This page contains our current information on 50oz class Engelhard silver production bars and Legacy Ingots. The Engelhard 50oz production lineage closely followed the stamping placement and style of earlier 100oz bars, throughout both US and Canadian production runs. Engelhard 50oz bars, in general, are actually quite rare, with less than 13,000 examples produced spanning over two decades. Since they are categorically larger commercial bullion bars, it is likely that a high percentage of these bars have been melted over the years.

Mid Hallmark | [999+] [Serial Number] [Hallmark in Elongated Octagon] [50•000] [MFR] | Cast Finish | 4th series 50oz ingot in MFR variation.
