These are plastic promotional tokens from the Keely Smith-Louis Prima show at Cal Neva Lodge in Lake Tahoe. They are probably from the 1960s. Ten different, with the first three on row 1 showing both performers on one side and Cal Neva Lodge info on the other. The other seven have Louie on one side and Keely on the other. All say Good Luck.

These are listed in The Nevada Casino Promo Token Book but not every color. The set of 10 is yours for $50 including shipping to USA addresses.
