Johnson Matthey Brand Silver Bullion Bars

Johnson Matthey is among the best-known private mints in the world. It is also one of the oldest, tracing its roots to 1817, when a London gold assaying company was founded by Percival Norton Johnson. After he was joined by George Matthey, the company, then known as Johnson Matthey, became the Bank of England’s Official Refiner & Assayer. Today, JM remains among the most reputable silver mints in the world, though the Johnson Matthey company’s scope has since expanded far beyond precious metal minting.
