This is the error version of the Harrah's Reno/Tahoe $2.50 chip - not a common chip but I have not seen any in paperweights. I have quite a few other chips, tokens and strikes in lucite - they are sort of fun - my wife likes them so much she won't let me sell any of them. There are a couple that I would sure love to get out of the lucite - pretty rare chips - oh well,,,
