At work demoing a building we found an old safe no cash but a few coins dusty and laying in it. I said to my superior grab those coins this is an old building, we ended up finding a 52 and 57 rosie. Not a jackpot but a cool find none the less. We each got one.
There was credit cards and debit cards still laying on the bar from people that left them behind and a coupe drivers licenses, I doubt the person that owns it would really care he is a pretty prominent man in our community, and $3.00 worth of silver probably doesn't mean a whole lot to him.
