The 10c Jack Pine Stamp of the 1967-73 Centennial Issue Part Two

Image
This week's post is the second of three posts that will explore the printings of the 10c Jack Pine stamp from this issue. This week, I am looking at the printings that bear the experimental PVA gum that collectors refer to as "spotty white gum". It was a very shiny PVA gum that was at the same time streaky. In many ways it almost looks like a hybrid between the older dextrose gum and the matte PVA gum found on the later printings. It was in use for only a very short time in 1971, as evidenced by the fact that only three commemorative issues from 1971 are found with this type of gum:


The Emily Carr stamp, that was issued on February 12.The Radio Canada International stamp, that was issued on June 1.The Census Centenary stamp, that was also issued on June 1. Unitrade lists three basic varieties of this stamp with this gum type, which were issued between December 1971 and January 1972. All of them were reportedly printed on hibrite paper, and are as follows:

The 10c Jack Pine Stamp of the 1967-73 Centennial Issue Part One

Today's post begins my examination of the second of the high values of this series: the 10c olive green stamp depicting Tom Thompson's "Jack Pine". It has the second highest number of listed varieties in Unitrade behind the 15c Bylot Island. It is the only stamp of the entire series to have appeared with the experimental "spotty white gum" that appeared at the beginning and middle of 1971.

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…

The 8c Alaska Highway Stamp of the 1967-73 Centennial Issue

Today I begin to examine my favourite part of the entire Centennial series: the high values. These stamps were all reproductions of paintings by members of the famous Group of Seven. The high values consist of an 8c, 10c, 15c, 20c, 25c, 50c and $1 value. Today's post will explore the first of these, being the 8c.

The stamp was printed in shades of purple brown and depicts the painting "Alaska Highway", by A.Y Jackson. It was only a high value during the period, when the first class letter rate was less than 8 cents. When the letter rate increased to 8c on December 30, 1971, this stamp ceased to be issued and was reduced to low value status and replaced by the 8c Parliamentary Library design that was the subject of my posts for the past several weeks. Because it was replaced at the end of 1971, it is not known to exist with PVA gum. Though it seems curious that it doesn't since there were plenty of stamps issued in 1971 that at least were the experimental spotty gum …
