I received a copy of the current Poker Chip Co. catalog today. Includes several chip molds used by casinos, and also used for home games. They sell a variety of chips from lightweight (4 gram & up) chips to regulation weight (10.5 gram) chips. Molds include diamonds; dragon; mermaid; plus a relatively new "6-dice" mold chip.

The 6-dice mold reminds me of the newer "dieswirl" mold, except without the swirl.

Their website illustrates the various chip mold offerings, for those interested. Link is below.
