10 oz Johnson Matthey 999 Fine Silver Bar (New) Country: United Kingdom Mint: Johnson Matthey Metal content: 10 troy oz Purity: 999 Fine Silver The Johnson Matthey brand may no longer be producing silver bars for investors, but that doesn’t mean that it has disappeared from the market altogether. While secondary market bars are still available to investors, the brand logo of Johnson Matthey is being revived by private mints on brand-new silver bars to provide investors and collectors with something to revel in. Note: Bullion products may have minor production imperfections—this is normal and expected for investment-grade bullion.
