Johnson Matthey

Johnson Matthey

Johnson Matthey is a historic name in precious metals refining and bullion, long recognized for quality and trusted hallmarks. Established in the 19th century, the company produced investment grade gold, silver, platinum and palladium bars and rounds that became staples for U.S. stackers and coin collectors. In 2015, Johnson Matthey sold its precious metals refining operations to Asahi Refining. New Johnson Matthey branded bullion is no longer produced, and existing bars trade on the secondary market.

Collectors and investors seek Johnson Matthey bullion for its brand recognition, consistent fineness and distinctive stamps. Legacy products include 1 oz, 10 oz, kilo and 100 oz silver bars in both poured and pressed styles, along with 1 oz and 10 oz gold bars and select platinum and palladium issues. Many bars carry the classic JM logo with crossed hammers, fineness, weight, an assayer stamp and a unique serial number. Smaller gold bars were often sealed in assay packaging. Vintage poured 10 oz and 100 oz silver bars are especially popular for their character and limited availability.

Today, Asahi Refining operates the former Johnson Matthey facilities and continues to produce Good Delivery bars under the Asahi brand.

Johnson Matthey bullion remains widely liquid on the secondary market, and some items may carry collectible premiums depending on era, minting style and condition. As with any physical metal purchase, compare dealer prices and premiums before buying.
