Pretty unusual sample from Nevada Coin Mart in 1991. It's one of those that offsets metal from one side to fill a design on the other side. In the scan, the recessed side is shown on the right. They also did this with the image of a US dime on a sample. NCM's web page hasn't been maintained in 10+ years so I take it they have either merged, or gone out of business.

Notice the design on one side has small images of six actual slot tokens made for Nevada casinos. The MGM token even has a date!

Also unusual is this sample has a $20 denonmination. It's not clear whether this was for credit towards a token order at the show, or whether it was for free-play at the Tropicana where the exhibition was held.

Got this from a casino exec who used to work in Reno for Caesars, and later for Peppermill.

Sorry, no extras to trade.
