In one of the previous posts the "N" mold was mentioned and I thought I had a chip with that mold. So I started looking thru my chips but could not find one. I did however find two chips with unusual molds. The chip on the left has no mold. In fact the "inlay" is really made just like the inserts and is cast with the rest of the chip. Who makes this type of chip and is there a name for this type of mold? (or lack of a mold)The chip on the right I always thought was a Raised Circle mold but notice that there is a second inner circle or bead in the hot stamp area. Is there a name for this mold?
