5g Classic Platinum Bar

A Pocket-Sized Platinum Bar from an LBMA Referee

The 5g Argor-Heraeus Classic platinum bar is a minted ingot of 999.5 fine platinum from one of the most credentialled refiners in the business. Argor-Heraeus holds LPPM Good Delivery status for platinum and palladium alongside LBMA Good Delivery for gold (since 1961) and silver (since 1992), and it is one of only seven global LBMA Referees, the panel that audits other refiners' Good Delivery compliance. Every Classic bar carries an individual serial number, is certified by an Argor-Heraeus sworn assayer, and ships in a numbered tamper-evident assay card.

The honest framing for a 5g platinum bar is that it is an entry point, not an efficient accumulation vehicle. Small gram-weight platinum bars carry very high premiums, roughly 20-40% over spot for the 1g-5g sizes against 5-10% for 1 oz minted bars, because fixed fabrication costs dominate at tiny weights and platinum's 1,768C melting point makes it harder to work than gold. Buyers wanting cost-efficient platinum exposure should look at 1 oz platinum bars or larger; the 5g format suits gifts, first purchases, and small incremental savings.

What the Classic line offers at this size is maximum verifiability for minimum outlay. The deliberately minimal design, refiner logo, weight, metal, purity, and serial number with a blank or logo-patterned reverse, exists to keep production costs down and authentication marks legible. Platinum itself helps too: it does not tarnish or corrode, so the sealed card needs no atmospheric precautions.

5g Classic Platinum Bar Specifications

The obverse carries the Argor-Heraeus logo, a stylised AH monogram within a double circle with Argor-Heraeus SA around the ring and Switzerland below, followed by the weight, metal type, and purity in vertical arrangement, plus the individual serial number and sworn assayer mark. A year-of-manufacture stamp has appeared on all Argor-Heraeus bars since 1988. The 5g sits within a platinum Classic range that runs from 1g through 10g, 20g, 50g, 100g, 500g, and 1 kg, all minted; the wider Classic line also covers gold at 999.9, silver, and palladium at 999.5.

Authentication is unusually easy for platinum. Its density of 21.45 g/cm3 has no cheap convincing substitute: tungsten at 19.25 g/cm3 would be detectably light in a bar of correct dimensions, and the only denser candidates, iridium and osmium, cost more than platinum itself. Counterfeit platinum bars are accordingly rare. The sealed, serial-numbered assay card provides chain-of-custody assurance and should be kept intact, since sealed bars from recognised refiners command better resale prices than loose ones.

Tax Treatment of a 999.5 Platinum Bar

Platinum bars are not legal tender and get no CGT exemption anywhere, and platinum misses the investment-gold VAT carve-outs in Europe.

• United Kingdom: 20% VAT applies on purchase, and gains are CGT-liable on sale, making platinum bars the least tax-efficient platinum form for UK buyers. VAT can be deferred under specific bonded storage arrangements, such as Zurich or Delaware free zone vaulting, but that means the bar is stored rather than delivered.
• EU: standard national VAT rates of 17-27% apply; there is no investment exemption for platinum.
• United States: most states exempt bullion from sales tax, though a roughly $500 purchase can fall below the exemption thresholds some states apply. The bar is IRA-eligible: the IRS requires 99.95%+ for platinum, and 999.5 meets that threshold exactly. Long-term gains outside an IRA are taxed at the collectibles rate of up to 28%.
• Canada: platinum at 99.5%+ purity in bar form is GST/HST exempt.
• Australia: investment-grade platinum is GST-free at 99%+ purity, which this bar meets.
• New Zealand: platinum at 99%+ purity is GST-exempt, with no formal capital gains tax.
• Singapore: platinum at 99%+ purity from a qualifying refiner is GST-exempt under the IPM scheme, with no capital gains tax.
• Hong Kong: no sales tax, duty, or capital gains tax.
• Switzerland: platinum carries 8.1% VAT; only investment gold is exempt.

From Chiasso Garage of 1951 to Heraeus Subsidiary

Argor SA was founded in 1951 in Chiasso, in the Swiss canton of Ticino, and earned LBMA Good Delivery accreditation for gold a decade later in 1961. Union Bank of Switzerland took full ownership in 1973, and COMEX accreditation followed in 1974. The defining corporate moment came in 1986, when a joint venture with Heraeus Holding GmbH of Hanau, Germany created the Argor-Heraeus name; the refinery relocated to a purpose-built facility in Mendrisio, Ticino in 1988. UBS exited in 1999, and after years of shared ownership involving Heraeus, Commerzbank, the Austrian Mint, and company management, Heraeus completed full acquisition on 13 July 2017, making Argor-Heraeus SA a wholly owned subsidiary.

The Classic line is the company's foundational product, the core minted and cast ingots dating from the founding era, and the name now distinguishes these standard bars from the later specialty lines: the Kinebar with its kinegram holographic security (launched 1994), the Lunar Calendar, Origin Traced, and Small Craft ranges. The serial-numbering scheme for the company's 400 oz Good Delivery cast gold bars has run continuously and unchanged since 1952, a small but telling marker of institutional continuity.

Today the Mendrisio refinery has an annual gold refining capacity of roughly 400 tonnes, placing it in the same tier as PAMP and Valcambi within the Ticino refining cluster, and the firm has held a seat among the LBMA's Referees since the panel was constituted in 2003. The same house that strikes this 5g platinum bar audits other refiners' bars for compliance.

5g Classic Platinum vs PAMP, Valcambi, and Bigger Bars

At this weight the direct rivals are the other Swiss LBMA-accredited refiners. PAMP Suisse produces platinum bars from 1g to 100g sealed in assay cards, and Valcambi offers multiple sizes including its divisible CombiBars; Heraeus serves the same market from Germany. All are accredited refiners with sealed-card packaging, so the products are close to interchangeable in quality and resale treatment. The Argor-Heraeus differentiators are institutional rather than visual: LBMA Referee status and the sworn-assayer certification on every serialised bar. Where the Classic deliberately omits decoration, PAMP's signature bars carry the Fortuna artwork, a matter of taste with little premium consequence at 5g.

The more consequential comparison is vertical. Platinum bar premiums fall steeply with size, from roughly 20-40% over spot at 1g-5g to 10-20% at 10g, 5-10% at 1 oz, and 4-8% at 100g. The 1 oz bar is both the most commonly traded retail size and the best-liquidity platinum bar, which is why dealers treat it as the minimum practical investment size; a buyer accumulating platinum seriously gets several times more metal per premium dollar there. The 5g Classic gold bar from the same line faces gentler small-size penalties, since gold's larger market and easier fabrication keep gram-bar premiums lower. The 5g platinum Classic wins on one axis only: the smallest credible entry ticket to a credentialled refiner's platinum, in a format that stores flat, stacks easily, and authenticates itself by density.
