1g Johnson Matthey Gold Bar

A Heritage Refiner's Smallest Gold Bar

The 1g Johnson Matthey gold bar carries a name with deep roots in precious metals. Johnson Matthey, founded in London in 1817, was one of the most respected refineries in the history of the gold trade, holding LBMA Good Delivery accreditation and serving as one of the five members of the London Gold Fix for over a century. The refinery's gold bars were a benchmark product in institutional and retail markets alike.

Johnson Matthey exited the precious metals refining business in 2015 to focus on its specialty chemicals and catalytic converter operations. This means no new Johnson Matthey gold bars are being produced. Every 1g JM bar on the market today is existing stock, either dealer inventory or secondary market product. This discontinued status gives JM bars a mild collectible premium in some markets, though at the 1g size, the practical difference is small.

The bar itself contains one gram of 999.9 fine gold, sealed in a tamper-evident assay card with the Johnson Matthey hallmark, serial number, and purity certification. The JM brand remains globally recognised, and any reputable dealer will accept these bars for buyback. The LBMA accreditation that JM held during its refining years continues to support the credibility of bars produced during that period.

For buyers considering a 1g JM bar, the key question is whether the heritage premium is worth paying over a currently-produced alternative. A 1g Valcambi bar or 1g PAMP Fortuna bar can be verified through their manufacturer's current security systems, and supply is consistent. The JM bar offers a piece of precious metals history, but at the practical level, it contains the same gram of gold.

Johnson Matthey 1g Gold Bar Details

Johnson Matthey's history in precious metals stretches back to the company's founding by Percival Norton Johnson in 1817. The firm became an official assayer to the Bank of England and was instrumental in establishing London as the centre of the global gold market. George Matthey, who joined as a partner in 1851, helped develop refining techniques that set industry standards for decades.

The company's decision to exit precious metals refining in 2015 ended nearly two centuries of bar production. The refining operations, including some equipment and staff, were acquired by Asahi Refining (a subsidiary of Japan's Asahi Holdings). Bars produced before 2015 retain full LBMA recognition and are traded globally without restriction. The JM hallmark on a bar is effectively a historical stamp of quality from one of the founding names in modern bullion refining.

The 1g bar is a minted product sealed in a tamper-evident assay card. The card displays the JM logo, weight, purity, and a unique serial number. As with all LBMA-accredited bars, maintaining the sealed packaging is important for smooth resale, since an opened card may prompt a dealer to request independent assay verification.

Tax Position for JM 1g Gold Bars

Johnson Matthey 1g gold bars receive the same tax treatment as any 999.9 fine gold bar from an LBMA-accredited refinery. The discontinued production status has no effect on tax classification.

• United Kingdom: VAT-exempt as investment gold (995+ purity). Subject to Capital Gains Tax at 18-24% on disposal, with a £3,000 annual allowance. Not CGT-exempt (only UK legal tender coins qualify). SIPP-eligible for pension holders.
• United States: No federal sales tax; state sales tax varies by state. Capital gains taxed at up to 28% as a collectible. IRA-eligible (999.9 purity from an LBMA-accredited refiner meets IRS requirements). Must be held at an approved depository.
• Canada: GST/HST-exempt (gold bars at 99.5%+ purity).
• Australia: GST-free as investment-grade gold.
• European Union: VAT-exempt under the Investment Gold Directive.
• Singapore: GST-exempt under the IPM scheme.
• Hong Kong: No sales tax, no import duty, no capital gains tax.
• New Zealand: GST-exempt for fine gold bullion at 99.5%+ purity.

For UK buyers specifically, the lack of CGT exemption on bars is worth noting. A 1g gold bar, regardless of refiner, carries CGT liability on gains above the annual allowance. Buyers prioritising tax efficiency in the UK should consider CGT-exempt legal tender coins like the 1g Britannia gold bar, which is produced by The Royal Mint and benefits from UK legal tender status.

Johnson Matthey vs Active 1g Gold Bar Producers

The discontinued status of Johnson Matthey bars creates a natural comparison question: should a buyer choose a heritage JM bar or a currently-produced alternative? The answer depends on whether the buyer values historical provenance or current-production security features and consistent supply.

The 1g PAMP Fortuna bar is the market leader in branded 1g gold bars. PAMP's Lady Fortuna design is instantly recognisable, and bars produced since 2017 include Veriscan digital authentication. The PAMP brand commands a premium, but that premium buys wider resale recognition and an active manufacturer standing behind the product. For liquidity-focused buyers, the Fortuna is the safer bet.

The 1g Metalor bar offers a comparison from the Swiss refining sector. Metalor, founded in 1852 and now owned by Japan's Tanaka Kikinzoku, has a similar institutional pedigree to JM. Its bars feature BullionProtect security technology with smartphone-scannable authentication, a modern feature that JM's pre-2015 bars lack.

The 1g Royal Mint bar brings sovereign mint backing from the UK's official mint. For buyers in the United Kingdom, the Royal Mint name may offer stronger local recognition than Johnson Matthey at resale. The Royal Mint also continues to produce bars, meaning consistent supply and current packaging standards.

Where JM bars retain appeal is among collectors and buyers who value precious metals history. Johnson Matthey bars from certain production periods, particularly older large-format bars, command genuine collector premiums. At the 1g size, the collectible premium is modest, but the JM hallmark does carry a story that a generic or currently-produced bar does not. For pure investment purposes, a currently-produced LBMA bar from any major refiner is functionally identical and often more competitively priced.
