The Coil Stamps of the 1967-1973 Centennial Issue
The coil stamps were all printed by the Canadian Bank Note Company. They can generally be divided into two groups:
- The initial issue printed in imperial dimensions, which consisted of the 3c, 4c and 5c. These were printed in rolls of 500 stamps each, with starter strips at the front of each roll that consisted of 10 blank, stamp sized cream coloured labels. On the end of the roll, after the 500th stamp, would be an end strip consisting of 10 stamp sized blank, coloured labels. The colour could vary (yellow on the 3c and pale red on the 4c for instance). The denomination of the stamp was usually handstamped on one of these labels, in dark purple.
- The metric issue, which consisted of the 6c orange, 6c black, 7c and 8c. These were issued in rolls of 100, which had no start or end strips.
- The imperial sized coils were produced by joining long rolls of stamps together to form rolls of 500 stamps. The rolls were produced from more than one revolution of the printing cylinder, which is why jump pairs and strips exist. The joining of the rolls together creates paste-ups. The strips themselves were cut from larger sheets and guide markings were placed in the margins between the strips to aid in placement of the cutting mechanism. Slight mis-alignments create cutting guideline strips.
- The metric sized coils were produced in sheet form first, rolled into rolls of 100 stamps, and then those rolls were scored between the rolls, with each roll being snapped off along the score lines. The rolls were wrapped and the wrapping contained printed text saying "Roll-Pac" with the denomination. The wrapping was also scored where the rolls were to be snapped off. Entire tubes would be shipped to post offices, where the clerks would snap them apart before selling them to the public.
- There is a short vertical line printed in a darker shade of blue,
- and then a wider, "T" shaped marking beside it.
It is very, very slight, but if you look carefully at this strip, you can see that the left margin of the top pair in the strip is very slightly wider than the left margin of the bottom pair. Here is a closer look:
- There is a smooth, yellowish gum that has a satin sheen.
- There is a smooth, yellowish gum that has a streaky appearance.
