Gold Coin Britannia 1 oz Gold 2026 Proof

Britannia 1 oz Gold Coin 2026 Proof is an exclusive edition of one of the most esteemed series issued by The Royal Mint. The image of Britannia, present on British coins since Roman times, has for centuries symbolised naval power, resilience, and the continuity of the monarchy. The 2026 edition presents a new interpretation of this allegorical figure, blending tradition with contemporary mint craftsmanship.

The coin is struck in Au .9999 fine gold, weighing 1 ounce and measuring 32.69 mm in diameter. The £100 face value confirms its status as legal tender in the United Kingdom. A Proof finish guarantees a mirror-like field and frosted relief elements that reveal the finest details of the design. An exceptionally low mintage of 250 pieces gives this issue strong collector appeal. The coin is presented in an elegant mint case.

The reverse by Emily Damstry highlights Britannia’s timeless values—majesty, justice, and peace—also referenced in the inscription "MAJESTY, JUSTICE AND PEACE", inspired by Winston Churchill’s 1941 speech.

Obverse features the effigy of King Charles III by Martin Jennings. The monarch’s portrait is surrounded by the royal legend, the denomination £100 and the year of issue 2026, creating a classic, official composition characteristic of contemporary British coinage.

Reverse depicts Britannia in profile, holding a trident and a shield bearing the flag of the United Kingdom. The dynamic pose and billowing robes suggest a strong wind, while the churning waves and a lighthouse in the background emphasise her inseparable bond with the sea. The helmet ornament echoes the ocean’s waves, and the design is completed by the inscriptions "BRITANNIA 2026", "MAJESTY, JUSTICE AND PEACE" and the weight and gold purity.
