The 10c Jack Pine Stamp of the 1967-73 Centennial Issue Part One
In dealing with this value, rather than deal with all the untagged stamps first and then the tagged, I am going to split this value by the type of gum. So, today's post will examine the stamps with dextrose gum, then next week, I will look at the stamps with the spotty white gum, and then finally the following week, I will look at the stamps issued with PVA gum, in each case dealing with the tagging types and varieties that exist.
Unitrade's listings for the dextrose gum stamps are fairly simple. They now list three paper types for the untagged stamps and none at all for the Winnipeg Tagged stamps. But, as we shall see, there are far more collectible varieties to this stamp than Unitrade lists, including shade variations, paper fluorescence variations not listed, perforation variations and gum variations.
According to Unitrade, the dextrose gum stamps were first released with the basic set on February 8, 1967, and were in use until the stamps with spotty white gum appeared in December 1971. The Winnipeg tagged stamps were not issued until December 9, 1969.
Paper Characteristics Other Than Fluorescence
In addition to the paper fluorescence, there are other differences between the various papers that were used to print these stamps. The main differences are in the direction of the paper weave, as determined by which direction the paper bends most easily, whether or not any mesh pattern or ribbing is visible, the surface porosity of the paper, as seen under magnification, and how the paper appears when viewed against strong back-lighting.
I have noted the following paper types, ignoring the fluorescence:
- A cream coloured vertical wove paper that appears to have a distinct multi-directional weave pattern, that nonetheless appears predominantly vertical when stamps and blocks are held up to a strong back light. Under magnification the paper has a smooth, finished surface, with no loose fibres and no visible porosity. On this paper, you can usually see some of the mesh pattern through the gum.
- A similar paper to #1 above, except that the mesh pattern appears predominantly horizontal when viewed against strong back light.
- A whiter, horizontal wove paper, that shows very light vertical ribbing through the gum, and a clear vertical mesh pattern when viewed through back lighting. This paper has a clear surface coating, no loose fibres or porosity on the surface.
- A cream coloured vertical wove paper that shows no ribbing at all, and no mesh pattern whatsoever, even when viewed against strong back lighting. The surface is lightly coated, but there is still some surface porosity visible under magnification.
- A thinner, whiter cream and vertical wove paper that again shows no ribbing on either the front, or the back. The design is clearly visible through the back, and when held up to strong back lighting, a mesh pattern that is both horizontal and vertical can be seen. The paper has a light surface coating that prevents loose fibres and surface porosity.
- A cream coloured horizontal wove paper that has a distinct horizontal mesh pattern when viewed against strong back lighting. The printing surface is lightly coated and no loose fibres are visible on the surface/
Unitrade lists three levels of fluorescence for the untagged stamps:
- Dull fluorescent
- Non-fluorescent flecked
In this first picture we have a variation of the dull fluorescent paper on the left, and a variation of the non-fluorescent paper on the right. Notice how much brighter the dull fluorescent paper appears when placed next to the non-fluorescent. The non-fluorescent paper is very dark, appearing violet grey in this case. It can also be deep brown or deep violet. But, in all cases, it reflects very little if any white light.
The next picture shows the difference between the low fluorescent paper and the dull fluorescent paper:
Low Fluorescent Papers
In studying this stamp, I have found five varieties of fluorescence that are definitely brighter than dull and can best be described as low fluorescence. All of these papers are flecked to a degree. Interestingly, three of these occur on the Winnipeg tagged stamps. The pictures below show these papers:
The top stamps appear low fluorescent bluish grey under UV. The left stamp contains very sparse concentrations of low, medium and high fluorescent fibres. The block appears low fluorescent greyish under UV and contains very few medium fluorescent fibres.
There is a low fluorescent paper that does not appear to contain any fluorescent fibres. The stamp below is an example:
This stamp appears low fluorescent greyish white under UV.
Dull Fluorescent Papers
There exists a staggering variety of dull fluorescent papers. The first six of these are all very dull, being close to non-fluorescent. They all contain varying concentrations of fluorescent fibres, which are not high. These may indeed be what Unitrade classifies as NF-fl paper.
These first two blocks appear a dull fluorescent greyish colour with a yellowish undertone under UV - not quite as dark as they appear in the picture above. The block on the left contains very few medium fluorescent fibres, while the one on the right contains very few low, medium, high fluorescent and hibrite fibres. You can just see the brighter of these if you concentrate in the area of the selvage between the inscription and the word "Canada" of the lower left stamp in the block.
The block on the left is a dull fluorescent yellowish grey under UV and contains only 1-2 medium fluorescent fibres on each stamp in the block. The one on the right is more of a pure grey colour under UV and contains very few medium and high fluorescent fibres.
The remaining variations of the dull fluorescent paper are all much less greyish and further away from the colours normally associated with non-fluorescent paper.
This paper is dull fluorescent bluish white under UV and does not contain any fluorescent fibres.
There is a very wide range of shades on this stamp, from brown olives, all the way to deep yellow greens. The colour is generally a blend of green, grey, brown and yellow. so that all the shades will result from variation in the concentrations of these component hues. Generally speaking, the earlier printings with dextrose gum tend to contain more grey and more brown in the green, while the later PVA gum printings tend to contain more yellow, more green and less of both the brown and grey.
