Eastman lists a Top Hat Club in Holtsville, CA, east of el Centro. The chips he shows are HHR mold showing a Stetson with the word TOP over it in outline type. It operated in the early 1970's.

If the inlaid top-hat was used there as a poker chip, Larry doesn't mention it. The chip you picture are listed in Seymour as generic chips, PX-BQ, so there wouldn't be any way to trace a particular chip to use in any club.
