A special edition £5 has been minted to commemorate the life of Prince Philip.
The Prince approved the design before his death at the age of 99.
It carries his head and bears the inscription:
“HRH The Prince Philip, Duke of Edinburgh 1921-2021.”
Chancellor Rishi Sunak unveiled the coin.
He said it was a fitting tribute to a man “who moved and inspired so many people around the world with his decades of service both to the nation and her majesty the Queen”.
He added:
“I’m proud to unveil the coin on Armed Forces Day, considering his distinguished naval career and unwavering dedication to our monarch and to his royal duties, and it is only right that he and the Queen are depicted together on both sides of it.”
The Royal Mint is striking the coin and is available from its website.
The Treasury said it can also be bought at post offices.
It is legal tender but has been designed as a limited-edition collectable or gift.
It will not be entering general circulation, the Treasury said.
Royal Mint chief executive Anne Jessopp said:
“Since the passing of the Duke of Edinburgh in April, many have commented that he led a life well lived.
“He was the longest serving consort in British history, and patron or president to over 750 organisations – including The Royal Mint Advisory Committee.
“The Royal Mint has marked significant Royal events for centuries and is honoured to unveil an original new coin which celebrates the life and legacy of a remarkable man.
“It feels fitting that this coin – which was personally approved by the prince – will also support the work of The Duke of Edinburgh’s Awards.
“The awards have benefited millions of young people since they were formed in 1956 and are perhaps Prince Philip’s greatest legacy.”
