Just keep looking. Over the past 15 years I've probably found at least 25 silver coins and a bunch of foreign coins in CoinStar machines. That doesn't sound that great but I didn't exactly work for them.
I found 7 of those silver ones since last summer but some were found in an unusual situation when I accidentally jammed the machine with a 12 gauge shell cap that was mixed in my clad bag. (don't forget that because it will get them to open up the machine and if you can schmooze a little, you might walk away with some good coins).
But just keep looking and when you least expect it you may get a nice surprise.
The only thing that bugs me (a little) are the funny looks I sometimes get when I pull those coins out. I think many people assume you must be broke or poor if they see you scrounging for coins, even with a metal detector.
Then again, I don't ever let it stop me. There's too much treasure out there to let a little embarrassment get in the way.
Anyway, better luck next time.
