I have this $.25 chip from the Horseshoe Club in Gardena, California. I don't know much about it but it is a small crown mold and is the same on both sides. Both sides are shown. One side has partial gold hot stamp and the other side has the "gold" completely worn off.
According to Dick Staeffler's Guide, the card club opened in 1945 and closed in 1989.
I'm not a California chip collector but if you would like this for your collection, $3 gets it shipped to your home. Please email me directly if you need it.
