This is a unique and very rare poured and hand-stamped 50.13 oz bar. Made by Heraeus-Enright Refining Co., Inc. located in Newark, New Jersey. This vintage bar is very interesting in the fact that it is 999.5 fine. This fineness has not been used in several years as the 999.9 fineness is now in favor. The individual hand stamps are very strong and the bar is in excellent condition!
