In 2018, to celebrate the Royal Wedding of Prince Harry and Meghan Markle, the Royal Mint released a Limited Issue Royal Wedding Piedfort £5 Five Pound Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse features a portrait of Prince Harry and Meghan Markle with the dates 19th May 2018 while the obverse features the Fifth Portrait of Queen Elizabeth II both designed 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.
