Today Metalrex is a highly sought after refiner for both vintage silver bars and vintage gold bars. Perhaps its because there are very few silver bars of Nevada origin around. An undisputed favorite of Metalrex collectors is the ~2.5o oz bar that is actually shaped like the state of Nevada. These always bring an outrageous premium over silver spot prices.
