The `Double Dot Right of Roof` variety.
Sc 544. A reported variety.
Just as prominent as the Extra Spire but
twice as hard to find.

This stamp has a dot between her eyes.
On the bridge of her nose.
This is not a reported variety but I have four examples.
Notice how the dot varies in size. Sc544.

A mark under the `N`, in the perfs.
This is a listed variety. Sc 544.

This one has a large mark in the lower
right margin. Looks like two dots joined
together. A reported variety. Sc 544.

A double dot in the top right margin.
Sc 544. A reported variety.

New: The perforation change that started in 1962 has also affected a centennial stamp so far as well but in the opposite way. Centennial stamps are supposed to be new perforation 12 (11.85) but the booklet pane Scott/Unitrade 458a has been found with both new perforation 12 (11.85) which is commoner and old perforation 12 (11.95) which is scarcer. It appears that since booklet stamps required less perforating wheels to be used because they have straight edges, the older perforation wheels with older perforator that was still left was used for some of this booklet pane.

This is the `Dot Below Necklace` variety.
Sc 544. Reported Variety.
I posted this on the bottom of Page 11 but I got
it wrong. That`s not the variety.
This is the correct variety and I have four copies.

Besides 458a having new and old perf 12, there is potential for 454a, 457a and maybe 455a to have both perfs too. These are being checked.

Two varieties here, Dot on Neck and dot in the right
margin near her shoulder. I posted the `Dot on Neck`
on page 24. Now I have found 3 more copies and they all
have a dot in the right margin. This is not a reported
variety.

What philatelic literature on the Canada Centennial Issue do you suggest?

The old perforation 12 (11.95) is on the Centennial 5 cents booklet pane (458a) on the right since the perforation holes are slightly smaller and more clogged up than the new perforation 12 (11.85) on the Centennial 1 cent (454a) and 4 cents (457a) booklet panes on the left. I have been looking into the 454a, 457a booklet panes and 457b, 458b miniature sheets for old perforations but I have only found new perforations so far. I am also looking into 401a booklet pane for new perforations but I have only found old perforations so far. The old line perforation 12 (11.95) has long existed on Canadian stamps from 1861 to 1967 while the new line perforation 12 (11.85) has short existed on Canadian stamps from 1962 to 1972. The overlap between both perforations in the 1962 to 1967 common transition period presents over 20 different stamps with both perforations (over 40 stamps when counting both together).

Here is another reported variety. A large mark
next to her eye. Sc 544.
