A rare 50p coin, known as the "Brexit" coin, could be worth £40,000, according to an expert. However, only coins featuring one of two specific dates are highly valuable.

Minted to commemorate the UK's departure from the EU on January 31, 2020, a limited number of these coins were produced with incorrect dates, originally intended for Brexit in the previous year. As a result, collectors are on the lookout for coins dated March 29, 2019, or October 31, 2019.

An expert known as the Coin Collecting Wizard, shared his knowledge on TikTok, explaining: "So let's start from the beginning. This coin is the Brexit 50p from 2020 and as you can see it clearly has the Brexit date at the bottom of the coin. But did you know there is another date out there on this 50 pence and only a few have ever been found?

"If you find the Brexit 50p coin in your change, which is most likely as millions were minted for circulation, then all you need to do is check the date at the bottom of the coin. If your date says 31st January 2020, then this is just the regular common version worth 50 pence, but if you are super lucky and find one with a date other than 2020, such as this one from October 2019, then you have just found a super rare error coin."
