Canadian eh? It’s not uncommon for Canadian coins to be mixed in with ours when giving or receiving change. Most people just ignore it, if they notice at all, and carry on business as usual. I’m sure it happens more in northern states that are near the Canadian border than it does in the Deep South. A couple of days ago I noticed one quarter and two nickels amongst my change. (Technically the Canadians do not have “quarters, dimes or nickels” those are American terms. But many Canadians use those terms, referring to American and Canadian coins, because of the contact they have with our culture.) Several years ago I found a Deutsche Mark coin. That was highly unlikely, and now they have switched to the Euro.
