100g Perth Mint Platinum Bar

Government-Backed Australian Platinum at 100g

The 100g Perth Mint Platinum Bar is produced by Australia's oldest operating mint, which is wholly owned by the Government of Western Australia. This sovereign backing distinguishes Perth Mint products from privately-owned refiners: the guarantee of weight and purity carries the full faith of a state government, not just a corporate reputation. For buyers who prioritise institutional trust above brand aesthetics, this government guarantee is a meaningful differentiator.

The Perth Mint has been refining precious metals since 1899 and holds both LBMA and LPPM (London Platinum and Palladium Market) accreditation. The mint produces platinum in a limited range of bar sizes compared to its extensive gold and silver programmes, reflecting platinum's smaller retail investment market. The 100g bar sits at the upper end of the retail range, offering compressed premiums relative to the mint's 1 oz and 10 oz products.

In the Australian domestic market, Perth Mint bars benefit from the strongest possible local provenance. They are the default platinum bar for Australian dealers and self-managed super fund (SMSF) investments. In Asia-Pacific markets more broadly (Singapore, Hong Kong, Japan), Perth Mint carries strong brand recognition and reliable dealer buyback support.

100g Perth Mint Platinum Bar Specifications

The bar carries Perth Mint's distinctive branding alongside weight, fineness, and serial number markings. It is sealed in tamper-evident assay card packaging with an integrated certificate. Perth Mint bars feature the mint's swan logo and, depending on production year, a kangaroo design element that connects the product to Perth Mint's broader bullion range.

Perth Mint's dual LBMA and LPPM accreditation covers both the gold/silver (LBMA) and platinum/palladium (LPPM) markets specifically. This dual listing confirms the mint's platinum refining capabilities are independently verified to the highest market standards.

Tax Treatment for the 100g Perth Mint Platinum Bar

Australia

The 100g Perth Mint Platinum Bar is GST-free for Australian buyers. The Australian GST exemption for precious metals applies to platinum at 99% purity or above in investment form (bars, coins, wafers) from recognised refiners. The 999.5 fineness exceeds this threshold. Capital Gains Tax applies on disposal, with a 50% CGT discount available for holdings over 12 months. The bar qualifies for Self-Managed Super Fund (SMSF) inclusion, which shelters gains from CGT within the superannuation wrapper.

United Kingdom

20% VAT on purchase. Subject to Capital Gains Tax on disposal at 18-24%. No CGT exemption (not legal tender).

United States

IRA-eligible at 99.95% purity from an accredited refiner. Most states exempt investment platinum from sales tax.

Canada

GST/HST exempt at 99.5%+ purity in bar form.

New Zealand

GST-exempt (platinum threshold is 99% purity). No capital gains tax in New Zealand. Perth Mint products are well-known to NZ dealers due to the geographic proximity and trans-Tasman trade in bullion.

Singapore

GST-exempt under the IPM scheme. Perth Mint's LPPM accreditation specifically satisfies Singapore's requirement for platinum bars to come from an LPPM-accredited refiner.

Hong Kong

No tax of any kind on platinum bullion.

Perth Mint 100g vs Other Platinum Bars at This Weight

The Perth Mint's primary competitive advantage is its government guarantee, which no private refiner can match. The question is whether this guarantee justifies any premium difference over LBMA-accredited private refiners.

The 100g Heraeus Platinum Bar typically trades at similar or slightly lower premiums. Heraeus has deeper liquidity in European markets where Perth Mint is less commonly stocked. For European buyers, Heraeus offers lower transaction costs and more competitive dealer buyback rates domestically.

The 100g PAMP Suisse Platinum Bar commands a higher premium due to brand positioning and VeriScan authentication. In Singapore's bullion market, both PAMP and Perth Mint are Tier 1 brands with strong dealer support. PAMP wins on authentication technology; Perth Mint wins on government backing.

For Australian buyers specifically, the Perth Mint bar is the path of least resistance. Domestic dealers stock it, SMSF custodians accept it without question, and resale to Australian dealers involves no import complications or brand recognition issues. The 100g Baird and Co. Platinum Bar occupies a similar default-domestic-choice position for UK buyers.
