Canada Centennials Printing Varieties.

Please explain Ezperf.

Gosh my heart started pounding. I thought someone
had posted to talk about centennials

Use the search function at the top of the page.

This stamp has a pair of dots in the lower
right corner. One is under the middle A and
the other near right frame line. Sc 459.
Perf 10 plain paper. It`s a reported variety.

I've been going through 6 cent black centennials and came up with some that look like the "slight doubling of the 6" variety. Is this found in a single position or more than one? Below is a pair, both of which appear to have doubling,plus two singles:

That first one sure is a nice example.
I have a strip of 3 all with doubling.
I believe it`s found on the left side
of the sheet and probably down the sheet.

Does anyone have a vertical pair, with one or both having the doubling? That would help determine location a bit. I'm surprised because I found quite a few of these and I expected it would be more scarce, given the Unitrade catalogue value.

This one has a large mark just to the left
of the top of the library. Not yet reported.
So far I have only the one copy.

I'd appreciate comments on these 8c blacks. Are they the "scratch on forehead" variety? All are general tagged. I have found a lot but the problem is they seem to be on both low fluorescent and medium-to-high fluorescent paper. The first is low, the rest higher fluorescence. The third also has a dot on the forehead. The fourth looks most like the examples I have seen here and elsewhere, but it too is higher fluorescence.

Well first of all the colour is slate not black.
The top two stamps are examples of heavy inking that
are just starting to drag to the right.
The bottom stamp is the scratch on forehead variety.

Here`s some nice `scratch on forehead` examples:




Examples of the dot on forehead variety:

Thanks alanl - but back to my question: Why is the "real" scratched forehead stamp on higher fluorescence paper (it falls between "medium" and "high" fluorescence on my reference set of fluorescence in Canadian stamps) and not the low fluorescence that Unitrade says it should be on?

Thanks for showing all those varieties alanl, I didn't know there
are so many.

Even though I'm not really into flyspecking you're posts have piqued
my interest and I might check my Centennials, most of which I have not looked at in 30 years.

BTW I see that most if not all the stamps you show are used.
You don't collect mint? Did you get your material from kiloware ?

lithograving...thanks for your interest...I enjoy your threads and posts too...
I started buying on paper mixtures about 1990 and I have several hundred
thousand off paper that I am going through...I still have 80 pounds on paper.
I have a small mint collection.

More on 544pviii - the "scratch on forehead" 8 cent slate (not black.) Here are two stamps I think qualify as the variety, but one is on low or dull fluorescent paper (that is listed in Unitrade) and one is higher fluorescence (not listed, unless I have missed it . . . ) The stamp on the left in the UV photos is the same as the first one:

I just went through an envelope of varieties and
picked out 6 scratches...5 on HF and 1 on LF.
It may be that the editor of Unitrade decided
to list just that one brightness.
All 6 were 2 bar tagged.

Okay, I'm not crazy - thanks for checking.
