The MGM Theme hotel started out life with one Eurppean roulette table that had acrylic jetons with denominations. The $10 blue chips, which were usually the lowest value in play, had at least 4 variations so the could be multiple players. This game was not very popular and was discontinued after a few months. Most likely it was the high minimums, but it was a single zero table so the players should have preferred it.

This was before the craze in roulette-collecting and not too many seem to have been saved. I've seen some of the blue chips with stripes or half moons sell at $60-80 at auctions. The $20 red jetons were serialized and even fewer seem to have been saved. I can't remember what the higher denominations looked like, but the big ones were probably plaques.
