Hey Greg,

If the chip you are asking about is the same as the one in the image below (top row, second in from the right), then I'm sorry to say, that chip is (was?) a readily available chip - produced by Paulson. The last time I was in Vegas, the chip is available at the Paulson store for $0.65 each...

I'm heard two stories about this chip.
First that it was produced for a casino, yet the order was never picked up.
Second that it is a fantasy chip...

Sorry for the bad news...

Dick
