They are not Western Club, LV. Made 13 years before it opened.
They may never have been "Used" at Western Club in Gardena.
They were sold to other buyers.

From the TR King records and David Spragg.

T.R. King bought the entire rack back from the Western Club in Gardena, CA in 1952. They resold some to at least 5 different buyers. 100 .25 went to Las Vegas, no casino name. No .10 left CA.

Some of the $1's were found in the vault at The Horseshoe a few years ago. So all but the .10 were in Las Vegas, probably downtown. My guess is not the Western as it didn't open until 1965. The chips were shipped to Vegas in 1952.
