...don't hesitate to purchase either or both of the the two price guides available. The Chip Rack 10th edition by Knapp, Myers, Wheelden, which is exclusively Nevada or The Official U.S. Casino Chip Price Guide 3rd ed. by Campiglia and Wells which also has CO., SD. the Riverboat States and New Jersey as well as Nevada. Although the initial purchase price of these guides might seem to cut into your chip collecting budget, the return is huge. Lots of educational material for the new collector and valuable resource for every level of chipper, we all give ours a regular workout on a steady basis.
