I believe this chip is Las Vegas. I have seen the posts & we can all take a guess at where this was.
My facts are:
DOts mold were this era, as the Eldorado CLub, CLub Bingo, & there is a Las Vegas Club & a new find of an El Cortez.
Are there many dot mold from CA?

MOre facts:
This chip was in the Phil Jensen collection!
He recieved it from Paulson in with old chips they used to sell in the 70's. Cost was just $10 a box for mixed chips. This chip was 10 cents! ONly one found. He later sold it to another collector dealer who I believe still has it.

There are pictures of this club! I will try to have them at the convention.
Bon Aire on Tropicana right off the strip has been there for years but I need to do further research. Bond Road became Tropicana Ave when the Tropicana opened or just before. April 4, 57 Trop. by Dandy Phil Kastello or something close to this name. Built for his girlfriend.

Oroville, CA. is a place that other Nevada chips have come out of. I have had George's Gateway Club & Senator Club chips that came from here.

Any input appreciated.
