In 2019, to celebrate the 200th Anniversary of the Birth of Queen Victoria, the Royal Mint released a Limited Issue Queen Victoria Piedfort £5 Five Pound Silver Proof Coin struck in solid .925 Sterling Silver.

The reverse designed by John Bergdahl captures the bustle of Victorian life and features a Young Head Portrait of Queen Victoria as well as a number of innovations of the age.
The obverse features the Fifth Portrait of Her Majesty Queen Elizabeth II by Jody Clark.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.

Piedforts are coins which have been specially 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.
