Hi Don... Years ago we decided to NOT include UV variations in the interest of keeping the book slimmer than the Manhattan phone book. The only ones we've included were the Luxor $1's.

Another decision we made at the same time was to not include Hat and Cane variations for chips manufactured after 1999.

While we do appreciate that The Chip Rack has a substantial influence on what and how people collect Nevada Casino Chips, there are too many variations, both real and imagined, to include everything that all collectors can find. We feel that we are as inclusive as possible, given the constraints on both our time and the printing limitations to which we must adhere.
