There are two chip colors, blue and dark blue. I know at one time there was some thought that they could've been a HS-SILVER. I believe after looking at those chips, they were all on chips that had seen a fair amount of use. The others that were in great shape were found to have gold hot stamps.

We know they were used in the poker room and they hit the tables during the 70s. I've yet to find out much else, like which chip came first, what year they came out; you know, all the good stuff. If you happen to find some info, I would love it if you would contact me.

Scans are of my chips or from Chip Guide.
