Jim, Jerry Birl, the roulette chip guru, lists 18 known designs and 7 colors with possible total AC Playboy roulette chips 126. I have 79 different and looking for more. It is believed that maybe not all chips were actually used. For example, 18 different designs would mean 18 different tables in operation. A few people that I know that worked at Playboy don't remember that many games operating at the same time. One person remembered maybe 14-16 games operating. Maybe there was a time that they may have changed out the whole non-value chip bank on a table because the chips were worn and beat up. That would account for the extra designs. I hope this helps.
