The Engelhard Corporation is known for producing precious metal products that have become widely respected among collectors and investors. The 10 oz Silver Engelhard Bar is one such product, often sought after for its silver content and trustworthiness in brand. While the design on these bars may vary because they have been produced over many years and in different styles, each bar is stamped with the Engelhard name, weight (10 ounces), and purity (.999 fine silver). Due to their varied designs and discontinued production—Engelhard ceased production of silver bullion products in the late 1980s—they also carry a collectible premium and can be considered semi-numismatic.
