Well last night I got surprised when some young kid around 17 or 18 years old came in and paid for his meal in cash and handed me this 1947 half dollar. Sadly it is polished heavily but its still nice.
Hope you got them on surveillance camera. The police may want a photo of the guy as it could have very easily been stolen. I know, I'm pessimistic about my fellow humans. LOL Seriously, I'd contact the local LEO and see if any home robberies have reported coins being missing.
Do we have camera's at the restaurant I work at yes. However unless its counterfeit or foreign we have to accept any form of cash and if a coin or dollar happened to be stolen our insurance will cover for the value of said coin or dollar.
