I too, collect mold types and manufacturing variations. I have your two types and a third one that is smooth, no texture in the molding.That blue one also has a wider ring between the tri/clubs and the center area of the chip. The Clubs also have straight stems, not flared out at the bottom like the other two chips. Like yours, my middle chip has the injection nibs on one side of the chip. The other two have no injection marks of any kind. All are nice heavy clay/ composite chips. Has anyone ever made the distinction between clay composite, plastic composite and everything in between? What is the clay in clay chips???????
