I saw these chips, went ULP!!! and checked Gregs Riverboat book for value. Neither one was in the book. I saw Greg a few feet away so I asked him what he thought they were worth. I managed to get them for that price but when I showed them to Greg later he went ULP!!! He was quoting me the price for sample chips with the Chipco back. These are the real thing right off the tables. I still wonder how many sets got out.
