Johnson Matthey is one of the most respected and well-known precious metals brand. The company was originally founded in 1817 as a gold assaying business in London and would eventually grow to become the official assayer for the Bank of England in 1852. Today, 100 Gram Johnson Matthey Gold Bars are available to you online at JM Bullion.
Bar Highlights:
Johnson Matthey was founded by Percival Norton Johnson in 1817. The firm initially offered gold assaying services for the first three-plus decades of its existence. In 1851, George Matthey joined the company and it became known as Johnson & Matthey. In 1852, the firm was chosen as the official gold assayer of the Bank of England.
All of these 100 Gram Johnson Matthey Gold Bars are available to you with individual plastic sleeves for delivery. These bars are classic Johnson Matthey cast gold bars. Each one has a typical loaf style with markings that are stamped incuse into the surface of the bar. It is common for older Johnson Matthey gold bars of this type to have softer incuse stamps that result in incomplete inscriptions where the stamp did not fully form the letters or other markings.
Obverse design elements on the 100 Gram Johnson Matthey Gold Bar include all of the identifying hallmarks for the piece. These particular products were refined and assayed in the UK, as evidenced by the Johnson Matthey London logo at the top and the use of GRAMMES in the weight inscription, rather than GRAMS. The reverse field is blank.
Please feel free to ask any questions when you buy gold bars. JM Bullion customer service is available at 800-276-6508, online using our web chat, and via our email address.
