Canada Scott 411

Here are two different Canada Scott 411 mint matched plate block sets.

The second set was ten times harder to put together than the first set.

What is the difference, Jogil?

411 new found perforations: old 11.95 (common), new 11.85 (scarce).
Reference: The Canadian Stamp Perforation Change of 1962 (booklet).

Thanks for the explanation Jogil

Same is true with Scott #399 also

Unitrade 2015 covers this CBN perforation change, indicating SC334, 338, 340, 343, 351, 362, 363, 399 and J15 through J20 as well as the possibility of others.

As Unitrade does not indicate or suggest a different valuation for these variations, does any other catalogue indicate their values?

Subsequently corrected initial entry of J10 to J20.

BlackJag...
where does Unitrade 2015 mention the above perf changes?

Is it the Unitrade 2015 Canada stamp catalogue and/or the Corgi Times that mentions it?
Currently 320, 321, 402a, 404a, 405b, 405p and 411 can be added to the above list for these perforations.

2015 Unitrade page 148 below SC 399.

Although I've been a member of the Elizabethan II Study Group for the past few years, I don't remember seeing anything on this subject, but it may have been in an earlier issue.

It was in Volume 21 (124), # 4 Jan-Feb (2013)
The Canadian Stamp Perforation Change of 1962

Just ordered the ""The Canadian Stamp Perforation Change of 1962
"" on line..Might be a good booklet to have in a collection.

It's a MUST have. A perforation change is another whole new stamp.
Look at the differences in the Fruit Trees issues of 1991-96.
These perf changes are harder to detect (from 11.95 - 11.85) - but should be no problem for a fly-specker like you!
I have quite a few of them.

Here's a way to look and contrast the perforation differences. The perforations on the right are purposely lined up, but they naturally don't stay lined up due to the differences between them.

Thanks jogil,

Your scan is very helpful.

It also shows that comparing a single stamp will not indicate the perforation change, even with this large format stamp. ie. Looking at the right most stamp in the comparison, there is no difference within that stamp (along the top edge), it is only when the second horizontal stamp that is attached does the slight difference in perforations becomes noticeable.

I collect these in plate blocks because in some issues with multiple plate numbers, they only occur in specific high plate numbers.

Hi jogil,

I understand your collecting habits.

But for the average stamp collector who only collects stamps as singles, then comparing a single stamp against another single stamp very well may NOT indicate a perforation difference. In fact. even if a perforation gauge were used, then determining a 11.85 versus 11.95 perforation may be near to impossible.
