I was always fascinated with Mercury dimes , would keep every one of them I would get in change . Still have some from quite a few years back . Seeing yours made me take a look at eBay , there are some on there in excellent condition .
Years ago I would now and then go to the bank and get rolls of quarters and dimes . For a while I was finding quite a few Mercury dimes as well as old quarters in each roll I would get . Probably would not have much luck doing that today .
