Third crowned portrait of HM Queen Elizabeth II facing right, wearing the George IV State Diadem.

The George IV State Diadem, officially the Diamond Diadem, is a type of crown that was made in 1820 for King George IV. The diadem is worn by queens and queens consort in procession to coronations and State Openings of Parliament. The piece of jewellery has been featured in paintings and on stamps and currency. It can be seen in the Queen's Gallery at Buckingham Palace.

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

From 1985 to 1991 the head of Queen Elizabeth II was a slightly smaller size. From 1993 to 1997 the head was a slightly larger size. The change over was made part way through 1992 so there are two versions in this year. 1997 has small varieties in design of the portrait.

Three lions passant guardant representing England.

Royal emblems depicting lions were first used by the Norman dynasty, later a formal and consistent English heraldry system emerged at the end of the 12th century. The earliest surviving representation of an escutcheon, or shield, displaying three lions is that on the Great Seal of King Richard I (1189-1199), which initially displayed one or two lions rampant, but in 1198 was permanently altered to depict three lions passant, perhaps representing Richard I's principal three positions as King of the English, Duke of the Normans, and Duke of the Aquitaines. The coat of three lions continues to represent England on several coins of the pound sterling, forms the basis of several emblems of English national sports teams (although with altered tinctures) and endures as one of the most recognisable national symbols of England.

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.
