So I was at work today and one of the office people called me to the front. He says "here want these" and hands me a 2012 nickel, 2 2010 nickels, a 2007 nickel, an 05 dime, and an 01 dime all Canadian. He said a cashier took them as change and they can't deposit them. So I got 40 cents in Canadian money for free. I don't think there worth anything other then face value but was like cool free money.
