The obsolete Blue and Orange roulettes that I found from the High Roller table at the Mirage also have a slick finish. In fact they look like some one painted polyurethane or something on the chip. But that is how they came from Chipco. Strangely the black chips from the same table have the usual Chipco finish. Obviously the slick finish was not liked since those chips are not worn and the black ones have some table wear on them. I have all three chips available for $8 each or $20 for all three.
