In 2010 to celebrate the London 2012 Olympic Games, the Royal Mint released a very Limited Issue Buckingham Palace £5 Five Pound Proof Crown Coin.
The reverse designed by Shane Greeves depicts Buckingham Palace and the Mall while the obverse design 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.
