Canada Perforated Pence And Cents (1858-1867)

With regards to the Canada perforated pence and cents stamps (1858-1867), there is usually a range of perforations from 11.75 to 12.11 gauge which follow Kiusalas 67-11.75, 66-11.93, 65-12.11

Are there any more than these three from Kiusalas?

Hey jogil

Maybe a silly question...{ there is usually a range of perforations from 11.75 to 12.11 gauge }
Are these perforation differences caused by shrinkage do to water removal or are these perf. differences taken from mint stamps...??

Always watching any posts you do with reference to perforations...
Keep posting buddy.

Probably you know this artcile?

or is the information given there perhaps too old?
at least I took some of it for my notes some time ago.

wert: It would be mostly mint stamps.
stamperix: Thanks for the article.

Go to BNAPS website - Horace Harrison Library - http://www.bnaps.org/hhl/hhl-index.php

You will find a number of article on perforations of all time periods. The last 5 years are available to members only, but all previous issues are available to any one.

I have also looked at the different articles written by Richard P. Thompson of these perforations.

http://www.bnaps.org/hhl/n-pce.htm

Yes, there can be found those more recent articles by Thompson that I also thought but did not find again.

What is your experience of the stamps with unusual perforation like the 1c, 2c with (rounded) 11 3/4 x 12 or the 2c and 10c with one side 11.8 due to the damaged perforation machine, or also perhaps a black brown with 11.85 x 11.75.

Do they appear in exhibitions or auctions? Is there a chance that they will be listed in Unitrade one day, or has this all been a bit forgotten the last years?

I was told 11.7, 11.8, 11.9 and 12.1 which I assume to be around 11.75, 11.85, 11.93 and 12.11 but I am not 100% sure if this is what they meant or not.

Yes, indeed, that's why I wrote "rounded" above :). I think I saw some information about Kiusalas 66.5 but again I don't find my source anymore...

The stamps I mentioned in my last post are those which are not only about 0.1 (in the perf) different from others but quite distinct. Normally one would assume that the find their way into the catalog or into albums and exhibtions or auctions, but this is maybe not the case. Did you ever hear of any of the mentioned stamps the last years? (actually that's also part of the question what perforation exist - if noboy knows about the unusual ones, nobody looks for them)

When discussing perforated Pence issues one should be aware that an experimental perforation (14 X 14) does exist. These were done at the Kingston Ontario Foundry circa 1855-57. These are rare.

What Mike....????...Now you got me pulling out my stamps again.

You will find it mentioned in many books. Unitrade 2020 mentions it on page 40. No number but is written up under #4.

Found it Mike...Thanks

Are these not private unofficial perforations?

They are experimental perforations. Here is what Winthrop S. Bogss says:

"Some of the sheets of Three Pence were undoubtedly taken by the Post Office Officials and experimented with as at least three forms of roulette, and perforations 14 are known. It is also possible that some bank or insurance company may have had some sheets perforated or rouletted for their own convenience."

I consider these as similar to bisects. They were officially used to send mail.

Mike

Are the perforations exactly 14 per 2 cm or just a touch over such as 18 holes or pins per inch (/1.27) which is around 14.17 per 2 cm?
