Coins bearing the portrait of King Charles III will be gradually circulated from December.
The Royal Mint says his image will appear on the 50p coin first – and in keeping with tradition, King portrait facing left, facing the Queen.
A commemorative £5 coin has also been created featuring two new portraits of the late king on the reverse.
Nicola Howell, commercial director at the Royal Mint, said King Charles worked closely with sculptor Martin Jennings – and personally approved the effigy.
This was “to ensure there was a seamless empathetic way to end the queen’s reign and really herald the new reign of a new king”.
The Latin inscription around the dummy reads: “:: CHARLES III :: D :: G :: REX :: F :: D :: 5 POUNDS :: 2022” which means: “King Charles III, by Grace Scripture of God, Defender of the Faith.”
Dummies can be seen as softer and less regal than those of previous kings.
Chris Barker, from the Royal Mint, described the portrait as “stately and graceful, reflecting his years of service”.
He added: “I think if you look back at some of Elizabeth’s portraits – especially her first one by Mary Gillick – it was much more idealized.
“This is a lot of the man himself, of the individual, you see the lines of his face, the years of experience and that humanity come through.”
The reverse of the £5 anniversary coin features two new portraits of Queen Elizabeth II, showing younger and older images of the late monarch.
The design was created by artist John Bergdahl in collaboration with the Royal Mint.
It will form part of a broader memorial coin collection.
Ms Howell said: “We expect customers to start being able to receive the commemorative coin range from October and then we expect the 50p commemorative circulating coin to appear in every change. who could be from December”.
The back of the 50p features the original design that appeared on the 1953 Coronation Crown.
It was built to commemorate the coronation of Queen Elizabeth II at Westminster Abbey, and includes four quarters of the Royal Arms depicted in a shield.
In the middle of each shield are the symbols of the home countries: a rose, a thistle, a shamrock, and a leek.
All UK coins bearing the effigy of Queen Elizabeth II will remain legal tender and coins featuring the new King will be circulated alongside the mother’s coin.
Historically, it has been common to use coins with effigys of different kings, helping to reduce environmental impact and costs.
There are around 27 billion coins currently in circulation in the UK bearing an effigy of Queen Elizabeth II. They will be replaced from time to time as they become damaged or worn out and to meet the need for additional coins.
