US And Canadian Stamps Used Together?

Hi I wonder if US and Canadian stamps used together is a "thing" or just a mistake. I had three stamps on a piece with a Canada (I think) "March of Dimes" cancellation.
Is this just a mistake by someone trying to make up the total or are the US stamps included "like Cindarellas" but the 5c Canada covered the postage. Does anyone collect these or is this just an oddity.

Thanks again

I live in the US, and have been been watching our personal, and company, mail since the early 1970's. I think it's just a mistake or prank but it's still collectble postal history since it went through one or both mail systems. Maybe there are other examples of neighboring or predecessor/successor or origin/destimation countries stamps being used together. Interesting idea ...

Nice, but too bad the whole cover was not kept

Agree @petert4522 - this was stuck in the back of an album of Newfoundland and Canada stamps that I bought - the back had revenue and cindarellas and this item. I think it was a Canada cancel unless you have March of Dimes in the US. I remember filling up cards as a kid with dimes to collect. I lived on the US border growing up and it was more of an idea as farms straddled and shopping was on both sides. We could have been back and forth 5 times a day. US and Canada coins were used interchangeably also BUT then things got weird and the border "hardened" a lot. I still don't remember ever using US stamps though....

It is a US cancel

Actually, it's not uncommon. I live on the Canadian border. Often a person prepares a mailing to Canada, then realizes that he'll be in Windsor the next day and adds Canadian postage and drops the envelope in a Canadian mail box for delivery. Many Canadians work in the United States and vice versa, crossing the border daily. With current mail service, it saves about 7-8 days in delivery time.

I find these multiple frankings very interesting. Especially when the stamps are used as above to pay the postage as the mail enters the postal system. It's fun to try to figure out why stamps from more than one country would be used. I have one to share but it's not US + Canada. Should I post it here or start a new thread? I'm hoping to see examples that others have as well!

I will occasionally place other Countries stamps on outgoing letters to spice things up. I just make sure of course to have enough US postage applied.

The March of Dimes originated in the U.S. It was founded by President Franklin D. Roosevelt and because of that his image has appeared on U.S. dimes since 1946.

The latest issue of the journal of the British North America Philatelic Society includes an article illustrated with many covers where Centennial era (1967) Canadian stamps were used to mail letters from the US and Europe.

Interesting replies. Thanks. I find this interesting and the idea of having a letter in the car that is then mailed from the States would be interesting. What was the mailing rate for a letter from US and from Canada at the time of these stamps?

PS March of Dimes may be in the US but it is a major Canadian charitable cause also so the cancel saying March of Dimes does not necessarily mean it is a US cancel unless you have other ID reasons

Hi,

Here a 6 cents rate in Montréal. Dated 23-01-1970. Next postal period started on 01-07-1971 at 7 cents.

@hornet785 I wonder if it was the same with coins and with stamps where there was a laissez faire attitude sometimes. As a kid we could use US and Canadian currency interchangeably at least in close proximity to the border. Maybe it was the same with stamps - not worth the bother to make a fuss about it...

Coins are usually no big deal. I work in retail the Cleveland, Ohio area and their
have been scammers who would take advantage of unknowing cashiers and use $20 Canadian traveler's checks to make purchases and profit from the exchange rates.

@hornet785 Nice cover and it seems there are quite a few of these.
