I went to the Empress Joliet this afternoon and found the following:
C1 both long and short cane
C5 light red long and short cane
C5 dark red short cane
C25 long and short cane
Althought I am always suspicious of things I am told at casinos, the story I heard was that these are the old backup set with some new ones ordered to provide enough chips, hence the two red varieties. I think there may be two white C1 batches too but I sure can't distinguish them. They say that they don't have enough of the new C100 to put it out yet. We have these in stock and would be happy to sell them. I'm going by there again in two weeks if anyone wants one of the new C100's when they come out. I don't stock $100 chips.

PS - Sorry I don't have a scanner here to show the varieties. If there are requests to do so I can try to scan them Saturday.
