Any Token/Store Card Experts Out There?

First off, please excuse the pix if the sizes are too big or small. This is only my second post on CT. I've had this token or store card or (?) for 50 years, and don't know a thing about it. Looks to be copper, and it's one inch in diameter. Any info would be greatly appreciated, even educated guesses. Thanks in advance.

May have been made by S. G. Adams Stamp & Stationery if everything on the back looks right. the G may look like an C

More pictures, Looks like the same style stamps used by S. G. Adams Stamp & Stationery but they shorten it on your token.
