Those are some nice tokens. If you have a lot of them, it would be nice to put them in a display case and show them to your friends. My partner and I show our finds to local clubs in the area. It's a good way to promote our great hobby.
The "mints" token is a jackpot token from a small countertop slot machine, or "trade stimulator," of the 1920's-40's. The idea was that the tokens could only be exchanged for merchandise, not cash, thus getting around anti-gambling laws. Of course, just the opposite was the case.
