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.

Three figures playing beach volleyball, with the London 2012 logo above and the denomination, "50 PENCE", below.

The volleyball tournaments at the 2012 Olympic Games in London were played between 28 July and 12 August. The indoor volleyball competition took place at Earls Court Exhibition Centre, in west London, and the beach volleyball tournament was held at Horse Guards Parade in central London.

Beach volleyball is a team sport played by two teams of two players on a sand court divided by a net. It has been an Olympic discipline since the 1996 Games. Beach volleyball originated at the Outrigger Canoe Club, on the shores of Waikiki Beach (in Hawaii, USA), and has achieved worldwide popularity.

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".
