The 5c Atlantic Fishing Village Stamp of the 1967-1973 Centennial Issue Part One
However, there are many more attributes that show variation on this value, the chief among them being the shades of blue on which the stamp can be found. They run the full gamut, from very deep, dull blues all the way to deep bright blues. Yet, for some reason, they are completely ignored by Unitrade. In addition, there are the usual variations in perforation and gum that can be found also.
This week, I will discuss the untagged sheet stamps in detail. The remainder of this post will start with the dextrose gum stamps, and will finish up with the PVA gum stamps.
Untagged Sheet Stamps With Dextrose Gum - Unitrade #458, i, ii, iii, vi, xx, and xxi
Paper Attributes Other Than Fluorescence
The paper used to print the stamps with dextrose gum is generally always a vertical wove paper. However, There are several ways in which the physical attributes of the paper vary on the different printings. Ignoring paper fluorescence, the different paper types found on the sheet stamps with dextrose gum can be summarized as follows:
- A cream coloured paper that appears off-white against a stark white background. This paper has a highly burnished, smooth surface, which appears to have a light surface coating, when the printing surface is examined under a 10x loupe. There are no stray fibres visible on the paper surface at all. On the back, a light horizontal ribbing can just be seen on the gum, and this becomes much more visible when the paper is held up to a strong back-light.
- As above, except on this paper, there is no ribbing visible on the gum, and the mesh is much more difficult to see - even when held up to a strong back-light.
- As (2) above, except that the mesh is quite strong when viewed against strong back-light.
- A whiter paper, though still off-white when viewed against a stark white background. This paper shows the same burnished surface as the others, and no visible ribbing on the back. When held up to strong back-light and viewed, vertical mesh is very clearly visible.
- as (4) above, except that light horizontal ribbing is visible on the gum, and the horizontal mesh is very clear when the stamp is held up to strong back lighting.
- A cream coloured paper that is similar to (2) above, except that no mesh is visible, even when viewed against a strong back-light.
Paper types 1 and 2 seem to occur only on the dull fluorescent papers and low fluorescent papers, and it would seem that for each level of fluorescence, the paper is generally one type of the other, but not both. Paper type 3 seems to occur only on the non fluorescent paper. Types 4 and 5 are found only on the so-called hibrite papers, although I note that all the true hibrite papers that I examined, and the less bright high fluorescent papers were all type 3, while the medium fluorescent was type 4. Paper type 6 seems to occur only on the dull fluorescent paper.
As we shall see, there are several sub-varieties of each of these four basic paper types, which will now be discussed in detail.
Dull Fluorescent (DF) Papers
Unitrade lists only a single dull fluorescent paper. However, in reality there are several different varieties of papers that can all be termed as dull fluorescent. Some contain small amounts of fluorescent fibres, while most do not. Where the paper does contain fluorescent fibres, they are generally not present in sufficient quantity to change the overall appearance of the paper fluorescence from dull to low fluorescent. The colour that the paper appears under the UV lamp varies as well, as follows:
- Bluish white
- Blue grey
- Dark grey
- Greyish white
Non-Fluorescent (NF) Papers
I have found two different types of non-fluorescent paper on this stamp. One is a pure grey colour under UV light, while the other appears violet under UV. The key characteristic of NF paper, it that it will not appear whitish at all under UV, but will always be a shade of grey, brown, dark blue or violet.
The paper of the block on the left is a ivory grey colour, like the dull fluorescent paper. But the difference with this block, is that there is no whitish glow whatsoever, when it is viewed under UV light. So this is one variation of what Unitrade lists as non-fluorescent paper. The stamp on the right is a non-fluorescent violet grey colour under UV. The paper of the block does contain 1 or 2 high fluorescent fibres on each stamp, while the stamp on the right does not contain any fluorescent fibres.
Low Fluorescent (LF) Papers
I have found three varieties of paper that qualify as low fluorescent. It should be noted that while the low fluorescent papers all appear a brighter white under UV than the dull fluorescent paper, these papers do not appear especially bright when viewed on their own.
