I realize this is a long shot. Found what I think is a play coin but unsuccessful in interweb searches. There’s an F and an M on the back and it doesn’t flip correctly like a coin. Found at a 1910 house. Any help appreciated.
Definitely play money. The FM on the back stands for something like Fun Money or Fun Munny. Here is a good link for the ID of these: http://rfc33.tripod.com
