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.

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

The reverse features the crown of St. Edward above shields bearing the Royal Arms and the Coat of Arms of Prince Philip, separated by an anchor. The crown represents the Queen's formal role, being worn by her on state occasions, and the anchor symbolises Prince Philip's distinguished naval career.

Prince Philip's arms post-1949 comprise four quarters, Denmark, Greece, and Mountbatten, representing his ancestry, and Edinburgh, representing the territorial designation of his dukedom.
