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.

Depicts the moment of a baton handover in a relay race. The hand holding the baton descends from top right, above a sweeping UK flag which twists to become the flag of Brazil below the hand reaching up from bottom left to take the baton. The London 2012 Olympic logo is at the very top of the coin.

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".

In contrast to the opening ceremonies, many elements of the Olympic closing ceremonies gradually developed more by tradition than official mandate. The president of the Organizing Committee makes a speech before closing the Olympics by saying: And now, I declare the Games of the [ordinal number of Summer Olympics] Olympiad closed. In accordance with tradition, I call upon the youth of the world to assemble four years from now in [name of next host city] to celebrate the Games of the [subsequent ordinal number of Summer Olympics] Olympiad.
