The Royal Mint issued a Special commemorative 50 Pence in 1994 to celebrate the 50th Anniversary of D-Day. This was, of course, the day that we invaded Europe and the start of the long battle to defeat the Germans which set Europe Free. The 50 Pence at that time was a much larger coin and it showed the design off to its fullest. You have a squadron of planes and gliders attacking with ships below getting ready to off load the soldiers. The Mint also made a Special Collectors edition. Struck in Proof Sterling Silver they are now no longer made, the 50p has been replaced by a much smaller coin. Supplies are limited and each coin comes in a protective capsule as issued by the Mint.
