Winnipeg Class tagging - Canadian stamps 1962-1972
Can anyone tell me what I am looking for on Canadian Christmas stamps
and assorted other issues. Are these phosphorescent like the British stamps of the same period or are they fluorescent like Ottawa tagged stamps from 1972 onwards? Thanks, Patrick |

Winnipeg tagging is similar to Ottawa, but instead of showing green, in a
dark room when you turn the UV lamp off it will glow for a few seconds... you can see it with the UV lamp on depending on the issue... hope this helps... kk "K.

Thanks, Patrick Patrick: Which year's issues are you referring to? Christmas issues are issued almost every year. Canada has issued both types of stamps. [eg The 1966 Xmas issue exists TAGGED (Scott 451p and q and 452p) and NOT TAGGED (Scott 451-2).] From 1962-73 various experiments took place with taggung / luminescence. From Scott 611 (Jan. 31, 1973) onward most, if not all stamps are "tagged".

Winnipeg tagged stamps were phosphorescent and Ottawa (or General) tagged stamps were fluorescent. With Winnipeg tagged stamps, you can just barely see the bars without needing a light. Usually, they glowed a bright greenish-white shade. The bars were either wide, narrow, on one side or the other, both sides, or in the middle. It depended on the letter rate, plus they were experimenting on what worked best for the equipment. Ottawa tagged stamps, OTOH, glow a bright green. Although on older issues with the Type 1 tagging (with migrating phosphor) they now have a dim yellowish appearance. All of my issues with this compound have bled into the entire stamp, mount and page, leaving just a faded ghost of the original bars. Later changes produced a more stable formula, so that it stayed where it was applied. Ottawa (General) tagged issues were mainly two bar - that is applied between the stamp design over the perforations from top to bottom. There are variations to this, and now, most are applied around the circumference of the stamp. Some exceptions being where the design juts into its neighbour - then there is a break in the tagging. Thge 2002 48 cent 100th Anniversary of the Canadian Postmasters and Assistants Association is one example of this. IIRC, all Canadian glow in the long-wave light. American stamps, I know, used the other opposite wave (short if Canadian used long.) -- Pete Ware Thomasburg ON Remove the obvious when replying by e-mail - I'm fed up with the latest virus! |
