Robert,

These are generic poker chips. Manufactured by the USPC Co. and others from the early 1900's to about the 1930's? Usually used for home poker chip sets although some illegal clubs used them. There are a lot of these on , often in multiple chip lots. Single chips usually sell for $2 - $5 depending on the letter & color. Some letters are very hard to find.
