The coin shown is an old penny (or 'pinguin' in Irish). It's about twice the size of a quarter so I doubt if you got it into the washing machines! The half penny was the size of a quarter though. I actually used these coins as a kid in Ireland when they were legal tender pre-1971. Needless to say they are now without value.Originally posted by: joecav
