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.
Today, Engelhard Corporation is now owned by a German chemical manufacturer. The international BASF company bought Engelhard for $5 billion in 2006.
