Pretty cool chip Roy, I like it! Don't know anything about age or value though. These Hotel Riverside 25¢ NCV's were given out to arrivals at the Reno bus station. An incentive for gamers to stop in, I imagine you could use them for a bet at any table. These babies are all unused as TR King made them in 1970 and the operator of the Riverside Hotel casino went broke in '70 and shut the place down. Jessie Beck acquired the license and reopened the casino.
