1oz Gold Britannia Coins

First introduced in 1987, the Gold Britannia series has evolved into one of the Royal Mint’s most important bullion programmes. Since 2013, 1oz Gold Britannias have been struck in .9999 fine gold (24 carat), carrying a £100 face value and weighing 31.21 grams. Earlier issues from 1987–2012 were struck in 22 carat gold with copper or silver alloy content.

Designs typically feature Philip Nathan’s celebrated depiction of Britannia standing firm against the wind with shield and trident, alongside the official portrait of the reigning monarch. Modern bullion issues incorporate advanced Royal Mint security features, including latent imagery, surface animation, micro-text and tincture lines, helping make Britannia one of the world’s most secure bullion coins.

This category includes both bullion and proof 1oz Gold Britannia coins across multiple years and special editions, including Coronation releases and limited commemorative variants. Proof examples are struck using specially prepared dies for enhanced detail and mirror-like finishes, while bullion issues are produced to investment-grade Brilliant Uncirculated standard. Selected coins are presented in official Royal Mint packaging, with some professionally certified by PCGS or NGC for added collectability.

1oz Gold Britannias are especially popular among UK collectors and investors due to their legal tender status, Capital Gains Tax exemption for UK residents and strong global recognition.
