I’m almost certain the coins I have aren’t going to be worth much, but it’s worth a try. My mother and father owned a small country store from the mid 1960’s til the late 1990’s. He always kept certain coins. My father passed in 2015, these are just a few of the coins I found stored away in small samsonite case. There are several JFK half dollars, and some international coins. Maybe I will get extremely lucky and you will respond with some good news. ?
