Brits have been told to “always” check a certain 50p coin in case it is a highly sought after version. This piece could be worth more than £40,000 it’s been claimed.

Among collectors some coins are particularly valuable. This is usually linked to their rarity, with coins with low mintages among those most sought after.

Coins bearing unusual errors can also be prized for this reason. With this in mind, an expert revealed that a specific 50p could be “worth a fortune”.

In a video uploaded to social media platform TikTok, an expert known as the Coin Collecting Wizard, highlighted what is known as the Brexit 50p.

This coin is distinguished by the phrase “peace, prosperity and friendship with all nations” on its reverse – the tail side. On its head side is the image of Queen Elizabeth II.

The coin was struck to mark the date when Britain departed the EU on January 31, 2020. However, several of these coins were manufactured before this date, bearing what is now an incorrect date. 

This occurred because Brexit had originally been scheduled to happen the year before. Consequently, the particular dates you want to discover are March 29, 2019, or October 31, 2019.

He explained: “This 50 pence could have a rare error worth of fortune. A small number of Brexit 50 pence coins featuring the incorrect leaving date were produced by the Royal Mint.

“The coin was originally due to be released in March 2019,  but due to setbacks with Brexit was pushed to January 2020. It is not yet known how many of the Brexit coins were produced, with the Treasury only confirming that some were made for test purposes.”

In the video he showed an image of one of these coins from March 29, 2019 saying this is the one to “look out for”. “So always check your Brexit 50p as you never know,” he said.

“We do not know whether the coins have made it into the hands of the general public and suspect they’re being held back by the mint. There are many collectors out there who would pay a premium for the Brexit coin with an incorrect date.”

In a previous video, the Coin Collecting Wizard noted that a Brexit coin with the wrong date could be worth £40,000. Earlier this year, it was revealed that two copies with the October date had been discovered.

Gregory Edmund, a coin specialist from Spink & Son auction house, told The Telegraph that if the coins went up for auction he would expect them to fetch more than £40,000. He commented to say: “Ever since the official London Gazette notice for the 2019 Brexit 50 pence has existed, I have wondered if survivors of the one million cancelled coins would one day surface.

“Given the extremely stringent security at the Royal Mint, to suddenly have two examples survive, and be available for study at the same time, is a unique opportunity. This truly feels like my Charlie Bucket moment discovering the numismatic Golden Ticket.”

A thousand trial coins were made to mark the first exit date of March 29, 2019. And around a million of the October coins were thought to be melted down and recycled.
