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.

An arrangement of 17 brass instruments based on the sculpture 'Breathless' of Cornelia Parker accompanied by the blue 2012 London Olympic logo and a quotation from John Lennon and Paul McCartney, "All you need is love".

This coin celebrates British popular music which originated in the sixteenth and seventeenth centuries with the arrival of the broadside ballad. Then came the brass bands, followed by music halls and dance bands. In the early 1960's The Beatles arrived and set the standard for popular music.

'Breathless' is a work commissioned specially from the British artist Cornelia Parker for display in the new British Galleries. It was specifically designed to fill the oculus or open space newly created between the two floors of the Galleries in a corner. It is made of 54 defunct brass band instruments which have been squashed flat and hung from wires. They are designed to be seen from both above and below, with polished upper surfaces and tarnished undersides. the work is an attempt by the artist to explore such ideas of duality as silence/noise, upper class/lower class, and death/resurrection.

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".
