Can't find out what casino this belongs to. I want to make a home for it in my collection other than in the "Unknown" section. It is silver in color. On one side, it has printed in an arch over the top half "FOR USE BY PLAYER ONLY" and printed in an arch on the lower half "NOT LEGAL TENDER" and has a large $1.00 in the middle. On the other side, it has printed in an arch over the top half "FOR USE IN CASINO ONLY" and printed in an arch on the lower half "NOT LEGAL TENDER" and has a large "1" in the middle with the letters "one" printed across the middle of the "1". I would appreciate any help anyone can give. Thanks......Royce
