DESCRIPTION:
46g Prototype Round

We believe this 46g prototype round is a final production sample of the ascending diagonal Engelhard hallmark with triangle insert prior to its first 10oz application. It is a hand-cut piece and the dimensions of this hallmark match the reverse hallmark found on the reverse of last series 10oz pressed bars.
