Commemorating thhe 75th anniversary of the Battle of Britain in 1940. The first UK commemorative coin to feature three different obverses. Minted with the older and newer Queen's portrait. The proof coins also failed to feature a denomination mark, which was rectified for circulated versions. 
 
*Please note you are purchasing the circulated coin, featuring the Clark portrait and denomination marker - see photo*
 
Obverse: Ian Rank-Broadley or Jody Clark Portraits (see above)
Reverse: Depicting the three RAF fighters returning to their planes with the German Air Force overhead (designed by Gary Breeze)
