Eureka casino in Blackhawk once planned to do a 54 chip set of the 54 different peaks in Colorado that are more then 14,000 feet high. In addition, each of the 54 chips were to have two different stackable sides and numbered and unnumbered non-stackables. This would have made 216 different chips. Luckily, it flopped after the casino couldn't sell the chips they made for the first 5 mountains.
