The new 12-sided £1 coin has gone into production a year before it starts to reach people's pockets.
The coins have started rolling off the production line at a rate of more than 4,000 a minute as Chancellor George Osborne announced they will enter circulation in March 2017.
When the new coin is introduced, there will be a six-month crossover period when the current round pound coins and the new pound coins are both in circulation.
I am delighted that the Royal Mint are now producing the most secure circulating coin anywhere in the world.

In tribute to the bravery of the troops who signed up in their thousands during the First World War, the Royal Mint has produced a coin to commemorate the war's centenary.
Only the second British £20 coin ever to be struck, the coin will be limited to 250,000 and will be available for collectors to purchase at face value.
Created by renowned scuptor John Bergdahl, the coin's design depicts the figure of Britannia watching over the first troops leaving for France at the start of the war in 1914.
“The centenary of the outbreak of the First World War is an occasion of such significance, it was important to us that this coin should takes its place in The Royal Mint’s programme of commemoration, remembering the bravery and sacrifice of those who answered the call to fight for King and country.”
The outbreak of World War One will be commemorated on 4 August.
The Royal Mint announced in April it is to open its doors to the public for the first time in its 1,000 year history.
The Royal Mint is opening its doors to the public for the first time in its 1,000-year history.
Britain's oldest manufacturing organisation started in the Tower of London, but since 1968 its headquarters have been in Llantrisant.
A grant from the Welsh Government means it can now build a new visitor centre. Our reporter Alexandra Lodge has been given a sneak preview of what people can expect to see.
The Royal Mint says it has been exploring plans for a visitor centre "for some time" after receiving large numbers of visitor requests each year.
The Royal Mint is a highly secure, Ministry of Defence-protected site which is not usually open to the public, with the exception of very special occasions and by invitation only.
We receive large numbers of requests to visit from members of the public every year and have been exploring the opportunity of a visitor centre for some time.
It gives us great pleasure to announce that this can now go ahead, and that people will be able to come here and see the work of one of Britain's national treasures.
Officials today announced plans to develop a £7.7 million visitor centre at the mint in Llantrisant.
It will be the first time in its 1,000-year history that the doors will be officially opened to the public.
The Royal Mint has unveiled plans to throw open its doors to the public for the first time in its 1,000 year history.
Officials today announced they are planning to develop a £7.7 million visitor centre at the mint in Llantrisant, South Wales.
Visitors will be allowed to look behind the scenes and see for themselves the people and processes responsible for the coins we use every day.
They will also have the opportunity to strike their own coin as a memento of their visit.
The project has been made possible after the Royal Mint secured a grant of £2.3million from the Welsh Government.
Construction of the visitor centre will begin this spring, subject to planning permission.
The Royal Mint in Llantrisant is striking a limited number of coins from the cargo of a British merchant ship - more than 70 years after it was originally meant to be delivered.
The SS Gairsoppa was carrying silver bullion bars over from India when it was torpedoed by a German U-boat in 1941. The ship and its cargo were eventually found 300 miles off the Irish coast in 2011. Dean Thomas reports.
The Royal Mint in Llantrisant is striking a set of silver coins from the bullion recovered from a merchant ship that sank during the Second World War.
British steam merchant ship SS Gairsoppa was torpedoed by a German U-boat in February 1941 off the coast of Ireland, whilst it was carrying a large shipment of silver bullion bars from India, destined for the Royal Mint.
The ship and its cargo were located in September 2011, and the silver bullion recovered by marine exploration company Odyssey Marine Exploration.
The bullion was three miles underwater - which they say made it the largest and deepest recovery of precious metal from a shipwreck in history.
Shane Bissett from the Royal Mint said: "The traditional Britannia coin design is the perfect image for the coins struck from SS Gairsoppa's long-lost cargo. We are so pleased to be able to bring these coins to the market at long last, albeit more than 70 years later than expected."
The Government has announced that a new 12-sided £1 coin will come into circulation in 2017, which the Treasury says will be "the most secure coin in circulation in the world."
The new coin will be made at the Royal Mint in Llantrisant.
We are thrilled to have the opportunity to support Her Majesty’s Treasury and work on such an exciting project, which could potentially change the way that coins are made in the future. The current £1 coin design is now more than thirty years old and it has become increasingly vulnerable to counterfeiting over time. It is our aim to identify and produce a pioneering new coin which helps to reduce the opportunities for counterfeiting, helping to boost public confidence in the UK’s circulating coins.
The Royal Mint works closely with HM Treasury, the National Crime Agency and the cash-handling industry who are committed to maintaining the integrity of the UK’s currency and exploring ways in which counterfeiting can be combated. Together we ensure that every effort is made to maximise opportunities to identify and withdraw counterfeit coins from circulation.
We are very proud to be recognised nationally in terms of providing innovative solutions on an international scale. We are already known as the world’s leading export mint, but iSIS confirms our place as leaders within our industry, as we continue to expand the boundaries of minting technology.
A new 12-sided one pound coin will replace the current one in 2017 and it should be much more difficult to forge.Read the full story ›
