New coins featuring the portrait of King Charles have been revealed, with a 50p carrying his image entering general circulation within weeks.
BBC News was given a first glimpse of the 50p and a commemorative £5 Crown which include an image of the King by British sculptor Martin Jennings.
The coins follow centuries of tradition with the monarch now facing left - the opposite way to his predecessor.
As with previous British kings, and unlike the Queen, he wears no crown.
King Charles personally approved the effigy, and was understood to be pleased with the likeness.

The coins will be sold to collectors by The Royal Mint from early next week. The 50p coin will be available for general use well before the end of the year, distributed according to demand by banks, building societies and post offices.
They will co-circulate with coins featuring the late Queen, so those 27 billion coins will still be accepted in shops.
Anne Jessopp, chief executive of The Royal Mint, said that coins generally lasted for 20 years, so both Queen Elizabeth and King Charles coins will be in circulation together for many years to come.
From the start of next year, coins from the 1p to the £2, which we use in day-to-day life, will be minted carrying the same image of King Charles. They will be sent out when needed to replace damaged and worn older coins and to cover any extra demand.
"People should not worry if they have coins with the Queen on. We will keep those coins in circulation," Mrs Jessopp said. "We are seeing people moving to different forms of payment, but people really like to use coins as well for lots of different reasons."
The official portrait was designed to give an accessible look to the King, and the same is true of the inscription.
Previous British monarchs have been denoted on the inscription using the Latin version of their name. However, the new coins say Charles III rather than Carolus.
The full inscription surrounding the effigy reads "CHARLES III • D • G • REX • F • D • 5 POUNDS • 2022", shortened from Latin, which translates to "King Charles III, by the Grace of God, Defender of the Faith".
The reverse of the new £5 coin shows two new portraits of the Queen, charting her journey from a young monarch to a long-standing head of state.
On the 50p coin, the reverse is a copy of the design used on the 1953 Crown struck to commemorate the Queen's coronation.
King Charles's portrait is the first coin design undertaken by Martin Jennings, but his public sculptures include poets John Betjeman, in St Pancras Station in London, and Philip Larkin in Hull.
He used photographs to come up with the design, rather than the King sitting for a specific portrait.
"It is the smallest work I have created, but it is humbling to know it will be seen and held by people around the world for centuries to come," he said.
The coins will be struck at The Royal Mint's site at Llantrisant, south Wales, where the official coin maker - and Britain's oldest company - moved to accommodate the decimalisation process in 1967.
Before decimalisation, it was common for people to carry coins featuring different monarchs in their pockets.
A memorial coin range to commemorate the life and legacy of Queen Elizabeth, including the £5 Crown, will be put on sale by The Royal Mint on Monday.

What is the Royal Mint?
- It is one of the oldest companies in the world, striking its first coin in the late 9th Century, during the reign of Alfred the Great
- The Mint was based inside the Tower of London for most of its existence, but since the late 1960s its home has been Llantrisant in Rhondda Cynon Taf
- The current facility was opened by Queen Elizabeth II on 17 December 1968, just in time for the massive task of replacing the billions of coins in circulation ahead of decimalisation
- There are more than 27bn coins in circulation in the UK, with the Mint issuing around one billion new coins every year - although this figure does fluctuate.
Separately, people are being urged to check whether they have any paper banknotes at home, as they will be withdrawn from circulation by the weekend.
Shops are permitted to no longer accept £20 Adam Smith and £50 notes featuring the portraits of Matthew Boulton and James Watt from Saturday.
In addition to these Bank of England banknotes, paper £20 and £50 notes issued by Clydesdale Bank, Royal Bank of Scotland and Bank of Scotland will also be withdrawn on the same date.
The paper £20 notes issued by Bank of Ireland, AIB Group, Danske Bank, and Ulster Bank in Northern Ireland will also be taken out of circulation.
Anyone who misses the deadline should still be able to exchange the old notes at their bank.
