This is a strange one. The half dollar tokens Harolds Club had made in the sixties are all brass. This one is silver colored and I'm assuming it is not brass;probably Franklinium of some kind. It's in an orange proof FM holder which shows up as color streaks in my scan. ID on the cardboard holder is "Solid Franklin Brass/Proof/HGT-46". Marking on the reverse is "Solid Franklin Brass Proof Quality 2600 and Mint Quality 20000". Marking on the holder indicates the token has partial reeding but the token in the holder has plain un-reeded edges.
The shiny fields indicate to me that this is a Proof strike. Diameter is 1 1/4" which is correct for a half dollar.

This proof in the orange holder can be yours for $10, personal PayPal.
