Can someone please tell me why Nevada Chips are worth more than California chips?

I realize that as a whole, Nevada chips are more handsome than California, but not nearly are handsome as ones from the riverboat areas, Colorado and the northern states, so it can't be that.

I expect that California is second to Nevada as far as having the number of chips available for trade with Washington state possibly third. Does the fact that California has mainly card clubs as opposed to casinos have anything to do with it?

It appears to me that due to the smallness of some of these closed card rooms and the rareness of some of these chips, that some of the California chips would be worth at least as much if not more than many of the so-called rare chips of Nevada.

Maybe some of you "old-timers" (Gene, Mel, Greg etc.) could give me the anmswer.

Thanx, Paul
