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.

A richly decorated Celtic-style cross, surmounted by the famous Broighter collar. At the centre of the design lies a pimpernel, the flower which flourishes around Lough Neagh.

The Broighter Gold or more correctly, the Broighter Hoard, is a hoard of gold artefacts from the Iron Age of the 1st century BC that were found in 1896 by Tom Nicholl and James Morrow on farmland near Limavady, in the north of Ireland (now Northern Ireland). The hoard includes a 7-inch-long (18 cm) gold boat, a gold torc and bowl and some other jewellery. A design from the hoard has been used as an image on the 1996 issue of the Northern Ireland British one-pound coins.

The coin’s edge inscription is in Latin ‘DECUS ET TUTAMEN’ which may be translated as an ‘ornament to safeguard’. This inscription refers to itself, as it is decorative and protects the coin from being easily counterfeited.
