I'm in the habit of not paying attention to the coins I receive when I get change back from a purchase. I take note of the bills but rarely notice the coins. After all, how big of a mistake is going to be made with the coins? What brings this up is: I got stuck with a Canadian quarter. It won't work in vending machines because it is smaller than a real quarter and I wouldn't feel right about trying to pass it on to someone else. I guess I could make a trip to Canada to spend it, but that's an awful long way to go for 25 cents. If anyone is in need of a Canadian quarter, I could make you a deal on it, but I'm not paying postage to send it via USPS.
