About 50 years ago, Club Cal Neva in Reno and Tahoe added a 26 mm premium token to some of their slot machines. These were paid out of a separate mechanism and were redeemable for prizes. Franklin Mint struck the tokens in brass. The Mint also made some proofs of these tokens in bronze and others in silver and packaged them in a cardboard holder.

Here is one of the bronze proofs if you like the odd premiums that were used in Nevada casinos. The silver tokens were mostly melted in the 1970s when silver prices were high. This scarce bronze token is yours for $10 delivered in USA.
