Canada #403 3c Purple Queen Elizabeth II, 1962-1967 Cameo Issue, a Group of 9 VFNH Plate 2 Blocks on DF Paper Showing Different Gums, Perfs and Shades
A group of 9 VFNH (VF-75 to VF-84) plate 2 blocks of 4 of the 3c purple stamp of the 1962-1967 Cameo Issue, which will include unlisted perforation and paper variations as discussed below. As explained in the blog articles here, here, here and here, these stamps can be found with a variety of paper, shade, tagging and gum varieties, some of which are listed in Unitrade, but most of which are not listed. These articles will explain what these varieties are and how you can identify them.
This lot includes:
- UL printed in deep purple, with streaky gum.
- UR printed in deep purple, with both smooth and streaky gum.
- LR printed in deep purple, with smooth gum.
- LR printed in light plum with both smooth and streaky gum.
- UR printed in light plum smooth gum.
- LR printed in intense milky purple with streaky gum.
- UL printed in very pale plum with streaky gum.
I have not checked these blocks specifically for the paper types and perfs, but the notes below will prove helpful.
In terms of paper, Unitrade only lists the untagged stamps on DF paper, except for some printings of the 4c, which are listed as existing on fluorescent paper. There are at least two types of DF paper that can be found, as well as NF papers. This lot includes some of both types that have not been specifically identified, but which will generally be 1 of 2 types of the DF paper as follows:
- A vertical wove paper that shows no clear mesh.
- A vertical wove paper that shows clear horizontal mesh when viewed from the back (sometimes referred to as "ribbed")
Also, in most instances, the paper is opaque, showing only a faint image of the design through the back. However, some stamps are found with more of the design visible on the back.
In terms of gum, there are generally three types, two of which are present in this group:
- A smooth, cream coloured gum that has a semi-gloss sheen.
- A streaky, cream coloured gum that has a semi-gloss sheen.
- A grainy cream coloured textured gum with a satin sheen. This is not present in this lot, but has been seen to exist on the 4c value.
In terms of shades, there are subtle variations on the 1c, 2c and 4c, and the 3c and 5c values show clear variations.
The perforations also vary due to the fact that CBN used up to four different machines to perforate sheets during this period. The old machines gauging 12 and 11.9 were used to perforate most of the original printings, and then the newer machines were used for the later printings. One of these new machines gauges 11.95, while the other one introduced sometime in 1961 gauges 11.85. Compounds can also be found of both these gauges, so that all sheet stamps can be found with many different perforation measurements that at least include: 11.95 x 11.9, 11.95 x 11.85, 11.9 x 11.95, 11.9, 11.95, 11.85 x 11.95, 11.85 x 11.9, 12 x 11.9, 11.9 x 12 and 11.85 x 12. Several of these will be found in this lot, though I did not measure the perfs of these blocks specifically.
Unitrade lists these blocks at $11.25 in this grade. A wonderful opportunity to get started on a more specialized collection of the plate blocks of this issue.
