A rare 10p coin has sold for almost £104 on eBay because of a design flaw that makes it look dented.
Error coins are particularly valuable to collectors as they could be one of a handful, or even one a kind.
In this case, the 10p has a kink in the top left-hand corner which looks like someone has pressed down a section of the coin.
The seller claims this could be down to the coin being misstruck at some point during the Royal Mint minting process.
They said: “Rare certified 10p ten pence large 1980 coin ONLY ONE KNOWN mistrike. This was certified in 1987 by the Royal Mint and returned with the certificate and returned to my father.
“The coin will be sent special delivery tracked signed for and insured for the buyer. You will receive the coin and original certificate from the Royal Mint.”
The 10p sold for £103.51 exactly, plus £6.85 delivery, following a seven-day auction that started at just 99p.
A total of 19 bids were placed on the rare coin. You can see the eBay listing here.
