Hiya deb, I don't have a guess so I guess no prize for me! Not Harolds Gun Club, they used HCE chips there. Must have been a pretty cool place out there at Pyramid Lake, lots of high roller action. They used to load the chips including regular high denomination Harolds Club chips into a bunch of Cadillacs in the alley behind the "store" along with some shotguns and run them out to the Gun Club whenever they had shooting competitions.

I've got a Clover Club from Hollywood in small key but it has the denomination w/o dollar sign inside of a three leaf clover...perhaps The Gaming Table has your chip listed.
