Fourth crowned portrait of HM Queen Elizabeth II facing right, wearing the Girls of Great Britain and Ireland tiara.

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.

ELIZABETH II DEI GRATIA REGINA FIDEI DEFENSATRIX means Elizabeth II, by the grace of God, Queen and Defender of the Faith.

Two figures fencing, with the London 2012 logo above and the denomination, "50 PENCE", below.

The fencing competitions at the 2012 Olympic Games in London were held from 28 July to 5 August at the ExCeL Exhibition Centre. Ten events (six individual, four team) were contested. Fencing, also called Olympic fencing, is a sport in which two competitors fight using 'rapier-style' swords, the foil, the Epée, and the sabre, winning points by making contact with their opponent. Fencing was one of the first sports to be played in the Olympics. Based on the traditional skills of swordsmanship, the modern sport arose at the end of the 19th century, with the Italian school having modified the historical European martial art of classical fencing, and the French school having later refined the Italian system. There are three forms of modern fencing, each using a different style of weapon and different rules, and as such the sport is divided into three competitive scenes: foil, épée, and sabre.

Competitive fencing is one of five activities which have been featured in every one of the modern Olympic Games, the other four being athletics, cycling, swimming, and gymnastics.

The London 2012 Summer Olympics logo is four abstract shapes placed in a quadrant formation spelling out "2012". The word "London" is written in the shape representing the "2", while the Olympic rings are placed in the shape representing the "0".
