Allan Myers dates the Diamond Club (Montauk, NY)from 1929-1939 and run by the Gambino and Anastasia families.

I'm sure I'm wrong again but the chips appear to be Burt chips. Jim B. is pretty sure Burt did not make smooth molds prior to late 1940s when they took over the USPC business.

Does anyone have, or know of, any other colors? Can these chips be anything but wheel chips?
