Design & Liquidity
Johnson Matthey gold bars typically feature a standard design. The obverse prominently displays the Johnson Matthey "JM" logo, often accompanied by crossed hammers, along with the inscriptions "JOHNSON MATTHEY ASSAYERS AND REFINERS," "FINE GOLD 9999," and "1 OUNCE TROY." Each bar usually includes a unique serial number for authenticity. The reverse side often showcases a repeating diagonal pattern of the JM logo and/or pickaxe icon, though designs can vary, with some later iterations having a blank reverse.
While Johnson Matthey ceased its gold and silver refining operations in 2015, selling its precious metals division to Asahi Holdings, Inc., the secondary market for these bars remains exceptionally strong. Johnson Matthey bars are highly sought after by both investors and collectors, frequently commanding a premium due to their historical significance, the brand's enduring reputation for quality, and their increasing scarcity, making them a desirable 'vintage find'.
About the Mint
Johnson Matthey, a name synonymous with excellence in precious metals, traces its distinguished origins back to 1817. Percival Norton Johnson founded the company in London as a gold assayer, swiftly building a reputation for meticulous standards. In 1851, George Matthey joined, leading to the company's full name, Johnson & Matthey. Over more than 150 years, and for two centuries in total, Johnson Matthey established itself as a global leader in refining and fabricating gold, silver, platinum, and palladium.
During its active period in bullion, Johnson Matthey's gold and silver bars were considered a standard for privately minted precious metals. While they are now a multinational speciality chemicals and sustainable technologies company, their bullion products remain their most recognized contribution within the precious metals investment community.
An interesting historical fact is that in 1852, Johnson Matthey was appointed as the official assayer and precious metals refiner to the Bank of England, a testament to their unparalleled accuracy and trustworthiness. Furthermore, the company was responsible for manufacturing the first standard meter and kilogram in a platinum-iridium alloy, which continue to serve as international reference standards today. Another noteworthy point is their pioneering work in developing the world's first autocatalyst in 1974, showcasing their broader scientific contributions beyond bullion.
