We have $25's and $100's in Colorado. When gaming started several of the casinos had a rack or two of $25's. They use them to "color up" (ie count your winnnings) when you leave the table. I suspect we had a good salesman from Chipco! Only one of the early casinos had a $100 (The Gilpin). To the best of my knowledge, the Gilpin has never put their $100's on a table. Today there are 6 casinos with $100's in Colorado. Only Fitzgeralds actually has a live $100. They use it for the big wins on their 3 card poker table. JP Mc Gills, Bronco Billy's and the Imperial all have $100's. Their $100's were made to "maximize" profit from chip collectors. Richman also has a $100 that you can only get if you win 1,000 hand paid jackpots. This chip is given to slot players!
