The CBN Booklet Stamps
The 1c booklet stamps printed by CBN were only issued as part of the 25c red and white booklets that were issued between February 8, 1967 when the set was first released and September 1968 when the next 25c booklet containing 4c and 1c stamps replaced it. Consequently, all of the booklet stamps exist only with dextrose gum. Since the stamps were only printed between 1967 and 1968, they would all have been printed from plate 1 and 2.
The papers employed to print these stamps is similar to that used for the sheet stamps, with some differences:
- On nearly all of the panes and singles that I examined, I could see a very thin surface coating that gives the printed surface a smooth, burnished appearance.
- The paper is a horizontal, rather than vertical wove, as evidenced by the fact that all the stamps with gum curl in the horizontal direction.
- The paper shows a fine vertical mesh that is most pronounced and visible on the gum side. This is not present on any of the sheet stamps.
Finally, Unitrade lists 4 different levels of paper fluorescence, while McCann lists six:
- Dead or non-fluorescent (NF)
- Dull fluorescent (DF)
- Low fluorescent (LF)
- Low fluorescent with fibres (LF-fl)
- Dull with fibres (DF-fl)
- Medium fluorescent (MF)
On the right we have the ivory white DF paper that shows no significant fibres. Next to the pane on the left it actually looks almost LF, but it isn't. The pane on the left is a dull fluorescent violet grey, with a sparse concentration of high fluorescent fibres.
The shades found on these stamps closely follow the shades seen on the plate 1 and 2 sheet stamps printed before September 1968:
- Deep brown
- Deep chocolate
- Blackish brown
The left stamp is deep brown, while the right is deep chocolate, the difference being the very slight reddish undertone to the deep chocolate, that is absent in the deep brown.
Given that the 1967 commemorative issues exist with all four perforations: 11.85, 11.85 x 11.95, 11.95 and 11.95 x 11.85, one would expect that these stamps should exist with all four perforations. However, all of the singles and booklet panes that I examined were perf 11.85 only. That is consistent with the findings of Julian Goldberg in his study of perforations on these booklets and it may suggest that the 11.95 machines were simply not used to perforate the booklet stamps, even though they were used to perforate the other issues. So for the purposes of this post, I will assume that 11.85 is the only perforation that exists.
The gum on these panes seems to come in only 2 types:
1. A very shiny ans smooth yellowish cream dextrose, that has a semi-gloss sheen, and
2. A thinner, less yellowish cream gum with a satin sheen.
I have not yet found examples with streaky gum, though I am sure that they probably do exist. The scan below shows the first two types:
- Paper that shows a very slight vertical mesh that is clearly visible when the stamp is viewed against backlighting. You can also see the mesh as light ribbing if you view the gummed side at an angle and move it around under a strong light.
- Paper that shows no mesh pattern even when viewed against strong backlighting.
The top pair is the plain DF paper with no fluorescent fibres that has a greyish cast under UV. The stamp on the right is a DF to NF light violet under UV with an overall sparse concentration of MF and HF fibres. The bottom pair is a DF paper with a violet grey cast, and very few low fluorescent fibres. Each of these comes from the 4c +1c booklets, so that it would appear that there are at least three fluorescence levels, and possibly 6 paper types in total for these stamps.
The left hand stamp is from the 6c + 1c booklets and it is a dull fluorescent brownish grey colour under UV. Generally, the DF papers for these stamps seem to be more brownish grey and lack the violet undertone. They also exist with a sparse concentration of dull to low fluorescent fibres. Finally, both McCann and Unitrade list a hibrite paper, that is bluish white, but in my opinion is really more of a high fluorescent, rather than a true hibrite.
Generally speaking the dull papers on the 6c+1c booklet stamps tends to appear more brownish grey under UV, while the 4c + 1c booklet stamps appear more of a grey and violet grey.
The picture below shows these types:
This is a much shorter post today and concludes my exploration of these first booklet stamps of the 1c. Next week, I will look at the perf. 12.5 x 12 1c BABN stamps that were included with the 25c, 50c, and $1 booklets that were issued from late 1971 onwards. These are much, much more complicated and require a post all on their own.
