1 oz Australian Platypus Platinum Coin

Perth Mint's Next Generation Series in Platinum

The 1 oz Australian Platypus Platinum Coin is the 2021 release from Perth Mint's "Next Generation" series, which debuted in 2018. Each year features a different Australian native animal depicted alongside its young, and the 2021 instalment showcases a mother platypus swimming underwater with her newborn, searching for food along the bottom.

Struck in 999.5 fine platinum, this coin carries a $100 AUD face value and is legal tender in Australia under the Currency Act. The platinum version of the Platypus is more limited than its silver counterpart, positioning it for collectors and platinum investors who want an Australian sovereign mint product beyond the standard 1 oz Platinum Kangaroo.

The Next Generation series is distinctive among world bullion programmes. No other major mint has built an entire series around parental bonds in the animal kingdom. The Platypus design, created by Monique Reeves, renders a naturally elusive subject in detail, with micro-engraved radial lines across the field and rising bubbles adding texture to the underwater scene. Perth Mint's micro-laser engraved authentication letter, visible only under magnification, is present on the reverse.

The platypus itself is one of only five extant species of monotremes (egg-laying mammals), endemic to eastern Australia and Tasmania. Males carry a venomous spur on their hind legs. The animal's unusual biology and rarity make it one of the more distinctive subjects in bullion coin design, a step away from the eagles, kangaroos, and monarchs that dominate the category.

Platypus Platinum Coin Specifications

The platinum version shares the same reverse design as the silver piedfort (2 oz) and 10 oz releases from the same year, though scaled to standard 1 oz platinum coin dimensions. The silver version was struck in piedfort style at 40.90 mm diameter and 6.02 mm thickness to accommodate 2 oz of silver within a 1 oz coin diameter, giving it a distinctive chunky profile. The platinum version uses the conventional dimensions for a 1 oz platinum coin.

Next Generation Series Chronology

Perth Mint applies micro-laser engraved lettering and radial line anti-counterfeiting features across the Next Generation series. The mint's "P" mintmark appears on the reverse of all issues. The series has run continuously since 2018 with a new animal each year, each depicting a mother and baby pair, a thematic thread unique among world bullion coin programmes. The 2024 emu release is notable in that emus are one of the few species where the father raises the young rather than the mother.

Tax Position of the Australian Platypus Platinum Coin

As an Australian legal tender platinum coin at 999.5 fineness, the Platypus meets investment-grade thresholds in most jurisdictions. Tax treatment follows platinum's general pattern: less favourable than gold in most countries, but with some relief available.

Australia

Investment-grade platinum at 99% purity or above is GST-free. Perth Mint coins are among the most trusted domestic products and are available directly through the mint's retail channels. Capital gains tax applies on disposal, with a 50% discount for holdings exceeding 12 months.

United Kingdom

Platinum coins attract 20% VAT on purchase. Perth Mint coins are not UK legal tender, so they are not CGT-exempt on disposal. Both taxes apply, making physical platinum expensive for UK investors. Vault storage outside the UK can defer VAT, but delivery to the UK triggers the charge.

United States

The 999.5 purity meets the IRS threshold for precious metals IRA eligibility (99.95% for platinum). Most states exempt investment-grade bullion from sales tax. Capital gains are taxed at the 28% collectibles rate.

Canada

Platinum at 99.5% or above is GST/HST-exempt. Capital gains are subject to the 50% inclusion rate.

New Zealand

Platinum at 99% purity or above is GST-exempt. No capital gains tax applies. Perth Mint is the nearest major sovereign mint for NZ buyers, making Australian bullion a natural choice.

Singapore

Platinum coins at 99% purity or above that qualify as Investment Precious Metals are GST-exempt (9% GST rate otherwise). No capital gains tax.

Hong Kong

No sales tax, import duty, or capital gains tax on platinum.

Australian Platypus vs Other 1 oz Platinum Coins

The Platypus competes with both Perth Mint's own 1 oz Platinum Kangaroo and the broader field of sovereign mint platinum coins.

Against the Kangaroo, the Platypus is a limited-run product from a themed series, while the Kangaroo is Perth Mint's ongoing annual platinum bullion line with changing designs and larger production volumes. The Kangaroo will generally be easier to source and may carry slightly lower premiums. The Platypus appeals to buyers who collect the Next Generation series across years or who prefer the more distinctive wildlife subject.

The 1 oz Platinum Britannia from The Royal Mint offers a significant tax advantage for UK buyers: CGT exemption on disposal as UK legal tender. No Perth Mint coin matches this benefit in the UK market. The Britannia also has broader UK dealer availability.

The 1 oz American Platinum Eagle dominates the US market with the deepest dealer network and strongest IRA infrastructure. The Platypus is available from US dealers but is a niche alternative.

The 1 oz Platinum Maple Leaf from the Royal Canadian Mint matches the Platypus on purity but adds Bullion DNA digital authentication, a security feature Perth Mint's Next Generation coins lack. Production of the Platinum Maple Leaf has been intermittent, so availability fluctuates.

Perth Mint coins carry micro-laser engraved authentication letters, a simpler but effective anti-counterfeiting measure. Platinum's high density (21.45 g/cm3) already makes counterfeiting difficult, as few cheaper metals come close to this weight. The Platypus's strongest differentiator is its subject matter and the thematic continuity of the Next Generation programme, which gives each year's release a coherent narrative that standard bullion coins lack.
