These are generic arcade tokens, stock tokens. I was in the coin op business and these came in diameters larger or smaller than a quarter. I believe there is a regulation that when producing tokens they cannot be the same size as a quarter. Coin accepters are modified to accept these and sold as bulk tokens.
I had a buddy that used to call them divorce tokens , on one side you have "freedom and the other side is no cash value" , kinda true.
