In 2022 to celebrate the Queen's Platinum Jubilee, the Royal Mint released a very Limited Issue Platinum Jubilee Piedfort £5 Five Pound Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse design features a Royal Mantle as a surround as used on coinage of William IV with 1952 - 2022 and an edge inscription ‘SERVE YOU ALL THE DAYS OF MY LIFE’ inspired by Her Majesty’s 1952 Christmas message.
The obverse design depicts Her Majesty Queen Elizabeth II on horseback reminiscent of previous jubilee designs.
Both the reverse and obverse designs have been designed by John Bergdahl.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
Piedforts are coins which have been especially struck on thicker than normal blanks.
As their name suggests they are closely associated with France, where from the twelfth century, they were apparently issued by the Kings as presentation pieces.
In Britain the practise of striking piedforts is later and less frequent, but medieval and Tudor examples are known.
