I certainly couldn't propose 10, but I think one would be a chip I have never seen. My wife and I were shown a die at the show, I believe it was Bill Judge or Mike Spinetti. I just didn't get his name. It was from the NORTHERN CLUB and he said it is an example of 3 known. The club was one of the first in Vegas. Now, I would think a chip from there would have to be in the list.
