The 2026 Great Britain Reverse Proof 1 oz Platinum Britannia & Liberty marks a defining moment for the series. It is the first-ever reverse proof issue and the final year of the current design, making it a true key-date issue.

Struck by The Royal Mint in .9999 fine platinum, the coin unites Britannia and Liberty in a historic transatlantic collaboration with the United States Mint.

Each coin is certified NGC REVERSE PF 70, the highest grade possible, and bears the desirable First Day of Issue designation. For added collectability, each label is hand-signed by Gordon Summers, Chief Engraver at The Royal Mint.

The reverse proof finish flips the traditional mirrored and frosted elements, creating a striking contrast and depth across the two allegorical figures.

Key Features:

• 1 oz Platinum Issue

• Mintage: 200

• All coins certified NGC REVERSE PF 70

• First Day of Issue (FDOI) designation

• Royal Mint label hand-signed by Gordon Summers
