Canada Centennials Printing Varieties.

Note that used stamps are notoriously difficult for accurately assigning paper fluorescence grades. Stamps soaked off of envelopes with high amounts of whiteners can get contaminated and show up as being more fluorescent than they were when they were mint.

When you're going through huge amounts of used stamps, you can sometimes see trends in the different levels of fluorescence (eg an MF stamp might look "scratchier", the individual paper fibres have more varying levels of fluorescence). But in general, it's real tough to make accurate calls on used stamps, so they will be using mint stamps to come up with their decisions on what grades get listed in the catalogue.

That's not to say that they have everything covered 100%. A while back on another thread I posted some photos of my collection of Centennials numbered by Darnell numbers. I think there are something like 198 major varieties or 205 varieties or some such number. There are a few varieties that have since been added to the Unitrade listings that weren't known about at the time, so discoveries continue to be made. (By variety, I mean face different / paper / gum / perforation / tagging / booklet single / coil, not things like the lobster trap variety.)

The 8 cent centennial HF stamp has a very distinctive look.
The five `scratched forehead` stamps I looked at last night
were HF. I doubt they were affected by whiteners.

It looks like the Queen is winking at us on
this under inked stamp.





Merry Christmas to all the Centennial fanatics on SCF.

The 7 cent stamp was printed as sheets of 6 panes of 100,
3 panes across and 2 down. The 3 panes on the top of the
sheet had the plate numbers. Some unknown object caused a
series of dots in the bottom margin of the second row of
the top 3 panes. All 30 stamps across the sheet have dots.
10 stamps have 2 dots and 2 are found in the selvege between
panes for a total of 42. There is a pattern to the dots,
they are not random. All dots are about 1/4 mm below the
bottom frame line. Found on Plate #1 only.







Well...there`s the first 42 varieties on the 7 cent stamp,
only 50 to go.

Sc 543...`horn on top of seven` variety.
It`s a reported variety.

Here`s another reported variety..."A small hook shaped
flaw on the right frame line opposite the Queen`s ear"

Here we have a pair of dots above the ST of POSTAGE.
Sc 543. A reported variety.

Sc 543...dot under D.
Similar to #31 and #40 posted in the group of
42 on this page but not the same.
This one has a slightly different horizontal position.
And it`s lower vertically. Reported variety.

A dot in the lower right corner of the margin.

Hi.

Here is the Scott 455 Totem pole "eyes" variety. There is supposed to be 33 possibility that have been identified as stated in my Unitrade 2012. I only have 4 of the possibilities.



I am not sure about the rarity factor of this variety. It seems that Unitrade did not assign any minor number (would probably have to set 33 of them?). It does not seems to affect the value of the stamp.

Peper_jack, I have 11 of them so far.
Among the 33 possibilities, are we including the half eye closed

Following is an example of the possible dispositions of the "blinky".

#455 - Missing part of the tree along the edge

This chart was printed in the Centennial Study Group
newsletter #69.

alanl, can we presume the eye completely white would be the fourth stage?

I didn't know about the different stages... In fact, I was wondering where the "33 possibilities" could come from if they are "opened" or "closed"... it should be only be 16 possibilities (4 eyes with 2 possibilities, so 2 x 2 x 2 x 2 = 16). Now,I will have to check to see which stage my stamps are.

Thanks for the info.
