Put one up on eBay and test the waters. If it goes for $10 you know that there is interest. If it sells for $1 you know that there's not much interest.

Being a WI Indian casino collector, I can't even find some of the older chips, but since there is little interest, when I do, they are not as expensive as an equally uncommon AC, Las Vegas, or Colorado chip.

Demand drives the prices, not rarity. Many hard to find, Tribal casino and interesting chips can be found as bargains. The image below is an example. Not in any CA guide or list.

So far I have sold three on eBay, all to people who write CA card room guides. Interesting? But no demand...
