Hi Pete, there used to be a casino called Kactus Kates out by the Cal/Nv border on I15. It was owned by the Primm group. It was a very small club, just North of the Primmadonna, nowadays, Buffalo Bill's sits there. I believe, but I'm not exactly sure, that it closed up about 10 years ago. Your chip should be worth a few bucks.

Have a good evening, Dan
