I have the chip shown in the scan. Chips with the same K are listed as "Private Game" LaCanada, Ca. 4 colors, including yellow, but no denominations. A K $1$ chip is listed in Larry Eastmans California guide as "Club Lido" Winterhaven, Ca. Armin lists that chip also with ID given by Eastman. My chip is K $10$ in yellow. Should I list it as attributed to Winterhaven, Ca. ?? or Unknown ?? or forget about it ?? Thanks for any insight. Doug in Kingman, Az.
