These Johnson Matthey gold bars have world-wide recognition and are well known in the US for their reliability in the gold bullion investment market.
Johnson Matthey Gold Refiners. Johnson Matthey operates in more than 30 countries and has almost 9,000 employees. The refining of gold and the manufacturing of gold bullion bars and other precious metals takes place in two large refineries in North America. Johnson Matthey Limited is located in Brampton, Toronto and Johnson Matthey Inc is located in Salt Lake City, Utah. Both are wholly-owned subsidiaries of Johnson Matthey Plc which is a British multinational precious metals company located in London, England. It is listed on the London Stock Exchange and is a component of the FTSE 100 index.
The History of Johnson Matthey. The company dates back to 1817 when Percival Johnson started an assaying business when he was just 25 old. He was joined by George Matthey in 1851 when they became official melters, refiners and assayers to the Bank of England. Gold bars were produced by Johnson Matthey in England since at least 1852 and until 2004. As JM produced such a large quantity of gold bars for more than 150 years from their refineries in the UK, these historic gold bars are still extensively held and actively traded world-wide.
Johnson Matthey USA Operations. The Johnson Matthey Group has been operating in the United States for more than 90 years under several names and as Johnson Matthey Inc since 1980. In 1983 they established a new refinery in Salt Lake City because of the revival of gold mining in the USA and are now the foremost refiners of newly extracted gold in the United States. From 1971 to 2000 the company was the largest producer of gold bars minted in North America.
The Production Of Gold Bars. When the Salt Lake City refinery commenced production in 1983 they issued a range of 3 gold bars weighing 100 oz, 400 oz and 1000 grams (32.1507 troy ounces). The Johnson Matthey Group international trade mark (the geologist’s pick and hammer) was applied to the 400 oz market bars and the double oval logo with “Johnson Matthey – SLC” around the 9999 assay was depicted on the 100 oz and 1000 gram bar. There was a 5 figure serial number from 1983 but this was changed in 2005 to accommodate a 6 figure serial numbering system.
Good Delivery Bars. In 1989 the Salt Lake City refinery began manufacturing 400 oz “London Good Delivery Bars” therefore there was a change to the certification mark on this bar to include a reference to “USA” and again in 1990 to reference Salt Lake City (SLC). The acceptance of gold or silver bars as “Good Delivery Bars” is set out by The London Bullion Market Association (LBMA).
Historically the members of the LBMA compiled lists of assayers and melters whose silver or gold bullion bars would be accepted in transactions between each other without question. The LBMA’s list is now recognized world-wide as the quality standard for gold or silver “Good Delivery Bars”. They are typically used in the major international markets, gold and silver reserves of governments and the central banks.
