Found this Harrah's free drink "token" at a local coin show this morning. Made of heavy paper, 1 1/2" square. It appears to be double stamped on the reverse, "RC JUL 23 1965". I can't recall ever seeing one of these.

It's (make me an offer) or . I'll trade for any chip from San Francisco, inlaid single letter monogram chips in the PO-AA to PO-AZ style, or older advertising chips.

Thanks for looking.
