
  1. Catalogue number
  2. Issue
  3. Item type, i.e. single stamps, plate blocks, booklets, covers, first day covers and cancellations.
  4. Condition and grade, i.e, mint and used, as well as the major condition grades.
  5. Price range - our stamps are organized into 8 price ranges, from under $1 to over $250.
The base currency of the listings is US dollars because the software that drives the site is hosted out of California. However, there is a currency translation feature that allows you to select a display currency for all the prices that you see as you shop. 

My inventory that is currently running live in E-bay will be transferred over to the site over the next 10-12 weeks. 1,500 or so items that were created on E-bay, and that cannot be easily transferred over, will be placed on sale at 25% off the normal prices until July 31, 2018, after which time they will be listed on the website as new listings. If you wish to shop for these stamps, you may access the listings by clicking on the following link:

The issues that will be on sale are generally all issues up to the end of the Admiral issue in 1926, and the Karsh and Wilding Issues from 1953-1962.

By far the most exciting aspect to shopping on the website will be the discounts. We give discounts ranging between 5% and 20% on all orders over $10 USD. Customers who register an account with us prior to July 31, 2018, will qualify for a special discount regime, in which they receive an additional 5% off at every level of discount offered, FOREVER. This means that every single order will be discounted by anywhere from 5% to 25%!

To become a registered Brixton-Chrome customer, simply go to the login page from one of the menus located on the home page, at the top, right side or bottom of the page, and follow the instructions. You will need to enter your e-mail address and select a password.

I look forward to your feedback. I plan to gather up all feedback received over the next few months, and engage a professional programmer to assist me to make any required cosmetic and functional changes that customers have indicated would enhance their shopping experience.

Happy stamping everyone!


  1. Looking at this issue generally, I obtained an accumulation of these some time ago, and have put them aside as being too complex until I found your blog.

    First of all I am in the UK and the best reference I can find is trhe old SG "Elizabethan" catalogue ( 1979 edition ) which covers the basics very well.

    Secondly my accumulation is all ( soaked) postally used so there will no doubt be issues with envelope contamination.

    Thirdly I use both long wave and short wave uv lights and have noticed that 2 stamps which react identically with one light often react differently with the other - particularly the flourescence difference. Can you throw any light (groan!) on that ?

    Unfortunately I have a quite small sample, and I am unsure as how to how to seperate them without a large control collection. I have already decided that to get any meaningful results each value ( except multi- value booklets have to be treated completely seperately.

    Any comments you can make will be greatfully received.

    1. Hi Malcolm.

      First of all, I would like to welcome you as a new reader! I hope you will find all the information you are looking for here. It is my vision to produce the best online resource for Canadian philatelists seeking to learn more about their stamps.

      This issue is indeed a very complex one. This post you just read was the 40th consecutive one that I have published on the series, and I still have 10 values of the set left to go. So lots more information to come.

      Envelope contamination can be a problem, but with experience, it is generally easy to spot:

      1. Stamps that are hibrite on the back, but dull on the front are generally contaminated, as there are no extant mint stamps that show these combinations of fluorescence.

      2. Stamps that show mottled fluorescence on either the front or back or significant differences between the fluorescence on the front and back are generally contaminated, at least for this issue. Later, with the 1972-78 issue, there are legitimate differences between the fluorescence on the front and back of stamps, but not generally until after 1971.

      I admit that I have never used a shortwave lamp to study these because it generally does not work with the Ottawa tagging or the Winnipeg tagging in the same way that it works on GB phosphors. I do not doubt that one could probably do a completely parallel study of papers and inks using these, but I haven't gone that far (yet). I use a long wave black light that is 18 inches long, that can be purchased from any large housewares shop for $30 CDN.

      My posts are designed so that you can learn to sort the different papers and identify the different levels of fluorescence using my posts and the pictures in them. I understand that my pictures do not always do as good a job of showing the true appearance of the varieties, but my hope is that the pictures coupled with the descriptions and my system of nomenclature for describing papers will give philatelists the tools they need to study these fascinating stamps, without having to begin with a reference collection.

      My suggestion is to start with my post about studying paper fluorescence on modern Canadian stamps. If you search for this title in the search bar, you should find the post. Then, take a look at my posts on the papers used to print the centennial issue stamps and the study of fluorescence on the 1967-73 Centennial issue - they are near the beginning of this series. These should give you a general understanding of what to look for, and then my individual posts on each value of the series, will help you do final sorts. In a lot of cases, I give you an algorithm for efficiently sorting large quantities of used and mint stamps.

      I hope this all helps. Sorry for my verbosity. It's what I do.

    2. Thanks for that. I have found that the sw lamp accentuates the differences in whiteness of the paper, but the "ottawa" phosphor shows the same. It also produces an "afterglow" on the Winnipeg phosphor after switching off the light ( I only have one of these ). I got into using both lamps whilst studying GB Machins, and a combination of both lamps plus natural daylight helps to get into the minutiae.

      The best way to discover differences I think is by comparison with a positively identified example. However flourescence is a bit like shades - there are ones which can be identified and then there are ones that fall in between which are difficult to pin down as one or the other.

      I think I am going to have to take them all out again and using your blog go through them. I think the first thing is to work out a schematic method to eliminate definite duplicates and also put together control copies to compare any new additions against.

      I almost wish I hadn't found this site as I am going to develop brain ache to rival Machin study!!

    3. My pleasure Malcolm. I think if you can deal with the complexity of the Machin Heads, then you can deal with anything. This is complex, sure, but nowhere near as much as the Machins.

      The most difficult aspect to fluorescence on paper is recognizing the difference between the ambient fluorescence in the overall paper, and fluorescence imparted by different concentrations of fluorescent fibres or varying brightness that are embedded in the paper. This accounts for many of those "in between" instances, if you have a good 10x power loupe, you can see the different concentrations of fibres and their brightness. Trying to study Canadian stamp paper without this is like trying to study QV Perkins Bacon issues without a perforation gauge, or a watermark tray.

    4. Firstly many thanks for doing these posts. You mention the how the sheets (600) were guillotined into panes of 100. Singles from booklets are mentioned by Unitrade and dealers, but how do you tell a booklet single with a straight edge from those in the sheets. A straight top edge is from a sheet; a guillotined perf. (l or r) is from booklet pane 459a, otherwise… Peter

    5. Hi Peter,

      Firstly, it is my pleasure to do these posts. Assisting collectors like yourself is the reason why I became a stamp dealer in the first place.

      Identification is indeed tricky, but with patience, most can be.

      Lets start with the perf 12.5 x12. This is the easiest because it was not issued in booklet form. All booklets containing the 6c orange are perf. 10.

      Turning to these, there were two layouts. The 25c booklets and $1.50 booklets.

      The $1.50 booklets are easy because there is only 1 straight edge at the bottom, and the guillotined perfs at the sides. The middle stamp though can be confused with a stamp from the bottom row of a guillotined pane. However, if it is on the low fluorescent paper, it can generally be identified as having come from the booklet. While there is also a low fluorescent sheet stamp, it does not contain the same dense concentration of fluorescent fibres that the booklet stamp does. Similarly, any high fluorescent stamp must be from the booklet. Clearly the tricky case is the dull fluorescent paper, where the booklet stamps and sheet stamps become very difficult to distinguish. I am sure that there is probably a way to tell them apart, but I am not sure how.

      Then there is the 25c booklets. These have a block of 4 stamps at the bottom of the pane, so that 2 stamps have one straight edge at left or right and two straight edges at the corners. You would be right to observe that these are the same as guillotined sheet stamps.

      Again it becomes necessary to turn to paper. Any hibrite stamp must be from a booklet, as the sheets are not known to exist HB. The dead paper also likely comes from a booklet.

      That leaves the dull fluorescent and low fluorescent papers which are hard to distinguish. In the end, it may come down to careful comparison of shades, or plate characteristics, but at the moment, I do not know for sure how to tell booklet stamps and sheet stamps on the same paper type apart.

  2. Many thanks for such a quick and thorough reply. Yes the HB is the easy and fortunate delineating characteristic. At present I do not have enough specimens to go too much further. But, but how can Unitrade list booklet singles so 'simply'? And not just for 459 but starting with the Admirals. As a kid I stashed the straight edges and corners (especially the Centennials) not knowing what they mean. But even today without info (including sheet layouts and cutting) like yours we can be left with a false sense of having a booklet single. And for the 459 left and right straight edges, the number from sheets and from the 25 cent booklet are fairly equal (21M).

    1. Unitrade is not anywhere near being up to par in my opinion, compared to other specialized catalogues from around the world. Compare it to The Stanley Gibbons specialized catalogues for Great Britain, ot Michel for Germany, Facit for Scandinavia, Campbell Patterson for New Zealand, or Brusden White for Australia, and you can see a huge difference in the amount of coverage given to specialized detail.

      They are much better than they used to be: booklet singles weren't even listed at all until about 1990.

      But there are a lot of instances where Unitrade insists that it is impossible to distinguish between certain printings of modern stamps. My take is that they are usually incorrect: they can be distinguished, but not easily. Philately, in my opinion is not always about ease and simplicity. Sometimes it takes careful study and patience to unravel the story of a particular stamp, and to me, that is what the hobby is all about.

  3. I agree as well. Lots of interesting info here on Canadian stamps. I also agree that the most beautiful stamps came out between 1927-1946!

    I was especially interested in the 6¢ orange issue. I specialized in the Centennial's & started collecting when Canada Post was divesting itself of this series.

    One stamp I was looking for here, but did not see is the fluorescent overprint of "9959" (or 5959?). I bought a copy long, long ago & wanted to compare it to what you would have. I'm still looking for someone's copy to compare mine to. Going by the looks of mine, I'd say it is faked. But i don't really know for sure. Do you have any info on this stamp?

    1. I did write about that stamp here, or at least I thought I did. I may only have mentioned it when I wrote about the 5c. I have never seen this stamp before, and would love to have a scan to see how it looks. I am curious to know why you think yours is fake?

  4. I feel so happy writing this review about Wizard Charles. You can as well hire him today!
