1/10 oz Britannia Charles III 2026 — British gold bullion coin from The Royal Mint with CGT-free status
1/10 oz Britannia Charles III 2026 is a gold bullion coin from The Royal Mint with a fineness of 999.9/1000 and a mass of 3.11 g of fine gold, belonging to the British flagship series launched in 1987. The 2026 vintage is the third full production year with the portrait of King Charles III by Martin Jennings, combined with the Britannia motif by P.J. Lynch from 2018. The coin has a face value of 10 GBP and full legal tender status in the United Kingdom.
The 1/10 oz Britannia is distinguished by its CGT-free status for UK tax residents — exemption from Capital Gains Tax resulting from full legal tender status in the UK. This status, together with The Royal Mint's 4-tier security system (radial sunburst, micro-print, latent feature and tincture lines) introduced for the 2021 vintage, makes Britannia one of the technically most secure bullion coins in the 1/10 oz segment.

History of the Britannia
Britannia as a symbol of Great Britain has its roots in coins of the Roman Empire — it was already minted during the reign of Emperor Hadrian (2nd c. AD) on provincial coins of Roman Britain. The modern series of Britannia gold coins from The Royal Mint was launched in 1987, twenty years after the Krugerrand (1967) and eight years after the Maple Leaf (1979). The introduction of the series was Britain's response to the growing interest in the global bullion market from classic national coins.
The first Britannia issues from 1987-2012 were struck in the Crown Gold alloy of 916.7/1000 fineness (22 karat), in line with the traditional British Sovereign standard used by the Royal Mint since 1817. In 2013 the Royal Mint raised the fineness to 999.9/1000 (.9999) — matching the then-competing series Maple Leaf (.9999), Kangaroo (.9999) and Vienna Philharmonic (.9999). The decision required a change of minting technology from alloy to pure gold.
The Royal Mint is the world's oldest active mint — its beginnings reach back to around 886 AD, when King Alfred the Great founded the London Mint. LBMA Good Delivery accreditation has been maintained since 1750, making it one of the oldest active accreditations in global bullion trading. The current location of the Royal Mint is Llantrisant in Wales, where the mint was relocated from London in 1968.
The 1/10 oz Britannia format was introduced in 1987 as one of the four original sizes of the series (1/10, 1/4, 1/2 and 1 oz). This format corresponds to the fraction of 1/10 troy oz — 3.11 g of fine gold — and allows regular accumulation with a smaller one-off outlay than the 1/4, 1/2 or 1 oz formats. The diameter of 16.5 mm is comparable with competing 1/10 oz coins: Maple Leaf 1/10 oz (16 mm) and Vienna Philharmonic 1/10 oz (16 mm).
The CGT-free status of the Britannia results from the fact that all coins with a GBP denomination minted by the Royal Mint are classified as legal tender in the United Kingdom, and British tax law exempts legal tender from Capital Gains Tax. The same status applies to Royal Mint gold Sovereigns. The CGT-free status applies to UK tax residents — for persons outside the UK the tax rules of their country of residence apply.
Obverse — portrait of Charles III
The obverse of the 1/10 oz Britannia 2026 presents the portrait of King Charles III by Martin Jennings, adopted by The Royal Mint in 2022. It is the first official portrait of the new monarch, approved by the King after his accession to the throne in September 2022. The portrait shows Charles III facing left — in keeping with the heraldic tradition of changing the direction of the portrait between successive monarchs (Elizabeth II faced right).
Around the portrait is the inscription CHARLES III D G REX F D (a Latin abbreviation meaning "Charles III, by the grace of God King, Defender of the Faith"), the face value 10 POUNDS and the year of minting 2026. The 2026 vintage is the third full production year of the Britannia with the portrait of Charles III — without the "first vintage" premium that characterised the 2024 issues (8-15% collector premium).
Reverse — P.J. Lynch's Britannia and security features
The reverse of the 1/10 oz Britannia presents the figure of Britannia — the allegorical personification of Great Britain — in a design by Patrick James Lynch (P.J. Lynch) from 2018. Lynch designed Britannia in a defensive stance, with Neptune's trident in her left hand, a shield with the British flag motif in her right hand, and a helmet on her head. Around the figure is the inscription BRITANNIA and the mass designation: 2026 1/10 OZ. FINE GOLD 999.9.
Since the 2021 vintage, The Royal Mint has introduced a four-tier security system placed on the reverse surface: (1) radial sunburst — radiating diffraction patterns around Britannia, visible at different angles of inclination, (2) micro-print — micro-text "DECUS ET TUTAMEN" (Latin for "ornament and safeguard"), (3) latent feature — hidden element changing appearance under light, (4) tincture lines — heraldic security lines on Britannia's shield. This system makes Britannia one of the technically most secure bullion coins in the 1/10 oz segment.
What to watch for when buying
The small surface of the 1/10 oz Britannia (diameter 16.5 mm, thickness 0.95 mm) means that even minor capsule abrasions can be visible on the coin — when buying, it is worth checking the condition of the original Royal Mint capsule as well as the visual assessment of the main surface (obverse/reverse). Minor traces of capsule contact are acceptable, but clear scratches on the field of Charles III's portrait or the Britannia figure should be a reason for complaint.
The 2026 vintage is the third full production year of the Britannia with the portrait of Charles III — without the "first vintage" premium characteristic of the 2024 issues (which, as the debut of Charles III on the coin, could carry a collector premium of 8-15% over the metal content). Customers interested in a specific vintage (e.g. 2024 as the first issue with Charles III) should consider buying a single vintage issue, which however has a higher price.
Bullion product status: Britannia holds LBMA Good Delivery accreditation and is classified as a bullion coin under Council Directive 98/80/EC (the 999.9 fineness significantly exceeds the required minimum of 900/1000). The 10 GBP face value confirms the full legal tender status in the United Kingdom, which is the basis for the CGT exemption for UK residents.
The CGT-free status applies exclusively to UK tax residents — for persons resident in other jurisdictions, any income from the sale of Britannia is subject to the tax rules of their country of residence.
