Brian, the paragraph below is a copy of the explaination I currently have on ebay regarding these chips.

You are bidding on the blue "B" Cache Creek roulette only. This is the first offering and the first sight of these chips by anyone on this board. Cache Creek has a history of bringing out new chips on a one time only basis and anyone lucky enough to be playing in their weekly tournament has the opportunity to harvest them. I don't know if this is the case for these particular chips or not (the other 2 are in separate auctions.) The last time they brought out some new chips, it was for a one time event and only one person was lucky enough to get them--I didn't even save any for myself as I though I could get some more the following week and later found out I couldn't. At present, I have only 3 of these chips available. As usual, shipping is free of any extra cost.
