If it's these chips, Dick, they were later released to the collector market in quantity. There is also indication that the $500 was used as a live chip in another club for a short time (California if I remember right). Chips are seen in both notched and un notched form. This is one of the episodes that caused Paul-son to stop offering uncancelled chips to their retail customers.

I have some of these for sale if anyone needs them.
