Each of these 100 oz Engelhard Silver Bars represents the roots of silver refining. While the modern investor will find silver bars finished as minted ingots and hand-poured collectible bars, there have always been cast silver bars for those interested in the pure investment value of silver. While most of Engelhard’s bars are cast silver bars, it is possible for a Secondary Market listing to feature minted bars as well.One of Americas original precious metal refiners was the Engelhard Corporation. The former Fortune 500 company was originally founded in New Jersey in 1902 by Charles W. Engelhard. He purchased the Charles F. Croselmire Company in nearby Newark, New Jersey and founded the American Platinum Works one year later. While the company originally focused on platinum smelting and refining, the selection of products grew over time to include silver and gold bars as well. These 100 oz Engelhard Silver Bars have a cast finish, indicating the silver was melted and poured into a pre-formed mold where it cooled before inscriptions were stamped into the bar. On the obverse of the 100 oz Engelhard Silver Bar, youll find the only engravings. Arranged horizontally across the bars obverse surface, the inscriptions include the Engelhard name across the top with the purity and weight at the bottom. In the center of the bottom inscription field, youll find the individual serial number for the bar in a six-digit numeric code. The reverse side of the bars feature no design elements. Cast bars are often left blank on the side that faces down in the mold as inscriptions are stamped into the exposed top layer of the bar. This is the side of the bar exposed while the 100 oz Engelhard Silver Bar cools. Today, Engelhard Corporation is now owned by a German chemical manufacturer. The international BASF company bought Engelhard for $5 billion in 2006.
