In 2014 to celebrate the 500th Anniversary of Trinity House, the Royal Mint released a very special Limited Issue Trinity House Piedfort £2 Two Pound Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse designed by Joe Whitlock Blundell depicts Trinity House while the obverse is the stunning portrait of Her Majesty Queen Elizabeth II by Ian Rank Broadley .
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 practice of striking piedforts is later and less frequent, but medieval and Tudor examples are known.
