In 2010, to commemorate the 70th Anniversary of the Battle of Britain, the Royal Mint released on behalf of Alderney a Limited Issue Battle of Britain £5 Five Pound Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse portrays a Supermarine Spitfire in flight while the obverse features 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.
