In 2015 to commemorate the 75th Anniversary of the Battle of Britain, the Royal Mint released a special Limited Issue Battle of Britain 50p Fifty Pence Gold Proof Coin struck in solid 22 Carat Gold.
The reverse designed by Gary Breeze depicts airmen scrambling to their planes while 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.