Here are two very similar shades of olive green: the pure olive green, as shown on the Gibbons colour key, and the deep olive:
The next scan shows the difference between the pure olive green shade and a slightly less deep version of the deep olive, as shown in the Gibbons colour key:
The next shade is the pure grey olive shade, as shown on the Gibbons colour key. I have juxtaposed a block printed in this shade, with the deep olive shade above:
The deep olive is shown on the left, while the grey olive is shown on the right.
The next shade is a slightly paler version of the grey olive:
A deep yellow green shade also exists that is a very close match to the deep yellow green on the Gibbons colour key. The scan below shows this shade next to the pale grey olive:
Last, but by no means least, there is the bronze green shade:
- Sage green, which is not often seen will be very pale and will contain the most grey. It will not contain any brown undertone.
- Brown olive will contain more brown in the colour than green.
- Grey olive and olive green contain some grey and some brown in the colour. They are not overly yellowish in themselves, but they will look yellowish compared to the deep olive and bronze green shades.
- Deep olive and bronze green both contain the most green, have no brown undertone and contain almost no grey.
Unitrade gives the perforation of this stamp as 12, like the others in the series that were printed by the CBN. However, as with the other stamps of this period, there were actually two perforating machines in use that gave slightly different measurements: 11.95 and 11.85. Both were used in combination with the other, so that 4 different line perforation measurements are possible: 11.85, 11.95, 11.85 x 11.95 and 11.95 x 11.85. 11.95 appears to be the most common of these by far.
In my study of these stamps, I have found five different varieties of the dextrose gum:
- A smooth, yellowish cream gum with a semi-gloss sheen.
- A smooth, cream gum with a glossy sheen.
- A smooth, light cream gum with a semi-gloss sheen.
- A smooth, cream gum with a semi-gloss sheen and a few irregular blemishes, which I call slightly streaky.
- A smooth yellowish cream gum with a semi-gloss sheen and many, regularly placed blemishes, which I call the streaky gum.
Here we have the creamy gum with the high gloss sheen on top, and the yellowish cream gum with the semi-gloss sheen on the bottom.
The horizontal pair on the left has the yellowish cream streaky gum, while the vertical pair on the right has the cream coloured semi-gloss gum with the few irregular blemishes.
This picture shows the cream gum that has the semi-gloss sheen. Apart from the slight difference in sheen, this gum is a much different colour compared to the high gloss gum, which appears more yellowish.
The dextrose gum stamps are only found with Winnipeg tagging. The gum had been changed to PVA by the time the General Ottawa Tagging was introduced in 1972. The tagging was applied in vertical bars down the perforations between the stamps, just as for all the other values that were tagged with 2 bars per stamp. The tagging bars are 8.5 mm wide, rather than 8 mm, and because of the size of the stamps and the width of the bars, the horizontal spacing between tagging bars across the sheet is different for the outer columns and the inner columns of the sheet. The spacing between the bars in on the left and right sides of the sheet is only 17 mm versus 18.5 mm for all the other columns in the sheet. The picture below shows the difference in these two spacing measurements:
- Upper left and lower left blocks will have the narrower spacing in the first column, and then wider spacing in the second column.
- Upper right and lower right blocks will have the narrow spacing in the outer column and the wider spacing on the inside.
There are no major or minor plate flaws reported to exist on this stamp, which is incredible given the number printed. There are also no reported plastic flow varieties. However, I would not assume that this means these things do not exist. One has to bear in mind that the vast majority of used stamps, many of which reside in large bundleware accumulations have not been studied in this manner. So, there likely are flaws to be found and discovered out there.
Perfins are not an aspect of this issue that I have touched on thus far, largely because I have not had any examples on hand with which to illustrate them. However, they are a separate collecting field unto themselves. A wide variety of organizations and bodies perforated their stamps in order to prevent or discourage employee theft. The scan below shows an example of an inverted CNR (Canadian National Railway) perfin on the Winnipeg tagged printing of this value:
Bringing it All Together
This has the potential to be an enormously complicated stamp because I have identified:
- Six different paper types, ignoring fluorescence.
- 25 variations of fluorescence.
- 7 shades, with more thought to exist.
- 4 different perforation measurements.
- 5 Types of gum.
- Wide and narrow tag spacing
An Important Announcement:
After nearly a year of development, the Brixton-Chrome Website is now live, with approximately 1,690 or so stamp listings from the 1857 Newfoundland Pence Issue through the 1972-78 Caricature 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 grand opening. I had originally aimed for July 31, 2018 as my date for the grand opening, but the migration from E-bay is taking much longer than anticipated, so I doubt I will be ready before the end of December 31, 2018. I have moved my estimated date back three more months as of last week because I do not wish to only spend time relocating old E-bay listings, but I wish to list new material as well. That being said, I would encourage you all to visit the site and get acquainted with the layout. Paypal is working now, as are payments by credit card.
You can visit the website by clicking on the following link:
Feedback received so far since the site went live on April 24, 2018 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:
- Catalogue number
- Item type, i.e. single stamps, plate blocks, booklets, covers, first day covers and cancellations, full sheets, used multiples and varieties.
- Condition and grade, i.e, mint and used, as well as the major condition grades.
- 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, have now been placed on sale at 25% off the normal prices until I close the store on E-bay, 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.
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.
