In 2007 the Royal Mint released a very special L imited I ssue Piedfort Silver Proof 5 C oin C ollection which includes the Diamond Wedding £5 Five Pound Coin, Slave Trade and Act of Union £2 Two Pound Coins , Gateshead Millennium Bridge £1 One Pound Coin and the Scout Centenary 50p Fifty Pence Coin.
All the coins have the stunning obverse 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 practise of striking piedforts is later and less frequent, but medieval and Tudor examples are known.
