Casinos don't want GPI selling any chips to the home market ever. Never mind that ceramics and plastic chips could be easily duplicated. Especially ceramics, with all the Chinese manufacturers. RFID and security features are almost impossible to duplicate, so if a casino does those right, there isn't much danger of fakes. The problem some casinos had in the early 2000s is they had RHC chips with basically no security features, and creative counterfeiters turned $1 and $5 chips into really good $100 fakes and made bank. The casino market dwarfed the home market, so GPI just shut down the home market, with a few exceptions here and there for about 10 years.
I always thought the 40/41mm Paulson pro mold was a nice compromise, but those came and went very quickly. Paulson has all the BCC molds they could use too, but they simply mothballed all of those and shoved them in a closet.
