Each of these one hundred ounce Johnson Matthey Silver bars contains 100 troy ounces of pure 0.999 Silver. Additionally, these silver bars are cast into shape, i.e. molten Silver is poured into molds and allowed to cool. This process results in silver bars that have a rustic appearance and a slightly tarnished surface, reminiscent of antique products that some people prefer compared to the smooth finish of mint bars.

The top of the obverse features the famed Johnson Matthey name and logo, exquisitely imprinted onto the metal. At the bottom, stamped into the Silver is the purity and weight of the Silver in the bar – ‘100 oz’ and ‘.999.’ Consequently, this minimalist design ensures that the focus remains on the pure Silver that was used to create this bar.

Johnson Matthey was founded by Percival Norton Johnson in London, England in 1817. The company began as a gold assayers shop under Johnsons guidance, and grew to Johnson Matthey after George Matthey joined the business in 1851. One year later, the business earned status as an Official Assayer & Refiner to the Bank of England.

Today however, Johnson Matthey is no longer involved in the precious metals marketplace. After more than 150 years in the industry, the company sold its silver and gold refining business to Japans Asahi Ltd. As a result, these 10 oz Johnson Matthey Silver Bars are some of the few remaining JM products available for purchase on the secondary market and highly collectable.
