1/4 oz Perth Mint Koala Platinum Coin

The 1/4 oz Platinum Koala from Perth Mint

The 1/4 oz Platinum Koala contains 7.7759 grams of 999.5 fine platinum, carrying a face value of A$25 as Australian legal tender. This denomination was part of the Perth Mint's original Platinum Koala range, which launched in 1988 and ran until 2000. The programme holds the distinction of being the first sovereign platinum bullion coin series, arriving nearly a decade before the American Platinum Eagle.

The 1/4 oz sits at the midpoint of the fractional range, offering more platinum than the 1/10 oz and 1/20 oz sizes while costing roughly half as much as the 1/2 oz Platinum Koala. This makes it a practical size for buyers who wanted platinum exposure during the original production period without committing to a full ounce.

Every year from 1988 to 2000, the Perth Mint struck a new reverse design depicting koalas in natural Australian bush settings. This twelve-year run produced a limited number of design variations, and with the programme discontinued, the total population of 1/4 oz Platinum Koalas is fixed. Early-year coins and the scarce final-year 2000 vintage are particularly sought after on the secondary market. All coins carry the "P" mintmark and the Government of Western Australia's guarantee of weight and purity.

1/4 oz Platinum Koala Specifications

The 1/4 oz Koala is almost identical in diameter to the 1/4 oz Platinum Maple Leaf (20.1 mm vs 20.0 mm) but slightly thicker (1.90 mm vs 1.78 mm). Perth Mint coins were supplied in individual protective capsules. The coin is compact enough for easy storage but large enough that the koala design details are visible to the naked eye, unlike the tiny 1/20 oz denomination.

Tax Treatment of the 1/4 oz Platinum Koala

Tax treatment for the Koala is identical across all denominations. The 1/4 oz follows the same rules as the 1 oz and other fractional sizes.

• Australia: GST-free as investment-grade platinum (99%+ purity). CGT on disposal with a 50% discount for holdings over 12 months. Legal tender at face value.
• United States: IRA-eligible (Platinum Koala specifically listed under IRS Section 408(m)(3)(A)). Collectibles CGT rate of up to 28%. Most states exempt bullion from sales tax.
• United Kingdom: 20% VAT on purchase. CGT on disposal. Not CGT-exempt (not UK legal tender).
• Canada: GST/HST exempt at 99.5%+ purity. Capital gains at 50% inclusion rate.
• New Zealand: GST-exempt at 99%+ purity. No CGT.
• Singapore: GST-exempt as IPM. No CGT.
• Hong Kong: No sales tax, no duties, no CGT.

1/4 oz Platinum Koala vs Other Quarter-Ounce Platinum Coins

The 1/4 oz Platinum Maple Leaf is the closest rival. Both contain 7.78 grams of 999.5 fine platinum and date from the same 1988 launch year. The Koala's advantage is its annual design change and closed-series collectibility. The Maple Leaf's advantages are its fixed recognisable design, the Bullion DNA authentication system (post-2014 coins), and better ongoing availability (the RCM periodically produces fractional platinum, while the Koala is entirely secondary market).

The American Platinum Eagle 1/4 oz is the most liquid product at this weight in North American markets. It carries a US$25 face value and the strongest brand recognition among US dealers and IRA custodians. Premiums on the Eagle tend to be slightly higher than on the Maple Leaf or Koala.

Within the Perth Mint's own platinum range, the Koala can be compared to the 1/4 oz Platinum Kookaburra if available. Both share Perth Mint production quality, 999.5 fineness, and annual design changes. The Koala has a longer platinum history (1988-2000) and the first-mover significance of being the first national mint platinum coin.

For buyers choosing between Koala denominations, the step from 1/4 oz up to 1/2 oz offers a meaningful reduction in premium per ounce. The step down to 1/10 oz pushes premiums sharply higher. The 1/4 oz is the practical sweet spot for buyers who find the 1/2 oz too expensive but want to avoid the steep per-ounce costs of the smallest fractionals.
