Johnson Matthey, founded in London in 1861, is one of the world’s oldest and most famous precious metals refiners. At one time, Johnson Matthey operated one of the biggest precious metals refining groups in the world, with operations in the UK, US and Canada.

These Johnson Matthey 1 Kilogram cast silver bullion bars have a silver content of 99.9% pure silver.

In 2015, Johnson Matthey’s gold and silver refining operations in the US and Canada were acquired by the Japanese group Asahi Holdings, meaning that Johnson Matthey’s classic cast silver bars are no longer produced. For silver buyers, this adds a certain collectability to these particular silver bars. The JM cast bars are difficult to source, and once BullionStar’s current stock is sold out, it may not be possible for us to replenish. Stack these silver bullion bars today.
