Brexit 50p enters circulation from Friday
Around three million Brexit 50p coins will start showing up in people's pockets and wallets when they enter banks, post offices and shops from Friday. Another seven million of the coins, minted to mark the UK's departure from the EU, will enter circulation later this year.
People who do not want to wait to spot a Brexit 50p in their loose change could go online instead and buy a commemorative coin.
The Royal Mint has produced versions for sale which range from £10 for a brilliant uncirculated 50p to £945 for a limited edition gold coin.
The Mint said it is the fourth time it has been involved in the production of a commemorative coin to mark the UK's relationship with the European Union.
It produced a coin when the UK joined the European Economic Community in 1973, created a design for the single market in 1992, and marked the UK's 25th anniversary of joining the EU in 1998.
Chancellor Sajid Javid previously gave people a first glimpse of the new coins.
The coins are dated January 31 - and the chancellor has said the coins mark the beginning of a "new chapter".
Mr Javid originally ordered production of the celebratory coins in advance of the previous departure date of October 31.
But the Brexit delay meant about a million coins had to be melted down and the metal put aside until a new exit date was confirmed.
The coins have already sparked controversy before entering circulation - and not just for political reasons.
Their inscription reads: "Peace, prosperity and friendship with all nations."
Author Sir Philip Pullman has called for the coins to be boycotted for not having an Oxford comma.
An Oxford comma is used after the penultimate item in a list of three or more items, so would be placed after the word "prosperity".
His Dark Materials author Sir Philip wrote on Twitter that the omission meant the coin should "be boycotted by all literate people".
Some other commentators have disagreed with Sir Philip, arguing the use of the comma is optional.
The punctuation mark takes its name from its use by the Oxford University Press (OUP).
On its use, the OUP's style guide states: "In a list of three or more items, insert a comma before the 'and' or 'or'."
Fiona McPherson, senior editor with the new words team on the Oxford English Dictionary (OED) said: "The Oxford comma, also known as the serial comma, is used before the final conjunction in a list of items.
"It is often an optional piece of punctuation, but there are occasions where its inclusion can help to avoid ambiguity."
As part of the launch of the coin, the Royal Mint Experience in South Wales is opening its doors for 24 hours on Friday to let people strike their own commemorative Brexit coins.
Tours for January 31 have now sold out, but visitors will have the opportunity to strike commemorative coins until February 12.
Speaking about producing the new coins, Leighton John, operations director at the Royal Mint, told the PA news agency: "We've always commemorated major events, so it's really great for us to be able to do this.
"And I think everyone will agree, whichever side of the argument you're on, it's a major event for the country."
