............Pilot Wheel Roulette chips you showed in your scan and the ones I have in my collection.

The first 3 chips - I believe were probably used at Harveys - Notice the "open space outline" of the wheel which is a unique design difference from all the other chips in the scans(yours and mine).

The next 6 chips, I purchased from another collector, who said he believed they were used in the Biloxi, MS area - possibly at the Broadwter Hotel back in the illegal gambling days.

The last 5 chips, I purchased from another collector who said he believed they were used at Harveys.

My conclusion - I believe the first 3 chips were probably used at Harveys and the other 11 chips with the "solid hot stamped wheel" are "Generic" but may have been used in several different Casinos and private Clubs over the years (maybe even Harveys !!) .

With no name or real recognizable logo these chips are really hard to pin down especially 50 years after they were in play.

Take care,
