Johnson Matthey

Back in 1817, Percival Norton Johnson created a gold assaying business in London, which became Johnson Matthey after he partnered with stockbroker George Matthey in 1851. In 1891, JM became a limited company, and by 1942 company shares appeared on the London Stock Exchange. If you haven’t heard of Johnson Matthey before, you might be interested in knowing it became an even bigger success after creating the world’s first catalytic converter back in 1974. In 1976, JM won the Queen’s Award for Technological Achievement for the catalytic converter creation.

In the 1970s and 1980s, JM became popular due to silver bars that it had created. Instead of focusing on precious metals as it did in the beginning, JM now focuses more on the manufacturing side of things, primarily in the automobile industry. JM manufactures catalysts and special chemicals and also is involved in improving technologies to help lessen the environmental impact of emissions. There is still some refining and distribution going on, especially in silver, gold, and platinum precious metals.

There is a huge demand for silver these days and that allowed JM to begin producing more silver, just like back in the 1970s and 1980s. The demand was so big that the company re-released the JM 10-ounce silver bars back in 2014, which sent both investors and collectors into a buying frenzy. All of Johnson Matthey precious metals come with the “JM” stamp, which includes the hammers and the .999 purity label.
