Australian Platypus Platinum

Perth Mint's Platypus in Platinum

The Australian Platypus platinum coin is the 2021 release from Perth Mint's Next Generation series, a programme that pairs each year's issue with a different native Australian mother-and-baby animal. The platinum version contains one troy ounce of 999.5 fine platinum, struck as Australian legal tender with a $100 AUD face value. It carries the same Monique Reeves reverse design found on the silver and gold versions: a mother platypus swimming underwater with her young, searching for food along the bottom, with bubbles rising around the pair.

For platinum investors, the coin's main appeal lies in its combination of sovereign government backing, Perth Mint's strong brand reputation, and the relatively limited production volumes of the Next Generation programme. Perth Mint is government-owned by the State of Western Australia and has been operating since 1899, giving its products a level of institutional trust that few private mints can match. The 999.5 purity meets the standard for all major platinum bullion coins globally, matching the 1 oz American Platinum Eagle, 1 oz Platinum Maple Leaf, and 1 oz Platinum Britannia.

Platinum bullion represents a much smaller market than gold or silver, with total investment demand accounting for roughly 8.5% of overall platinum usage in 2024. That concentration means the range of available platinum coins is narrower, and a Perth Mint issue with proven collector crossover appeal can stand out. The Next Generation's annual animal rotation adds a collectible dimension that fixed-design platinum coins lack, giving the Platypus issue an identity beyond its metal content.

Platypus Platinum Coin Specifications

Security and Authentication

The Platypus platinum coin incorporates Perth Mint's standard authentication features for the Next Generation series. Micro-laser engraved text inscriptions on the reverse contain a letter visible only under magnification, providing a layer of anti-counterfeiting protection that is difficult to replicate. Both the obverse and reverse fields include micro-engraved radial lines for enhanced aesthetics and additional security. The Perth Mint "P" mintmark appears on the reverse. Platinum's high density (21.45 g/cm3, denser than gold) makes weight-based counterfeiting particularly difficult, since few affordable metals approach that density.

Platinum Platypus Tax Treatment by Country

Platinum bullion faces a different tax landscape from gold in most jurisdictions. The key distinction is that many countries exempt investment gold from sales tax but apply full rates to platinum, making the purchase tax a significant cost factor.

• Australia: Perth Mint platinum coins at 999.5 purity are GST-free as investment-grade precious metals under Australian tax law. The GST exemption threshold for platinum in Australia is 99%, so the Platypus comfortably qualifies. This makes Australia one of the most favourable countries for purchasing platinum bullion.
• United Kingdom: Platinum is subject to 20% VAT on purchase, regardless of purity or legal tender status. This is the same rate applied to silver. The Platypus is not UK legal tender, so any profits on disposal are also subject to Capital Gains Tax (CGT). UK buyers seeking CGT exemption on platinum should consider the 1 oz Platinum Britannia, which is CGT-exempt as UK legal tender. Some UK dealers offer VAT-free vault storage for platinum, where the metal is held in a bonded facility and no VAT is charged unless physical delivery is requested.
• United States: No federal sales tax applies. State-level treatment varies, but 35 or more states exempt investment-grade precious metals from sales tax. The 999.5 purity meets IRS requirements for precious metals IRAs (which require platinum at 99.95% fineness). Gains on disposal are taxed at the collectibles rate, up to 28% for long-term holdings.
• Canada: Platinum at 99.5% purity or higher is GST/HST-exempt in bar, ingot, coin, or wafer form. The Platypus qualifies, making Canadian purchases straightforward.
• New Zealand: Platinum at 99% purity or higher is GST-exempt. New Zealand has no capital gains tax, making it one of the most tax-efficient jurisdictions for platinum.
• Singapore: Qualifies as an Investment Precious Metal (IPM) under Singapore's GST exemption scheme, provided the refiner holds LPPM accreditation (Perth Mint does). No capital gains tax applies.
• South Africa: Platinum bullion is subject to 15% VAT. Unlike the gold Krugerrand, there is no platinum coin exemption in South Africa.
• Hong Kong: No sales tax, no import duty, and no capital gains tax on platinum. Fully tax-free.

Platypus vs Other 1 oz Platinum Coins

The platinum coin market is considerably smaller than gold or silver, with five major sovereign mint options dominating the 1 oz category. The Platypus sits outside this core group as a themed annual issue, which shapes its competitive position.

The 1 oz Platinum Maple Leaf from the Royal Canadian Mint is often the most competitively priced sovereign platinum coin, with strong global dealer availability and the same 999.5 purity. The Maple Leaf's fixed design (unchanged since 1988) provides maximum recognition in the secondary market but no collector variation. The 1 oz American Platinum Eagle carries the strongest brand recognition in North America and is IRA-eligible. It also comes in fractional sizes (1/2, 1/4, and 1/10 oz), though fractional platinum premiums are steep (15-30% over spot).

For UK buyers specifically, the 1 oz Platinum Britannia is the only platinum coin that offers CGT exemption, a meaningful advantage given the 20% VAT already charged on purchase. The 1 oz Platinum Philharmonic from the Austrian Mint, introduced in 2016, uses the same orchestral design as its gold and silver counterparts and has strong dealer penetration in European markets.

Against this field, the Platypus offers three differentiators. First, its design changes annually as part of the Next Generation rotation, giving each year's issue a distinct identity. The series has featured a different Australian animal mother-and-baby pair each year since 2018 (Koala, Crocodile, Kookaburra, Platypus, Dingo, Kangaroo, Emu). Second, Perth Mint's brand commands strong respect in both the Australian and international markets. Third, the annual mintage is more constrained than for coins like the Eagle or Maple Leaf, which have no practical cap on production volumes.

The trade-off is secondary market liquidity. A Platinum Eagle or Maple Leaf will find a buyer at virtually any dealer worldwide. The Platypus, as a themed issue, may take slightly longer to sell and could command a narrower buyback price at dealers who do not regularly stock it. For investors who prioritise maximum resale ease, the core sovereign coins remain the default. For those who value the combination of a sovereign government guarantee, annual design variety, and Perth Mint provenance, the Platypus fills a niche that the fixed-design majors do not.
