10 oz Kookaburra Silver Coin

The 10 oz Silver Kookaburra

The 10 oz Kookaburra is a large-format silver coin from the Perth Mint, struck in .999 fine silver (upgraded to .9999 from 2018 onward). It combines the Kookaburra series' defining feature, a new reverse design each year featuring Australia's laughing kingfisher, with the premium savings that come from a larger denomination. At 10 troy ounces, it sits in the middle ground between the popular 1 oz Kookaburra and the 1 Kilo Kookaburra, offering lower per-ounce premiums than the 1 oz while remaining more divisible than the kilo.

The Kookaburra programme has been running since 1990, making it one of the longest-running annual-design silver coin series. The 10 oz denomination carries a face value of A$10 and has been a consistent part of the range alongside the 1 oz and 1 kg sizes. Each year's reverse depicts one or more kookaburras in a natural Australian setting, and the annual design changes give earlier vintages genuine collector value, particularly low-mintage years from the 1990s and 2000s.

For buyers looking at 10 oz silver coins specifically, the Kookaburra competes with the 10 oz Queen's Beasts, the 10 oz Tudor Beasts, and the 10 oz Perth Lunar. The Kookaburra's advantage is the combination of Perth Mint provenance, government-backed purity, and the longest track record of annual design changes in this weight class.

10 oz Kookaburra Dimensions and Details

The obverse has carried four different monarch portraits since the series began: Raphael Maklouf's Elizabeth II (1990-1998), Ian Rank-Broadley's Elizabeth II (1999-2018), Jody Clark's Elizabeth II (2019-2023), and King Charles III (2024 onward). The reverse design changes annually, always featuring the kookaburra, and is the primary identifier of each year's issue.

The purity upgrade from .999 to .9999 in 2018 aligned the Kookaburra with the Canadian Maple Leaf's standard and gave it a technical edge over .999 coins like the American Silver Eagle and Austrian Philharmonic. For practical purposes, the difference between three-nines and four-nines fine silver is negligible in terms of metal value, but it matters for tax qualification in some jurisdictions where the threshold is exactly 99.9%.

Tax Treatment of the 10 oz Silver Kookaburra

The Kookaburra is Australian legal tender at its stated face value. Tax treatment varies by the buyer's jurisdiction, and silver is treated less favourably than gold in most countries.

• Australia: GST-free as investment-grade precious metal. The .999/.9999 purity exceeds Australia's 99.9% threshold. Subject to capital gains tax on disposal, with a 50% CGT discount available for individuals holding longer than 12 months.
• United States: The .999/.9999 purity meets the IRS threshold for IRA eligibility under the generic bullion provision (silver must be 99.9%+ fine). Some custodians specifically list Perth Mint products. Capital gains are taxed at the 28% collectibles rate for long-term holdings. Sales tax varies by state.
• United Kingdom: Subject to 20% VAT on purchase. Not CGT-exempt because the Kookaburra is not UK legal tender. For UK buyers, the 10 oz Tudor Beasts and 10 oz Queen's Beasts offer the same 10 oz format with UK CGT exemption.
• Canada: GST/HST exempt at .999+ purity for qualifying bullion coins.
• EU: Subject to local VAT rates on silver (19% Germany, 21% Netherlands, etc.). Margin scheme taxation may apply on secondary market purchases in some countries, reducing the effective VAT to the dealer's margin only.
• Singapore: GST-exempt as Investment Precious Metal (IPM) provided the coin meets the 99.9% purity threshold and is legal tender.
• Hong Kong: No sales tax, no import duty, no capital gains tax.
• New Zealand: GST-exempt for silver at 99.9%+ purity.

Kookaburra vs Other 10 oz Silver Coins

The 10 oz silver coin market is smaller than the 1 oz market, with fewer competing products. The main alternatives to the Kookaburra at this weight are all from sovereign mints with strong reputations.

The 10 oz Queen's Beasts from The Royal Mint is struck in .9999 fine silver and carries UK CGT exemption as legal tender. The series ran from 2016 to 2021 and is now complete, meaning supply is fixed to secondary market availability. For UK buyers, the CGT exemption is a decisive advantage over the Kookaburra. The Queen's Beasts carried a GBP 10 face value and featured ten heraldic beasts from Elizabeth II's coronation.

The 10 oz Tudor Beasts, also from The Royal Mint, is the successor series (2022-2026) with the same .9999 purity and UK CGT exemption. It carries a GBP 10 face value and features beasts from the Hampton Court Palace Moat Bridge. For UK buyers seeking a 10 oz silver coin that is still in production, the Tudor Beasts is the natural choice. Both Royal Mint series include guilloche security patterning.

The 10 oz Perth Lunar is from the same mint as the Kookaburra and follows the Chinese zodiac calendar through 12-year cycles (currently Series III, 2020-2031). The Lunar's zodiac theme gives it strong appeal in Asian markets, and Dragon year coins are consistently the fastest to sell out. Purity matches the Kookaburra at .9999 for current issues. Both carry A$10 face value at this size.

Compared to 10 oz silver bars, all four coins carry higher premiums. Bars at 10 oz typically sit at 3-6% above spot, while coins add the cost of legal tender status, more complex minting, and in some cases collectible design premiums. The premium difference is the price of liquidity, government backing, and the potential for collector appreciation on specific vintages.
