1/10 oz Perth Mint Koala Platinum Coin

The 1/10 oz Platinum Koala

The Platinum Koala was the world's first national platinum bullion coin series, struck by the Perth Mint from September 1988 until production ceased in 2000. The 1/10 oz size carries a $10 AUD face value and the same .9995 fineness as every other coin in the series. Because the programme ended a quarter of a century ago, every 1/10 oz Platinum Koala on the market today is a secondary market coin; there is no ongoing annual issue.

That discontinued status is the main reason to consider one. The series ran for just 12 years, the reverse design changed annually with koalas shown in different natural settings, and the final 2000 issue had a declared mintage of only 2,048 coins against a 100,000 maximum. Short production runs and low late-series mintages give the Platinum Koala a collectible dimension that current-production platinum coins lack, while the coin still trades primarily as bullion.

Buyers should go in with clear expectations about fractional platinum. Platinum coins already carry higher premiums than gold coins, and fractional sizes such as 1/4 oz and 1/10 oz can run to 15-25% or more over spot because production runs were small and demand is inconsistent. The 1/10 oz format suits buyers who want a low-cost entry into platinum or a piece of the first platinum bullion series, not those trying to accumulate platinum weight efficiently, where a 1 oz coin or bar does the job at a lower percentage premium. All Koalas carry the "P" mintmark and are government-guaranteed by the Government of Western Australia.

1/10 oz Platinum Koala Specifications

The series spanned eight sizes, from 1/20 oz up to 1 kg, with the larger 2 oz, 10 oz, and 1 kg pieces introduced in 1991. The 1/10 oz sits near the bottom of that range, and at 16.1mm it is a genuinely small coin that should be kept in its Perth Mint protective capsule both to avoid loss and to support resale.

Authentication is more straightforward than the coin's size suggests. Platinum's density of 21.45 g/cm3 is far above silver's 10.49 and meaningfully above tungsten's 19.25, so no common cheap metal convincingly mimics it; a precise weight check on a coin of known diameter is a strong test, and sigma or XRF testing is definitive. The series carries no additional anti-counterfeiting features beyond the strike itself, unlike the Perth Mint Kangaroo's later micro-engraving.

Platinum Koala Tax Treatment by Country

Platinum follows the silver pattern in most tax systems: it misses out on the special exemptions reserved for investment gold, so the purchase jurisdiction matters a great deal.

• United States: most states exempt bullion coins from sales tax; capital gains are taxed at the 28% collectibles rate. The Platinum Koala is specifically listed as IRA-eligible under IRS Section 408(m)(3)(A), a named inclusion rather than a generic purity qualification.
• United Kingdom: 20% VAT on purchase, and CGT applies on disposal because the Koala is Australian rather than UK legal tender. UK buyers wanting tax-advantaged platinum are limited to the Platinum Britannia, which is CGT-exempt though still VAT-liable.
• Australia: legal tender and GST-free as an investment-grade precious metal under the A New Tax System (GST) Act 1999; CGT applies on disposal, with a 50% discount for individuals after 12 months.
• Canada: 0% GST/HST for platinum at 99.5%+ purity, which the .9995 Koala exceeds.
• New Zealand: GST-exempt at 99%+ platinum purity; no formal CGT.
• Singapore: GST-exempt as a legal tender platinum coin at 99%+ purity; no CGT.
• Hong Kong: no sales tax, no import duty, no CGT.
• EU: standard VAT at national rates (17-27%); there is no investment platinum exemption equivalent to the investment gold rules.

The First National Platinum Bullion Series, 1988-2000

The Australian Government approved platinum minting on 18 June 1987, and the Perth Mint struck the first Platinum Koalas in September 1988. That made the Koala the first national coin series to offer 1 oz platinum bullion, beating the American Platinum Eagle to market by nearly a decade. The series launched with fractional sizes including the 1/10 oz, and added 2 oz, 10 oz, and 1 kg pieces in 1991.

The programme was commercially significant for Australia. The Perth Mint processed over 18 tonnes of platinum through the Koala series, with approximately 85% sold internationally, and Gold Corporation, the mint's parent, became one of Australia's top 30 export earners. The reverse design changed every year, depicting koalas in various natural settings, with the obverse carrying the effigy of Queen Elizabeth II.

Demand did not hold. Platinum investment interest in the late 1990s was thin, and production ceased in 2000 after just 12 years. The final year's declared mintage was 2,048 coins against a 100,000 maximum, a number that tells the story of why the series ended and also explains why late-date Koalas are now scarce. The Perth Mint eventually returned to platinum with the Platinum Kangaroo in 2018, but the Koala was never revived, leaving a complete, closed 12-year series with annual one-year designs.

Platinum Koala vs Platinum Eagle, Platinum Maple Leaf, and Noble

When it was in production, the Platinum Koala competed directly with three coins: the Canadian Platinum Maple Leaf (also launched 1988), the Isle of Man Noble, and from 1997 the American Platinum Eagle. The Koala was first of the national series to market with a 1 oz platinum coin, and all the majors settled on the same .9995 fineness.

Today the practical comparison is between a discontinued coin and current production. The American Platinum Eagle remains in annual production with 1 oz and fractional sizes including 1/10 oz, has the strongest resale demand in the US market, and is the easier coin to buy and sell. The Platinum Maple Leaf has had intermittent production but carries the Royal Canadian Mint's Bullion DNA security feature on modern issues. The Koala offers neither ongoing supply nor modern security features; its reeded edge and "P" mintmark are the extent of it.

What the Koala offers instead is scarcity and series interest. Annual design changes across a closed 12-year run, with the 2000 final year at just 2,048 coins, give it a collector angle the bullion-only buyer of an Eagle never gets. Liquidity cuts the other way: platinum coins already trade with wider spreads than gold, smaller dealers may not handle platinum at all, and a discontinued fractional issue narrows the buyer pool further. Buy the Koala for what it is, a piece of the first platinum bullion programme; buy the Eagle or Maple for straightforward platinum exposure.
