I've never had luck finding left behind rejected coins at Coinstar machines, though I always check... For some reason this week my luck changed. I found a handful of coins in one - consisting of some Canadian quarters, a Hong Kong 10 cent coin, some tokens, and 3 wheats including a 43 steel cent! Then a few days later I found a '53 dime in one. If I can't dig the silver I'm happy to get it this way instead I guess. And the steel cent is cool since I know I'll never dig one, at least not in recognizable shape.
