I did some checking and the chip offered in the sale link posted by Chris is not only the same chip that I sold on eBay, it is THE chip I sold on eBay. The seller of that chip is the same as the one that bought two from me.

I'll also add that if that chip is R-9, I had more in stacks in front of me at the tables last summer when the fish were biting than are known to exist in the whole world, not to mention what I sold/traded last summer.
