The Gold Britannia is the United Kingdom’s flagship bullion coin, and the 2026 issue delivers the modern version in full: 1 troy oz of .9999 fine gold, a £100 face value as UK legal tender, and the Royal Mint’s advanced security features struck into the design itself. Nearly four decades after its 1987 debut, the Britannia remains one of the most liquid gold coins in the world.
Key Features:
- Purity and Weight: .9999 fine gold, 1 troy oz
- Metal Type: Gold
- Obverse Design: Martin Jennings portrait of King Charles III with the 100 POUNDS denomination
- Reverse Design: Philip Nathan’s standing Britannia dated 2026, with trident, Union Jack shield, and olive branch
The reverse presents Philip Nathan’s Britannia at the windswept shoreline she has guarded since the series began. She strides forward in a Corinthian helmet, gown and cloak streaming behind her, an upright trident in her right hand while her left holds an olive branch against a shield bearing the Union Jack. The inscriptions BRITANNIA 2026 and 1 OZ 999.9 FINE GOLD circle the rim, with the motto DECUS ET TUTAMEN, “an ornament and a safeguard,” worked in fine micro-text within the design.
The obverse carries Martin Jennings’ left-facing effigy of King Charles III surrounded by CHARLES III D G REX F D and the 100 POUNDS face value.
Both faces sit on the Royal Mint’s guilloche security field, a radial pattern of engraved pixels that shimmers as the coin tilts and functions as an anti-counterfeiting measure alongside the micro-text and precision surface animation, technology the Mint bills as making the Britannia the world’s most visually secure bullion coin. Each 2026 coin arrives in Brilliant Uncirculated condition with the British government’s guarantee of weight and purity.
Sovereign backing, four-nines purity, cutting-edge security, and instant recognition anywhere gold trades: the Britannia checks every box an ounce can. Order the 2026 1 oz Gold Britannia today.
