Scott 10 Perforation Stamps.

Hi guys..I think there are only 4 stamps that Canada Post printed with a perforation of 10...They were experimental perforation stamps as shown below...

SCOTT #482


SCOTT #483


SCOTT #484


SCOTT #490


Also there is a variety in the Scott #482...Called "big wave/small wave" as seen below..

It would be more accurate to say that there are only 4 commemoratives that British American Bank Note printed with a perf 10.

Literally speaking, Canada Post does not print stamps; they get other companies to do so. In this instance it was the printer, BABN, that did the experimenting of the perforation, not Canada Post.

BABN They also printed the 6c Centennial design (orange and black) with this perforation.

Also Centennial stamps such as 1 cent brown (454d), 4 cents red (457d), 5 cents blue (458d), 6 cents orange (459, 468A, etc.), 6 cents grey (460g, 460h, 468B), 7 cents green (549), 8 cents black (550).

Correct, and, some of those stamps were a real pain to separate too.

Yes they were a pain and unless you bent them back and forth
a couple of times and put a crease in the perf there was
a good chance you tore out a chunk of the the stamp.

And as I recall that's the reason Canada Post finally
ordered BABN Co to change the perforations.
Too many complaints from the public.

The U.S. had similar problems with perforation 10 from 1914 to 1917 for their sheet and booklet stamps so that it was changed to perforation 11 for flat plate printings.
The U.S. had similar problems with perforation 10 from 1919 to 1926 for their sheet and booklet stamps so that it was changed to perforation 11 x 10.5 for rotary press printings.
However, perforation 10 worked very well for U.S. coil stamps from 1914 to 1917 for both flat plate and rotary press coil stamps and for only rotary press coil stamps from 1917 on wards.
