1955 S 1C stamped over canadian 1C

I have again connected the dots of the Royal crown on an uncirculated coin... At first it appeared as though it were riddled with carbon spots... I believe it is not.
This is not the first coin like it I have found...
I have others..
Who would be the best expert on the subject to send the coin to for authenticity?

It's highly unlikely that such an error could occur, so your best bet is to post a clear, cropped picture of both sides. There are a number of experts on here who can provide feedback after seeing the pics.
Since you said you found others as well. Maybe you're confusing damage or other markings with what you think is an error. Once again, pics will help.
Good pictures will definitely establish what you have. We have experts here to help you with such issues. Cheers, RickO
Probably either an optical illusion or a sandwich job. Best case, a mint worker screwing around. Why would the US Mint have canada cents?
They could happen

Before you spend money submitting it,
why not post good clear photos of both
sides of it here, and you'll get numerous
opinions and facts.
FYI - The US over Canadian Quarter wasn't found in change. It was found with other "dubious" San Francisco mint errors in an unclaimed safety deposit box (as written in the Snopes article). While no hard evidence exists (as far as I know), the general opinion is that these errors had "help" from someone on the inside. So the existence of this example is not necessarily an indication that other US over Canadian coins could have been struck and entered circulation.
BTW: I believe some CU members may have been involved in the authentication of that coin.
It's more than highly unlikely, it's impossible. No Canadian small sized cents had ever been minted through 1955 showing the monarch wearing a crown.
edited to add...
The first year a crown was used was in 1965. How that got struck with 1955 US cent dies would be an interesting story indeed.
Just to clarify, 1920-1936 George V cents had a crown on the monarch. However, I get your point, how would a 1936 (or earlier) cent find it's way into the minting process
You're right, I'm an idiot. I was thinking of the large cent variety for George V. Apologies.
I came back to remove my post once I realized that, but since you've quoted it, I'll just leave mine as a monument to stupidity.

I stand by Mint worker shenanigans. No other way that happens
So you were there?
It's a clad quarter struck on a 30 year old silver planchet. How else?
Lots of ways, but I was not there so I do not know.
I will post pictures later this afternoon .. They are on my laptop and I am away from it for the afternoon.
As far as confusing Damage? Wouldnt you think it more likely the mint were stamping other coins rather than me seeing a key piece in the puzzle.
One coin I uave is circulated and could very well be just damage... But the uncirculated coin?
I will outline what I see before I post it...
The only answer to that question would depend on the cost of Canadian coins vs. Cost of Making our own at the time...

I think you guys are being trolled. Look at his other posts.
Even if clear picks show what you are saying, I'd guess Chinese counterfeit before genuine mint product.
.....or probably a man-made 'sandwich' coin
The US Mint hasn't repurposed planchets in probably 200 years
The composition and weight are different. You could not use Canadian planchets for U.S. coins, and especially not silver ones.
If the OP had one of these unicorns I'd say it was almost definitely impossible, but they claim to have found multiple examples. There's the answer right there....
Scrolled all the way through...
Where’s the pic?
