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 jewelry 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.

Depicts a lantern and the Queen’s Keys, and a plan of the walls of the Tower which is split over the four coins in the collection unifying their designs.

At exactly 9.53 pm, the Chief Yeoman Warder, dressed in Tudor watchcoat and bonnet, and carrying a candle lantern donated by the Honourable Artillery Company in 1919, leaves the Byward Tower and falls in with the Escort to the Keys, a military escort made up of armed members of the Tower of London Guard. The Warder passes his lantern to a soldier, and marches with his escort to the outer gate. The sentries on duty salute the Queen’s Keys as they pass.

A1 2 helps to identify the keys, as others have A1 1 on them.

A special Tower mint mark features on an official UK coin for the first time (on the left).

A phrase from the poem Human Life of Samuel Rogers (1763–1855):

Went Sidney, Russell, Raleigh, Cranmer, More,
On into twilight within walls of stone,
Then to the place of trial;
