Who make silver commemorative coins other than highland mint?

The highland mint makes medals or tokens, they do not mint coins. Only the U.S. mints can strike commemorative coins for the U.S.. The tokens and medals struck by private mints very rarely have a secondary market and people lose money for they pay to much. The value is usually in the amount of Silver and not an added value for being a collectible which it is not. Non coin collectors and those starting out make a big error in buying such products.
