Yes, the Hardrock Biloxi $100 exist, however you will have to find a collector willing to depart with them, on 11 different was issued in 2007 none since other than house chips, I only have the $5 and $25 all of them. to the best of my memory, the casino destroyed their remaining inventory several years ago with about 100 or less of each that left the casino, neither of these or the $5 or $25 are no longer redeemable, I knew of one collector who had all including the $100's, now deceased, daughter has collection and not willing to sell