The first picture below shows the difference between dull fluorescent and low fluorescent paper:
The above picture shows the hibrite paper on the left, and a much deeper paper on the right. This paper is much bluer than the bluish white of the hibrite paper. This is what I would call a medium fluorescent to medium-high fluorescent paper.
There are several different shades of the blue ink used to print these stamps. Some of these differences are quite obvious, while some are subtle.
Let's take a look at the first of these below:
Now, let's look at the next two:
Now, we will look at two shades that are variations of indigo:
Let's look at another shade that is similar to the pale indigo above, but is slightly brighter:
Next, we have another bright blue shade that is similar to the deep, bright blue, but contains no greenish undertone:
Next, we have another relatively deep blue shade, again, without any greenish undertone:
I have identified nine shades here. Although, some of these shades appear to be associated with certain printings, I would expect that the possibility that all of them can be found with most varieties of paper and gum is quite high.
Under UV light the inks of all stamps except those on hibrite paper are non-transformative, given that they remain shades of deep blue under UV. The stamps on the so called hibrite paper appear to be printed in black ink under UV. Therefore I would classify the ink used on these printings as transformative in nature.
Several kinds of dextrose gum can be found on the various printings of these stamps. The different types can be described as follows:
- Smooth, yellowish cream gum with a semi-gloss sheen.
- Smooth, cream gum with a satin sheen.
- Streaky yellowish cream gum with a semi-gloss sheen.
- Smooth, cream gum with a semi-gloss sheen.
- Smooth, cream gum with a satin sheen and a somewhat blotchy finish. I have only found this gum on the so-called hibrite paper.
- Smooth cream gum with an extremely glossy sheen.
According to Unitrade, the hibrite paper did not appear until December 1971, after the 11.95 perforating machines were retired by the CBN. Therefore, it should only exist perf. 11.85 line. However, all the other printings should exist with four different line perforations: 11.85, 11.95, 11.85 x 11.95 and 11.95 x 11.85.
Unitrade lists a variety called the"line in 5". It is too difficult to see even on a 1200dpi scan, so I will not be able to illustrate it here. Basically it is a slightly oblique, very fine line that joins the top bar of the "5" to the semi-circular curve of the "5". It occurs on plate 3, position 11 of affected panes. According to a leading specialist in this issue, there is also another, similar flaw on the "5", except this time the line joins the top of the semi-circular curve to the bottom of that curve.
Unitrade lists the precancels on either dull fluorescent or hibrite paper. I would expect that the same range of fluorescence levels found on these papers should exist with precancels. My stock of precancels is fairly limited, so I cannot check this for certain. However, I can say that I have not found any examples of precancelled dextrose gum stamps on either the low fluorescent, or the non-fluorescent papers. So in this regard, Unitrade's listings would appear to be correct.
Bringing it All Together
Four plates were used to print the dextrose gum untagged stamps. Determining the number of possible combinations of paper, shade, perforation, precancel and gum is complicated somewhat by the fact that some gum types and perforation measurements will not, likely exist with certain paper types. Based on my study of the stamps that I do have, the number of collectible single stamps is as follows:
- Dull fluorescent papers: 10 x 5 x 4 x 2 x 9 = 3600 stamps.
- Non-fluorescent papers: 2 x 3 x 4 x 9 = 216 stamps.
- Low fluorescent papers: 3 x 4 x 4 x 9 = 432 stamps.
- Hibrite papers: 3 x 4 x 2 x 9 = 216 stamps.
- Dull fluorescent paper: 3600 x 4 x 4 = 57,600 plate blocks and 172,800 blank corner blocks.
- Non-fluorescent paper: 216 x 2 x 4 = 1,728 plate blocks and 5,184 blank corner blocks.
- Low fluorescent paper: 432 x 4 x 4 = 6,912 plate blocks and 20,736 blank corner blocks.
- Hibrite paper: 216 x 12 = 2,592 blank corner blocks.
Untagged Sheet Stamps With PVA Gum - Unitrade #458iv and #458v
According to Unitrade the PVA gum stamps for this value first appeared in December 1971, though an exact date is not given. This is the same month as the 1c stamps with PVA gum and is 3-4 months earlier than for the other low values that exist thus.
