It's a spectacular looking non-denominational token (not intended to be used in slot machines). Difficult to get. It could not be purchased directly but was only given away for players points (quite a bit) or by buying certain items at the L.G. Smith Steak & Chop House located in the same Rennaissance Hotel as the Crystal Casino. The same hotel chain, which is, in turn, owned by Marriott, owns the Seaport Casino.

The current price is still less than I paid for it!
