If you go to the convention you should be able to find the RCC and SCC chips. If I remember correctly I have even found them in junk boxes since many do not realize that they are real casino chips.

I should really come to the convention some day.

The RCC $25 and $100 were controlled by someone within the casino employees. I suppose someone may have had some and sold their collection. The SCC are just way old!

Nice collection Dan Madrigrano
