Below are some order cards and ledger entries for your six chips. 3200 chips sold in 1961, by the San Francisco Card Company. Those chips being sold to someone in Oakland, across the bay, makes sense.

What is interesting is that the exact same inlay is used on 1000 gray and green chips that were sold one month later in 1961 by the Bowman Equipment Co. (Chicago, IL).

We don't know the edge mold type from the order card, but it was probably plain mold/crest and seal, or possibly on Bowman's proprietary Wave edge mold design. I don't know if Bowman, however, was using the Wave mold that late. They generally used it in the 1930s and 1940s.

Strange that the two sets of chips were sold 2000 miles apart. Both distributors tended to have regional sales. Does anyone know what the translation of the inlay is? If anyone can translate any of the inlays, I can add that information to the ChipGuide entries, which might help in tracking down where they were used.
