A rare coin has sold for thousands of pounds on eBay.
The special 50p was made to mark the UK leaving the EU and one has sold for £15,000.
But you might be in luck to find yourself one too as there are 10 million Royal Mint Brexit 50ps still in circulation, the Mirror reports.

To mark the official Brexit date of January 31 2020, these special coins were created with the Queen's head on one side and other with a special engraving.
'Peace, prosperity and friendship with all nations' has been engraved with the date below.
10 million coins were released, but now many have ended up in the hands of collectors, meaning the price of those remaining has skyrocketed.
Two of these rare coins have sold on eBay for 30,000 x more their face value at £15,000 each.
Other ambitious sellers are asking for £50,000 on the auction website.
And other examples of the coins have sold this year for between £3,500 and £10,000.
But if you do find you own one of the special 50ps, be aware that you may be undercut when you try to sell it.
Some eBay sellers are listing the Brexit 50ps for a more wallet-friendly price of £1.35 - perhaps not realising the value of what they have.
ChangeChecker expert Alexandra Fiddons previously told The Mirror: "The 50p was teased for a long while before the UK's official exit from the European Union and when it was officially released into circulation, people were eager to snap them up for their own collections.
"This coin marks an incredibly significant moment in British history and it's possible that people who aren't usually interested in the hobby, may have been tempted to secure this 50p to commemorate the event forever."
Speaking on what makes a coin 'rare', she said: "Sometimes we see coins listed for prices well above their face value on the secondary market.
"Sometimes this is driven by low mintage figures, meaning there are fewer coins for people to collect, but it can also be driven by the popularity of the theme."
There is one other version of the Brexit 50p that is even rarer - and is worth much more than the 10 million in circulation.
Some of the Brexit 50p were minted two years ago with the date of October 31, 2019 - the original Brexit date, which ended up being missed.
Then-chancellor Sajid Javid had asked for three million of the coins to be made ready for this date, with another seven million to follow later in the year.
Around one million of the coins were made before the government realised it would miss the October 2019 Brexit date.
While most of the coins were melted down by the Royal Mint, some made it into the wider world.
If you are tempted to buy any second-hand coins from eBay, beware of fakes circulating.
