1/10 oz Perth Mint Koala Gold Coin

The 1/10 oz Perth Mint Koala Gold Coin

This coin contains one tenth of a troy ounce (3.11 g) of 999.9 fine gold and is struck by the Perth Mint, whose output is guaranteed by the Government of Western Australia. The tenth-ounce format is the smallest commonly produced fractional gold coin size, and it serves a specific purpose: it is the lowest-cost route into gold coin ownership from a major sovereign mint, useful for gifting, for spreading a purchase across many small units, and for buyers who want maximum divisibility when the time comes to sell.

That flexibility has a price. Manufacturing costs for die work, quality control, and packaging are nearly the same for a tenth-ounce coin as for a full ounce, but they are spread over one tenth of the gold. As a result, 1/10 oz gold coins carry the highest relative premiums of any standard bullion weight. Accumulating one ounce of gold through ten tenth-ounce coins costs materially more than buying a single one-ounce coin, so this size suits buyers who value the small unit itself rather than those building bulk ounces.

The 999.9 purity is a practical advantage over the 22-carat alternatives at this weight. In jurisdictions that set tax exemptions by fineness, a four-nines coin clears the thresholds that alloyed coins such as the tenth-ounce Krugerrand or American Gold Eagle miss. Coins this small (roughly 16.5 mm diameter for comparable tenth-ounce issues) are easy to misplace, so capsules or mint tubes are essential for storage.

Tax Treatment of the 1/10 oz Gold Koala by Country

At 999.9 fine, this coin sits comfortably above the purity thresholds most jurisdictions use to define investment gold.

• UK: Investment gold of 995+ fineness is VAT-free, so the coin attracts no VAT. It is not UK legal tender, however, so it carries no Capital Gains Tax exemption; gains above the annual allowance (currently £3,000) are taxable, unlike a 1/10 oz gold Britannia.
• USA: No federal sales tax; most states exempt bullion, though a handful still tax it. Note that several states only exempt purchases above a value threshold (California $2,000, New York $1,000, Florida $500), which a single tenth-ounce coin may not reach. Long-term gains are taxed at the collectibles rate of up to 28%, and the 999.9 fineness meets the IRS 99.5% purity requirement for gold IRAs.
• Canada: Gold refined to 99.5%+ in coin form is GST/HST exempt, so no sales tax applies. Capital gains are taxable at the 50% inclusion rate, though the Listed Personal Property rule means a coin both bought and sold for under $1,000 CAD generates no reportable gain.
• Australia: The home market. Investment-grade gold at 99.5%+ purity is GST-free. CGT applies on disposal, with a 50% discount for individuals holding over 12 months.
• New Zealand: GST-exempt at 99.5%+ purity, a genuine edge over 22-carat tenth-ounce coins (Eagle, Krugerrand), which fall below the threshold and attract 15% GST.
• Singapore and Hong Kong: No GST on qualifying investment gold in Singapore and no sales tax in Hong Kong; neither charges capital gains tax.

Gold Koala vs Eagle, Britannia, and Maple Leaf at 1/10 oz

Every major mint produces a tenth-ounce gold coin, so the Koala competes in a crowded field. The 1/10 oz American Gold Eagle is the most popular fractional gold coin in the world and the most liquid choice in the US market. It is 22-carat (.9167) with a $5 face value and ships in sealed US Mint tubes of 50. Its alloyed composition costs it tax efficiency outside the US: in New Zealand it attracts 15% GST where the four-nines Koala does not, and it relies on a specific statutory exemption for US IRA eligibility rather than meeting the purity rule outright.

The 1/10 oz gold Britannia is the decisive pick for UK buyers. As UK legal tender it is exempt from Capital Gains Tax as well as VAT, and at roughly £300 to £350 it is the cheapest entry into CGT-free gold. The Koala cannot match that in the UK. Both coins are 999.9 fine and around 16.5 mm in diameter; Britannias come in tubes of 25.

The 1/10 oz Canadian Maple Leaf matches the Koala's .9999 purity and benefits from the Royal Canadian Mint's wide recognition. Liquidity is the practical differentiator across all of these: dealers buy back tenth-ounce sovereign coins readily, but bid-ask spreads at this weight are the widest of any fractional size, and the best resale pricing goes to the Eagle and Britannia. The Koala's case rests on Perth Mint quality and four-nines purity at the smallest mainstream price point, rather than on beating those two for liquidity.
