Design Details
The Lion and Eagle Series celebrates the enduring alliance between the United Kingdom and the United States, highlighting the shared values, cooperation, and history that have defined the relationship between the two nations for more than a century.
The collaboration is further reinforced by the involvement of John Mercanti, whose work as Chief Engraver of the U.S. Mint helped shape many of America’s most recognizable coin designs. His artwork brings together the national emblems of both countries in a balanced and symbolic composition.
Struck on a large 5 oz silver planchet, the coin provides an expansive canvas for intricate detail and deep relief. The bold imagery and substantial silver weight make the coin attractive to both investors seeking larger bullion pieces and collectors interested in historically themed coin series.
Obverse
The obverse features the official portrait of King Charles III, designed by Martin Jennings. The King is shown in left-profile relief without a crown, following the traditional style used on modern British coinage.
Surrounding inscriptions identify the monarch and confirm the coin’s legal tender status with the £10 denomination, representing the issuing authority of Great Britain.
Reverse
The reverse design showcases two iconic national symbols: the American bald eagle and the British lion. The eagle stands prominently in the foreground looking to the right, while the powerful lion appears behind it in matching right-profile relief.
Together, these animals represent strength, unity, and the longstanding partnership between the United States and the United Kingdom, creating a striking visual tribute to the historic alliance between the two nations.
