Here's one I've never seen before (first chip in the scan). Looks like it was a prototype because that's a small piece of metal in the chip for weight and the reverse is blank, like the plastic injection was an off center mistake. If it's indeed a new discovery, doesn't the finder get to name it? In that case, how about the "double G" (for Goodrich, of course!)
I don't collect molds, so I have this single chip available. I also have one each of the other "somewhat obscure" molds shown in the scan, the dieswirl, LHD 4-suit, and dollar sign. Drop me an email if you are interested.
