Engelhard 100-oz silver bars
Early extruded silver bars
Since the development of the physicals silver investment market in the early 1970s, Engelhard 100-oz .999 fine (99.9% pure) silver bars have been among the more popular silver bars because Engelhard Minerals is a major player in the precious metals industry. The first Engelhard silver bars were the poured 100-oz bars. As demand grew, however, Engelhard went to an extrusion process, which lowered manufacturing costs. The bar pictured is the first version of Engelhard extruded bars. A later form of extruded bar replaced this one.
The Engelhard hallmark, the description, and the identification number are recessed, having been stamped on the bars. Both styles of Engelhard extruded silver bars measure 5-7/8" X 3" X 1 and weigh 6.86 pounds on a bathroom (avoirdupois) scale. Because of their uniform sizes, Engelhard extruded silver bars stack and store easily.
Engelhard and Johnson Matthey are the two most highly respected names in the precious metals industry, causing many investors to ask for only Engelhard or JM bars. However, when Engelhard and JM bars are not available, investors can invest with confidence in other silver bars that have become readily acceptable in the silver bullion investment community. Those other silver bars include Academy silver bars, Sunshine Minting silver bars, Wall Street Mint silver bars Ohio Precious Metals (OPM) silver bars.
