I have been looking for these chips for a very long time. Crystal Mountain Casino was the "tent" place that preceded the Red Hawk Casino just out of Placerville, CA. They were only open for a very short time - they had problems with the neighbors because the only access was via some narrow residential streets. The Red Hawk solved the problem by paying for the state to put in new off ramps from the Highway 50 Freeway. These chips have been pretty hard to find but I suspect they are out there in quantity and will show up one of these days. I am sure happy to get the compete set.
