Rick,

2 of the 3 chips are listed as unidentified in TGT and a third is as Don noted a Golden Nugget Roulette. If you are looking for one book to identify all chips I would suggest The Gaming Table Over 16,000 chips are noted with information about locations, dates, and molds for chips from all over the world. Although it is not a priceguide, it is an invaluable tool to identifying chips.
