Johnson Matthey: frequently asked questions

Johnson Matthey built its precious metals reputation as an LBMA-accredited refiner and a leading producer of investment gold and silver bars, particularly in North America where it was among the largest minted bar manufacturers from the 1970s through to 2000. The company has since exited consumer bullion, selling its gold and silver refining operations to Asahi Holdings in 2015. It now operates as a speciality chemicals and sustainable technologies business.
Johnson Matthey is headquartered in London, United Kingdom. The company was founded in 1817 at Hatton Garden, London, and operated refining sites across the UK as well as in North America. Its current head office is in London; however, its precious metals refining businesses were sold to Asahi Holdings in 2015.
Yes. Johnson Matthey ceased retail and investment bullion bar and round production in 2000, retaining only wholesale LBMA Good Delivery bar manufacture thereafter. In 2015 it sold its gold and silver refining operations entirely to Asahi Holdings for $186 million, and LBMA Good Delivery accreditation transferred to Asahi at that point. Bars in circulation today are all secondary-market pieces.
Johnson Matthey bars, particularly the 100 oz and 10 oz sizes produced during the 1970s to 2000 period, have acquired secondary-market appeal among stackers who seek vintage refinery bars. Because production has permanently ceased, supply is finite. They typically trade near spot with modest dealer friction, appealing to buyers who value the LBMA heritage and the brand's documented quality history.
Check the physical stampings: weight, fineness (.999 fine for investment silver bars), the JM pick-and-hammer monogram, and serial number. Serial number formats varied by era and facility (UK vs North American bars differ). There is no active central JM serial database, as production ceased. Weigh the bar against its stated weight, check dimensions against published specifications, and purchase from a reputable dealer who can trace provenance.