Paper Attributes Other Than Fluorescence
The paper used to print these stamps is again, a vertical wove paper. However, there are two distinct types of paper found, ignoring paper fluorescence:
- A very white paper that appears white even against a stark white background. This paper has a smooth, coated appearance on the face, and shows no mesh pattern when held up to strong back-lighting.
- A whiter paper that nonetheless appears cream coloured when viewed against a stark white background. The printing surface again appears smooth and coated. When you hold this paper up to a strong back-light, there are clear vertical striations visible in the paper.
Unitrade lists the paper of the PVA gum stamps as being either low fluorescent flecked, or low fluorescent without fibres. What is confusing to beginning collectors is that the basic colour of the paper under UV light often appears the same as many examples of the dull fluorescent and non-fluorescent papers. What makes these papers different is the inclusion of a much larger number of fluorescent fibres than the stamps with dextrose gum. The paper also often contains brownish woodpulp fibres that can only be seen under UV light. I call them woodpulp fibres, as they appear brownish under UV.
I have found 8 different types of low fluorescent paper containing various concentrations of fluorescent fibres, and in some cases, brownish woodpulp fibres, and one type of low fluorescent paper that does not contain fluorescent fibres.
The stamp on the bottom is a low fluorescent cream colour and for all intents and purposes contains no fluorescent fibres - at least not compared to all the other papers we have examined so far for the stamps with PVA gum. If you look closely with a loupe on the back, you will see a very sparse concentration of low fluorescent fibres only. But if you view it under UV without a loupe, it looks as though there are no fluorescent fibres. I believe that this is the paper that Unitrade lists as the LF PVA.
The first two stamps on the top row appear dull fluorescent blue grey, while the stamp on the top right appears grey. The upper left stamp contains a sparse concentration of low fluorescent fibres, a very sparse concentration of medium fluorescent fibres and very few high fluorescent ones. The middle stamp contains a sparse concentration of medium fluorescent fibres, and very sparse concentrations of low and high fluorescent fibres. The grey stamp at the top right contains a sparse concentration of low fluorescent fibres, a very sparse concentration of medium fluorescent fibres and very few brownish woodpulp fibres. So while these papers are all very similar, they are all different in ways that can be methodically described.
There do not appear to be nearly as many shades found with the PVA gum stamps as we saw on the stamps with dextrose gum. Gone are the extremes of the bright blues and the indigos and instead we have middle of the road, deeper blue shades. I have found 2 shades on the stamps I have examined so far:
There are two types of smooth PVA gum found on these stamps:
- A very thin, white, smooth PVA gum with an eggshell sheen. This seems to be found both paper types.
- A thicker, creamy PVA gum with a satin sheen. This gum seems to be found only on the striated paper.
According to Unitrade, these stamps first appeared in December 1971. Accordingly, they should only exist line perf. 11.85, as the machines gauging 11.95 had been retired fully by 1971.
There are no reported major plate flaws on the PVA gum printings, as all come from plate 5, and the only reported flaws involving the "5" come from plate 3.
Unitrade does list the PVA gum stamps on low fluorescent paper as existing with a precancel. This is listed as #458xxii. The listing would appear to suggest that only the low fluorescent paper without fluorescent fibres exists so precancelled. I do not have many singles at all of the PVA gum precancels to study, so that drawing definitive conclusions about what exists is difficult. However, all the stamps that I did examine were printed on the striated, cream paper, which gave a low fluorescent greyish white reaction under UV, with a very sparse concentration of low fluorescent fibres in the paper. The gum is the thicker, satin PVA gum. The shade was a near perfect match to Gibbons's deep blue.
Bringing it All Together
Only plate 5 was used to produce the PVA gum stamps. I identified 9 papers, 2 shades, 2 types of gum, a single perf, and precancels, which could exist with any paper or shade combination. So the number of collectible stamps, plate blocks and blank corner blocks could be:
- Stamps: 9 x 2 x 2 x 2 = 72 stamps.
- Plate blocks: 72 x 4 = 288 plate blocks.
- Corner blocks: 72 x 12 = 864 blocks.
