Wrong Coins

I was just thinking about this... has anyone ever been cheated on their coins? I know that you can get some foreign coins super cheap, and I'm surprised that I've never gotten a roll stuffed with foreign junk in place of halves or quarters.

I did talk to a cashier who said that she once got a customer who paid in rolls of dimes that were actually full of cents with the rims filed off. Funny how some people will spend so much time to cheat people out of a couple bucks.

I almost every week get rolls of quarters with nickels in side, one or 2 nickels in a roll.
