I have only a half dozen of the chips. Never saw before. Not in Hertel's illegal club chip guide. Not in The Gambling Table. But just now, an author of The Gambling Table ID'd the chip for me as follows: "The Wheel Club opened in Billings in 1927 and is closed.." The chip is a casino chip size 1-9/16." It has no rim mold design. It is a thick square-edge chip. Sharp gold hot-stamp.

Also look here for a list of recent Chicago and Montana illegals I picked up:
