A rare £2 coin coming up for auction in Wiltshire could be worth hundreds of pounds due to an error confirmed by The Royal Mint.

The coin, which was part of a collection produced in 2014 to mark 100 years since the outbreak of World War I, shows an image of Lord Kitchener used on recruiting posters during the war.

The collection itself is not particularly rare as around 5,720,000 copies of the coins were produced and distributed around the country.

But one avid coin checker spotted a version of the coin which was particularly unusual due to a tiny error.

"Usually, these coins have the words ‘TWO POUNDS’ on the headside, along with a portrait of Queen Elizabeth II," explained a spokesperson for RWB Auctions.

"But this example does not, making it highly collectable and generating national interest."

The extremely rare coin is going under the hammer in RWB Auctions' new auction house on Wednesday, February 14, along with a signed letter from The Royal Mint Museum's information and research manager confirming the mistake.

The current starting price sits at £600 and is expected to go for at least £800 if not more, as it is one of the rarest documented error coins in circulation.

"It's a truly rare modern error coin with only a handful of examples known," added the auction house spokesperson.

"Please check your coins - if the £2 denomination wording is missing you may also have a rare coin."
