I talked to my friend that I go to Vegas with and he said that he remembered these chips from the salon at the Mirage. We have both played it the room. He playes Roulette and I play 21. The minimum on the Roulette table is $500 on the inside and $500 on the outside. The maximum is $5000 on the inside and $100,000 on the outside. The last time he played there the chips had been changed. I think that was about three years ago. At least that was the last time I can remember playing there. The Mirage always kicked our butts!! By the way, the minimum on the 21 game is $500. I can't remember what the max was. I never won enough to test it. I hope this helps.
