Johnson Matthey has a long and prestigious legacy - originally being founded in 1817 by Percival Norton Johnson, who initially started the enterprise as a gold assayer in London. The company was joined by George Matthey in 1851 and in 1852 the company was appointed as Official Assayers, Melters and Refiners to the Bank of England. The name of the firm was changed to Johnson & Matthey, then Johnson Matthey. The company head office is on Farringdon Street in central London. Johnson Matthey is considered to be one of the "top flight" of bullion bar manufacturers with a long standing reputation for quality and product integrity.

Johnson Matthey silver bars have been manufactured a numerous different sizes and featuring different designs over the years. The company is known to have made bars in sizes all the way from the large 1000 troy ounce "London Good Delivery" cast silver bars through 100 ounce (both minted and poured bars), 50 oz, 1 kilogram, 25 oz, 20 oz, 10 oz, 7 oz, 5 oz, 4 oz, 3 oz, 100 gram, 2 oz, 1 oz, 0.5 oz, 10 gram, 5 gram and 1 gram sizes.

Most of the company's bars feature simple designs including the logo, assayer's mark, serial number, bar size and purity - however the company has also made a few "art bars" including the popular "Apollo 1968" bar (which was made in the 1980's.) Johnson Matthey has also manufactured bars for other financial institutions, such as Republic National Bank of New York and Nerco Minerals.

The company logo appearing on the bars has taken various forms throughout the ages. Johnson Matthey's trademark official stamp in modern times depicts a "hammer and geologists pick" and this, together with the initials "JM" may be seen on the modern Johnson Matthey bars. However, some of the old bars cast in the UK featured an older logo - the "double oval" logo with the company name within it. "JMC" or "JMAC" may also sometimes be seen.

Johnson Matthey group has several companies in different countries which manufacture bullion bars - including Johnson Matthey Inc.(USA), Johnson Matthey Limited (Canada), and AGR Matthey (Australia) - and its refineries in these countries are accredited by the London Bullion Market Association.
