1/10 oz Sovereign Gold Coin

The Newest Denomination in Britain's Oldest Gold Coin

The 1/10 oz Sovereign is a recent addition to the Sovereign range, extending a lineage that dates back to Henry VII's original gold sovereign of 1489. It contains 3.11 grams of 22 carat (916.7 fine) crown gold, the same alloy composition that has defined the Sovereign for over 500 years: 91.67% gold alloyed with 8.33% copper.

Like all Sovereign denominations, the 1/10 oz carries UK legal tender status with a face value of 25 pence, making it exempt from both VAT and Capital Gains Tax. This places it in the same privileged tax category as the full Sovereign, the half Sovereign, and the 1/10 oz Britannia.

The Sovereign's 22 carat composition is both its distinguishing feature and its limitation in the context of fractional gold. The copper alloy makes the coin harder and more scratch-resistant than 24 karat alternatives, and gives it the warm, slightly rosy tone that Sovereign collectors value. But at 91.67% purity, the 1/10 oz Sovereign does not meet the IRS threshold for US IRA inclusion (99.5% for gold), and in Australia it falls below the 99.5% purity threshold for GST-exempt investment gold.

The reverse carries the iconic St George and the Dragon design by Benedetto Pistrucci, originally engraved in 1817 and considered one of the masterworks of numismatic art. From 2026, the Royal Mint introduced advanced security features to the Sovereign range for the first time, including Garter motto text and an optical security image on the obverse.

1/10 oz Sovereign Technical Specifications

Sovereign Denomination Family

The 22 carat crown gold standard was established by Henry VIII in 1526 and has been maintained for the Sovereign for over 500 years. Every denomination uses exactly the same alloy composition, with total weight and gold content scaling proportionally. The copper alloy gives all Sovereigns a warmer colour than 24 karat coins and greater resistance to surface marks, a practical advantage for coins that may be handled frequently.

The obverse features King Charles III by Martin Jennings (from 2023). The reverse carries Benedetto Pistrucci's St George and the Dragon, originally engraved in 1817 and in near-continuous use for over two centuries. The design's extreme detail, including horse musculature, cape folds, and dragon scales, provides inherent anti-counterfeiting protection. From 2026, the Royal Mint added explicit security features to the Sovereign for the first time: Garter motto text and an optical security image on the obverse, alongside a return to the traditional yellow crown gold colour.

The 2017 200th anniversary Sovereign restored the original Garter ribbon design that Pistrucci intended, limited to 1,817 pieces. The 2025 issue introduced a 999 fine silver Sovereign for the first time, breaking the 500-year tradition of gold-only production.

1/10 oz Sovereign Tax Treatment

The Sovereign's tax status is identical across all denominations. The 1/10 oz benefits from the same exemptions as a full Sovereign or a Double Sovereign.

United Kingdom

• VAT: 0%. Exempt as UK legal tender and investment gold.
• CGT: Exempt. Under TCGA 1992, Section 21(1)(b), sterling legal tender coins are not chargeable assets. This applies to all Sovereign denominations, both modern and historic.
• Income Tax note: If you trade Sovereigns as a business (habitual buying and selling for profit), HMRC may classify gains as income rather than capital gains. The CGT exemption applies to individual investors, not dealers.
• SIPP: Gold Sovereigns are eligible for Self-Invested Personal Pensions.

United States

• IRA: Not eligible. The 91.67% gold purity is below the IRS Section 408(m) threshold of 99.5% for gold, and Sovereigns do not have the special Congressional exemption granted to American Eagles.
• Capital gains: Taxed as collectibles at a maximum 28% federal rate.

Canada

• GST/HST: The 91.67% purity is below Canada's 99.5% threshold for GST/HST-exempt precious metals. Sovereigns may therefore attract GST/HST.

Australia

• GST: The 91.67% purity is below Australia's 99.5% threshold for GST-exempt investment gold. ATO guidance on foreign legal tender coins at lower purities is nuanced, and Sovereigns may attract 10% GST.

European Union

• VAT: Exempt. Sovereigns are recognised investment gold coins under EU Directive 98/80/EC (post-1800 legal tender coins at 900+ fineness sold at no more than 80% above gold value).

South Africa

• VAT: Only gold Krugerrands are zero-rated in South Africa. Sovereigns would carry the standard 15% VAT.

1/10 oz Sovereign vs Fractional Gold Alternatives

The 1/10 oz Sovereign faces an unusual competitive position. Within the UK, its tax treatment is identical to the 1/10 oz Britannia: both are CGT-exempt, VAT-free UK legal tender. The choice between them comes down to purity preference, alloy characteristics, and brand affinity.

The 1/10 oz Britannia at 999.9 fine gold contains 3.11 grams of pure gold in a 3.13 gram coin. The 1/10 oz Sovereign at 916.7 fine also contains approximately 3.11 grams of pure gold but in a heavier coin due to the copper alloy. The Britannia's higher purity makes it IRA-eligible in the US and GST-exempt in Australia and Canada, advantages the Sovereign lacks. The Sovereign's 22 carat alloy is more durable and carries the historical cachet of the Pistrucci St George design.

Against the 1/10 oz Krugerrand, the comparison is between two 22 karat coins. Both use a gold-copper alloy (the Krugerrand's is slightly different, producing a more pronounced reddish tone). The Sovereign's critical advantage is CGT exemption in the UK. The Krugerrand has no face value, no legal tender status, and no CGT exemption anywhere.

For investors outside the UK who do not benefit from CGT exemption, the 1/10 oz Sovereign's 22 carat purity becomes a disadvantage. US investors are better served by the 1/10 oz American Eagle (IRA-eligible despite also being 22 karat, thanks to its special Congressional exemption) or the 1/10 oz Maple Leaf at 999.9 fine.

The Sovereign range excels most at the full and half Sovereign sizes, where historical pedigree, established dealer networks, and centuries of trading history create deep liquidity. The 1/10 oz is the newest and least established denomination in the family, and buyers seeking fractional Sovereign gold may find the Quarter Sovereign a more natural stepping stone.
