According to the T. R. King order cards, the variants you have of those "B*G" chips were sold to the club owner, Frank Giovanni, in 1957.

The order card was missing from the 19th Hole listing, but I just posted it, and it will show up there tomorrow at midnight, Pacific time.

I'm a ChipGuide Admin for California. Can I upload your chips to the 19th Hole ChipGuide listing, and credit you?

Thanks,
Jeff
