The Nevada Club and Money Tree chips are available in huge quantities from dealers and have no particular collector value. This is true of many (but not all) of the older Reno chips which were not destroyed when the clubs closed or went bankrupt.

I believe the Harrahs yellow dollar brass-core chips are still used on the tables from time to time. They were hoarded in very large quantities when the brass-core rack was removed from Harrahs several years ago.
