About the Britannia and Liberty Gold
A Historic Collaboration Between Two National Mints
The Britannia and Liberty coin is the product of the first-ever collaboration between The Royal Mint (UK) and the United States Mint, launched in 2024. The two mints, with a combined history spanning over a thousand years (the Royal Mint was founded around 886 AD, the US Mint in 1792), had never previously produced a joint coin.
The reverse design was created by Royal Mint Chief Engraver Gordon Summers (Britannia) and US Mint Chief Engraver Joseph Menna (Liberty). Both allegorical figures appear on the same coin for the first time, depicted in opposing profile portraits, described as resembling the faces on a playing card, giving each figure equal prominence. Liberty carries a torch and is adorned with stars; Britannia wields a trident and wears a Corinthian helmet.
The Royal Mint versions are UK legal tender carrying King Charles III on the obverse (portrait by Martin Jennings). The 1 oz gold coin has a £100 face value and a global mintage of just 11,000 for the 2024 issue, making it significantly rarer than the standard Britannia (with estimated mintages exceeding 150,000 annually). The programme continued into 2025 with new denominations including a 1/4 oz gold coin and a four-coin fractional gold proof set.
For UK buyers, the Royal Mint versions carry both CGT exemption and VAT exemption on gold, putting them on identical tax footing with the standard Britannia. The US Mint issued its own versions: a $100 gold coin and a silver proof medal (no denomination, not legal tender). The US gold coin is likely classified as numismatic rather than bullion, with IRA eligibility uncertain and requiring custodian confirmation.

A 2025 fractional gold proof set contained 1 oz, 1/2 oz, 1/4 oz, and 1/10 oz coins.
The US Mint reverse depicts the sun rising over the Atlantic Ocean, framed by two shores. A Great Basin Bristlecone Pine tree on the western shore represents the US, and an English Yew tree on the eastern shore represents Britain, symbolising the transatlantic alliance.
Britannia and Liberty Tax Treatment
Tax treatment depends on which mint produced the coin and the buyer's jurisdiction.
United Kingdom (Royal Mint versions)
The Royal Mint gold coins are UK legal tender with sterling face values (£100 for 1 oz, £25 for 1/4 oz). As UK legal tender gold coins, they are exempt from both VAT and Capital Gains Tax for UK residents. This gives them the same tax advantages as the standard gold Britannia and the gold Sovereign. Silver versions carry £2 face value and are CGT-exempt as legal tender, but silver is subject to 20% VAT on purchase in the UK.
United Kingdom (US Mint versions)
The US Mint gold coin ($100 face value) qualifies for VAT exemption as investment gold at .9999 purity. It is not UK legal tender, so capital gains are subject to CGT above the annual exempt amount.
United States
The US Mint gold coin carries $100 legal tender status but is classified as numismatic rather than bullion. IRA eligibility is uncertain and should be confirmed with an IRA custodian. The silver medal has no denomination and no legal tender status. Royal Mint versions purchased in the US are foreign legal tender gold coins at .9999 purity; they may qualify for IRA inclusion, but this is a new product and custodian confirmation is recommended. No federal sales tax applies; state exemptions vary.
European Union
Gold versions from both mints qualify for VAT exemption as investment gold under Directive 98/80/EC, given the .9999 purity.
Canada and Australia
No special tax status beyond the standard investment gold exemptions (GST/HST-exempt in Canada at 99.5%+ purity; GST-exempt in Australia at 99.5%+ purity). Standard import duties apply on foreign bullion.
Britannia and Liberty vs Standard Britannia, American Liberty, and Libertad
The most immediate comparison is with the standard Royal Mint Britannia. Both are Royal Mint UK legal tender gold coins at .9999 purity with CGT and VAT exemption for UK buyers. The Britannia and Liberty's 11,000 mintage (2024) positions it as a far more exclusive coin compared to the Britannia's production runs exceeding 150,000 annually. Premiums are notably higher, reflecting the limited mintage, collaborative design, and collector interest. For buyers focused on gold accumulation at the lowest premium, the standard Britannia is the clear choice. For buyers who value rarity, historical significance, and the potential for collector appreciation, the Britannia and Liberty offers something the standard Britannia does not.
The American Liberty High Relief gold coin shares a similar collector-oriented positioning from the US Mint side. Both are .9999 fine gold with $100 face values and limited mintages. The Britannia and Liberty adds the unique angle of a cross-mint collaboration, something neither programme achieves alone.
Both the Britannia and the Mexican Libertad feature national allegorical figures, but the Britannia and Liberty is unique in combining two national symbols from different countries on one coin. The symbolic design, two allied nations' allegorical figures sharing a coin face, was timed to reinforce the Anglo-American "special relationship" and represents a genuinely unprecedented event in the history of sovereign minting.
The 2024 Royal Mint gold version sold out relatively quickly, confirming strong collector demand. NGC (Numismatic Guaranty Corporation) offered special designation labels for the 2024 issues, further reflecting their collector significance. Whether the programme continues beyond 2025 has not been confirmed.
Britannia and Liberty Gold: frequently asked questions
-
The Britannia and Liberty is the first-ever joint programme between The Royal Mint (UK) and the United States Mint, launched in 2024. Each coin places Britain's Britannia and America's Lady Liberty in opposing profile on the same reverse, designed by Royal Mint Chief Engraver Gordon Summers and US Mint Chief Engraver Joseph Menna. The series is available in both gold and silver across multiple denominations.
-
The 2024 Royal Mint 1 oz gold bullion coin had a mintage of 11,000. The 2024 US Mint 1 oz gold coin was limited to 10,000, while the US Mint silver proof medal had a mintage of 75,000. The 2025 Royal Mint 1 oz silver bullion coin has a stated mintage of 50,000. Proof and collector sets have their own separate mintage limits.
-
Like all bullion coins, the price is anchored to the underlying metal spot price, plus a dealer premium. Because the Britannia and Liberty carries lower mintages than standard Britannia coins, premiums tend to be higher. We track 14 listings across 13 dealers; the table above shows the current spread.
-
Royal Mint versions carry the same four security features as the standard Britannia: a latent image that alternates between a padlock and trident when tilted, surface animation produced by picosecond lasers, micro-text reading "DECUS ET TUTAMEN" around the design, and tincture lines on Britannia's shield. These are visible without any tools by rotating the coin under direct light.
-
It is the first coin jointly produced by The Royal Mint and the United States Mint, a collaboration without historical precedent between two sovereign mints. The design places the national allegorical figures of both countries on one reverse, and the 2024 release was timed to mark the Anglo-American alliance, giving it both numismatic and diplomatic significance.
