Got these at the convention couple of years ago. The only reason I went there was to buy the books on gambling from Reno university instead of going through the hassle of the cars and human traffic I now order directly online with free shipping delivered to my house.

Any one interested can email me. I got two of the 5 and 1 token available.

I don't remember how they were used and played, notice the numbers on the chip - i.e., the snapper is 2 at the time they were using 6 different numbered chips (1-6).
