"H" MOLD (H.C.E.)-- 8 H's. H. C. Edwards and Co., NYC. Was a major supplier of Nevada chips, 1940's to 1968. The business was started in the 1920's [I own a 1929 H. C. Edwards catalog, but unfortunately it didn't include chips, just dice, cards, etc., although "checks" was one of the products listed on the cover] and was sold and broken up in 1984. Then Bazaar Supply/Berk Trading Co., Yonkers, NY, owned the mold and used it infrequently, but not for U.S. casinos. I am told that the mold was used in Europe at that time. In about 2004, Bazaar Supply/Berk Trading went out of business, and Atlantic Standard Molding/Poker Chips Online bought the mold, and although it is not yet shown on their web site, it is used today by ASM for home poker chip sets, but not for casinos..........Mark Lighterm has obtained some of the H C Edwards Co. shipping-chip hot-stamp records and has put them on two CD's ($15.00) and in an H.C.E. book. E-mail him at mlighter@bellsouth.net .....Club 36 chips are unattributed in some works, but the Richard Edward Staeffler Memorial California Card Rooms web site attributes them to club at 3628 University Ave, San Diego CA (1974-77). ... ..... As of October 2015, the mold is still being produced in Maine at Classic Poker Chips company, a company that took over from Atlantic Standard Molding in 2013-2014. All their molds can be seen here. The mold is licensed for use in Nevada as of 2014 onwards.
