Charles Chew owned the Cosmo Club 1956-1966 in Reno. His widow and son met with Dwayne Kling and Clint Hubbard in Reno on Sept 21, 2004 and identified the chips as being used at 222 N. Lake St., just around the corner from the Cosmo. That location was the Happy Buddha, but these chips were used prior to it, sometime before 1958. They will be in the next Chip Rack, 10cent E4161, 5.00 E4162, 20.00 E4163. That's all I have, Doug in Kingman, Az.
