A piedfort is an unusually thick coin, often exactly twice the normal weight and thickness of other coins of the same diameter and pattern. Piedforts are not normally circulated, and are only struck for presentation purposes by mint officials (such as patterns), or for collectors, dignitaries, and other VIPs.

Following the announcement of the passing of His Royal Highness Prince Philip, Duke of Edinburgh on 9 April 2021, The Royal Mint has created a coin to celebrate his life and legacy.

To honour Prince Philip’s philanthropic legacy, The Royal Mint will donate £50,000 from the sale of the coins, to be split between The Duke of Edinburgh’s Award in the UK and The Duke of Edinburgh’s International Award Foundation.

Prince Philip, Duke of Edinburgh (born Prince Philip of Greece and Denmark; 1921–2021), was a member of the British royal family as the husband of Elizabeth II. The longest-serving consort of a reigning British monarch and the longest-lived male member of the British royal family, he retired from his royal duties on 2 August 2017, aged 96, having completed 22,219 solo engagements and 5,493 speeches since 1952. Philip had four children with Elizabeth: Prince Charles, Princess Anne, Prince Andrew, and Prince Edward. A keen sports enthusiast, Philip helped develop the equestrian event of carriage driving. He was a patron of over 800 organisations and served as chairman of the Duke of Edinburgh's Award scheme for people aged 14 to 24.

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.
