10 oz Johnson Matthey Silver Bar

The 10 oz Johnson Matthey Silver Bar

The 10 oz Johnson Matthey silver bar is a legacy product from one of the most historically significant precious metals refiners in the world. Johnson Matthey exited the precious metals refining business in 2015, selling its operations to Asahi Holdings of Japan. No new Johnson Matthey silver bars have been produced since that transition, making every bar on the market today a finite-supply item from existing dealer and collector inventories.

Johnson Matthey's history in precious metals refining spans over 200 years. Founded in London in 1817 by Percival Norton Johnson, the company became an assayer to the Bank of England and held LBMA Good Delivery accreditation throughout its refining career. The 10 oz silver bar was one of the company's core retail products, produced at their facilities in both the UK and North America. These bars are struck at 999 fine silver with individually stamped serial numbers and the distinctive JM hallmark.

The closed-supply status of Johnson Matthey bars gives them a modest collector premium above generic or current-production bars of the same weight. This premium is not dramatic, typically adding a few percentage points above comparable products from active refiners, but it reflects both the historical significance of the brand and the certainty that no additional supply will enter the market. For buyers focused purely on silver weight at the lowest cost, a current-production bar from a refiner like the Royal Canadian Mint or PAMP Suisse will often be cheaper. For buyers who appreciate the provenance and finite nature of a legacy refiner product, the Johnson Matthey bar holds distinct appeal.

Asahi, the successor to Johnson Matthey's refining operations, now produces its own branded bars using the same facilities and refining expertise. Asahi bars are widely available and carry LBMA accreditation, but they do not command the same secondary-market recognition as the Johnson Matthey name.

10 oz Johnson Matthey Silver Bar Specifications

Johnson Matthey produced 10 oz silver bars in both pressed (minted) and poured (cast) formats across their production history. The minted bars carry a cleaner, more uniform appearance with sharp stamping of the JM logo, weight, purity, and serial number. The cast or poured variants have a rougher, more hand-finished look that some collectors prefer for its artisanal character.

Both formats contain the same 10 troy ounces of 999 fine silver. The minted versions were produced in greater numbers and are more commonly encountered on the secondary market. Cast bars, particularly older vintages, may command a slight additional premium from collectors due to their relative scarcity.

The JM hallmark on these bars was one of the most trusted stamps in the precious metals industry. Johnson Matthey served as an official assayer to the Bank of England, a role that required maintaining the highest standards of weight and purity verification. That institutional reputation persists in the secondary market, where JM bars are accepted without question by dealers worldwide.

Tax Position for the 10 oz Johnson Matthey Silver Bar

The discontinued status of the Johnson Matthey bar does not affect its tax treatment. Silver bars are taxed based on their metal content and purity, not on the manufacturer's current production status.

United Kingdom

Silver bullion is subject to 20% VAT on purchase in the UK. Johnson Matthey silver bars carry the same VAT liability as any other silver bar. On disposal, gains are subject to Capital Gains Tax at 18% or 24% with a GBP 3,000 annual exemption. Silver bars lack legal tender status and therefore receive no CGT exemption, unlike 1 oz silver Britannia coins.

United States

Most states exempt investment-grade silver bullion from sales tax. Johnson Matthey bars at 999 fine qualify as investment-grade. Silver bars from LBMA-accredited refiners meeting 999+ fineness are eligible for Self-Directed IRAs, though the buyer should confirm specific custodian requirements. Capital gains are taxed at the collectibles rate of up to 28%.

Canada

Silver at 99.9%+ purity is exempt from GST/HST. The Johnson Matthey bar qualifies. Capital gains use a 50% inclusion rate.

Australia and New Zealand

Investment-grade silver at 99.9%+ purity is GST-free in Australia and GST-exempt in New Zealand. The 999 fine silver meets these thresholds. New Zealand has no capital gains tax, and Australia offers a 50% CGT discount for assets held longer than 12 months.

Singapore and Hong Kong

Singapore exempts qualifying silver (99.9%+ purity) from 9% GST under the Investment Precious Metals scheme. Hong Kong imposes no sales tax, import duty, or capital gains tax on silver.

Johnson Matthey vs Other 10 oz Silver Bars

The Johnson Matthey 10 oz bar competes with current-production bars from sovereign mints and active LBMA refiners. Its discontinued status creates a different value proposition from bars that are still being manufactured.

Against the 10 oz Britannia silver bar from the Royal Mint, the Johnson Matthey bar trades on legacy reputation rather than current production advantages. The Britannia bar is a current sovereign mint product with consistent availability and modern packaging. The JM bar offers historical provenance and finite supply. For pure silver accumulation at the lowest premium, the Britannia bar is typically the more cost-effective choice. For collectors who value vintage refiner bars, the JM carries an appeal that current products cannot replicate.

Against Asahi 10 oz bars, the comparison is direct, since Asahi acquired Johnson Matthey's refining operations in 2015. Asahi bars are produced in the same facilities with the same expertise, and they carry LBMA accreditation. The key difference is brand recognition: the Johnson Matthey name is established across decades of precious metals history, and Asahi is still building its market presence among retail buyers. JM bars generally command a modest premium over equivalent Asahi products.

Against the 10 oz PAMP Suisse bar, the two products serve different buyer motivations. PAMP offers the Lady Fortuna design, VeriScan authentication, and active production with guaranteed availability. Johnson Matthey offers institutional heritage, LBMA provenance, and scarcity. PAMP bars typically carry a higher retail premium driven by brand recognition, particularly in European and Asian markets. The JM bar's secondary-market premium is more modest and driven by collector interest rather than branding.

For investors building a core silver position, the choice between a JM bar and a current-production alternative comes down to whether the historical provenance and finite supply justify the few extra percentage points in premium. For pure cost efficiency, current-production bars from the Royal Canadian Mint or Royal Mint will generally offer better value.
