Canada Tagged Stamps

[Admin Bear]

I have a question about the tagging on the 1960's and 70's Canada tagged stamps.  Do you need an UV light to see this or can this be seen with the naked eye???

I know that the US tagged stamps cannot be see without a UV light, but on my Great Britain collection you can see the phosphor bars by holding the stamps at an angle.

Any help would be appreciated.  :cheers:

These links are about tagging errors but I think still useful to you.

Tagging on Canadian stamps is sometimes noticeable and at other times not. Early issues can usually be seen with the naked eye. From 1962-1972 we used a system of tagging called Winnipeg tags, which were phosphorescent. Winnipeg tags came 3 different ways. Winnipeg 1 bar, 2 bar and centre bar. 2 bar was a bar on both sides of the stamp, 1 bar was a bar on either side of the stamp and centre was just that.

After 1972 we began a process of fluorescent tagging however early issues (1972/73) had an issue with the tagging being migratory. That is when the tagging could transfer to other issues and produce "apparent" tagging errors. After 1973 we were able to get inks that were non-migratory and thus more stable. Since then there are at least 12 different tagging types, there may be some new ones since my last catalogue was published.

Most tagging can be seen with a long-wave uv light. Shortwave lights are the standard for US stamps.

Here is a copy of the tagging page from the 2011 Unitrade catalogue.

Thanks Ross, I have copied and saved that page on my computer for later use.  

You Rock!!!!!!!!!! :rocker:

This is  study on Tagged stamp of Canada the 1967-1973 Centennial Definitives, and here you can see the winnipeg tag centre bar ,2 bar and right and left bars on the stamps the tagging bar turn a bit darker over time on the stamps there are also different types of paper used ,Hibrite, high fluorescent, you need to use a long wave ultra-violet light to see them.some times you can see the difference by turning the stamp over and observing the paper color,and tags. Ive been working on these stamps for a while now and have come up with a several varieties on each stamp, as well as errors ,which i will start a thread on as soon as i get it together.

Johnny, thanks for showing that page of tagged stamps.  I definitely can see the tagging on some of the stamps.  Now I know what to look for.  If I find some, I will put them in my album.  I just don't want to spend the money on a UV light right now.

Thanks again,
Kris
