Fourth crowned portrait of HM Queen Elizabeth II facing right, wearing the Girls of Great Britain and Ireland tiara, date above, denomination below. The mintmark (ČM) and engraver's initials below the portrait.

The Girls of Great Britain and Ireland tiara was a wedding present in 1947 from her grandmother, Queen Mary, who received it as a gift from the Girls of Great Britain and Ireland in 1893 on the occasion of her marriage to the Duke of York, later George V. Made by E. Wolfe & Co., it was purchased from Garrard & Co. by a committee organised by Lady Eve Greville. In 1914, Mary adapted the tiara to take 13 diamonds in place of the large oriental pearls surmounting the tiara. At first, Elizabeth wore the tiara without its base and pearls but the base was reattached in 1969. The Girls of Great Britain and Ireland Tiara is one of Elizabeth's most recognisable pieces of jewellery due to its widespread use on British banknotes and coinage.

No. 310 Squadron RAF was a Czechoslovak-manned fighter squadron of the Royal Air Force in the Second World War. The squadron was formed on 10 July 1940 at RAF Duxford. It was the first RAF squadron to be raised crewed by foreign nationals, in this case, escaped Czechoslovak pilots. Initially, it had two Squadron Leaders: the British Douglas Blackwood and the Czechoslovak Alexander Hess. Hess and many of his men had served in the Czechoslovak Air Force, escaped from Czechoslovakia after it was occupied by Nazi Germany, and then joined the French Air Force and fought in the Battle of France.

Initially the squadron was equipped with Hawker Hurricane I fighters. The squadron was operational in only a month and as part of 12 Group took part in the Battle of Britain as part of the Duxford Big Wing. The squadron claimed 37½ victories in the battle.
