Brits should keep an eye out for rare minting errors on their coins which could make their loose change worth a small fortune. These coins are worth more money than their set value because very few of them make it into circulation, which makes them valued for collectors.

Coin errors include blank spaces, blemishes or misprinted digits. The chances are that if you notice a coin in your wallet doesn’t quite look right, then it could be worth a bit of cash. In fact, some rare minting errors can increase a coin’s value by over 1,000 times.

One rare coin to keep a look out for is a 20p that was accidentally printed on a copper-coloured blank. They were produced in 1983 and are considered one of the rarest around.

One was sold on eBay in 2023 for a huge £232. It received a total of 28 bids before finally being sold.

There is also a rare 2p coin from 1983 that was accidentally printed with the words “new pence” rather than “two pence”. Some experts claim this coin could sell for £1,000, but others are currently available for less.

The value of the rare coins depends on a number of factors, including their condition and demand. If you think you’ve got a rare coin, you should contact The Royal Mint’s Collector’s Service who will authenticate and value it.

If the coin does turn out to be worth a bit of money, there are three main options to sell it. These are at an auction, on eBay or on Facebook Marketplace.

An auction can be organised with The Royal Mint’s Collectors Service, but it does cost money. Whereas eBay and Facebook Marketplace are free to list your coins.

However, sellers using these two methods are urged to use decent pictures to make sure the coin sells for the best price possible. They are also advised to check previous sales to check they don’t get ripped off.
