There have been a few people in the past on the forum who believe they found a 1970 proof US quarter struck on a 1941 Canadian quarter.
Here was my response to the last one:

The 1970 struck on a 1941 Canadian quarter was not only a proof strike (meaning it was not issued for circulation and therefore would not have been found in change, bank rolls, or mint bags) but a UNIQUE coin. There will not be another identical coin out there. Even if there was another 1970 Proof quarter that was struck on a 1941 Canadian quarter (Unlikely considering this is the only US coin struck on a Canadian coin to my knowledge), the chances the date 1941 would be in the exact place as the known example is ASTRONOMICAL. The Canadian coin would have to be the right side up in the striking chamber AND be rotated in an exact way for the AMERICA to be struck onto the date.

So, like I said before, you finding this coin would be astronomically unlikely.
Photos are still welcome though, so we can help you figure out what you're seeing.
