BRITS are being urged to check their spare change – as it’s revealed they could be sitting on HUNDREDS of pounds.

A £1 coin could rake in over £200 after an error made it extremely valuable, but you’ll need to be eagle-eyed to spot it.

This error coin was made entirely of real gold and went under the hammer for an eye-watering £250

The difference between the rare piece and a regular pound coin is its colour.

Most £1 change is made using silver Nickle covered with a gold-looking Brass mixture coating on top.

However, this error coin was made entirely of real gold and went under the hammer for an eye-watering £250 on eBay.

Change Checker coin expert, Kate Morgan, said: “One explanation for the supposed ‘error’ could be that the coin missed the plating stage during production.”

There have also been several £2 coins discovered with the same problem.

These were incredibly valuable as there were only four or five in circulation, as confirmed by The Royal Mint.

If a coin has a low mintage, meaning there weren’t many made, they are usually worth more money.

And, if a piece was manufactured with a mistake or has a unique serial number, then it can also be worth more than expected, as proven by the solid gold £1.

This comes after a special 50p coin was uncovered that could be worth £300 – if you can spot an unusual number combination.

Meanwhile, an “exceptionally rare” £5 note has been found and now sold for an eye-watering price.

The banknote dating back to July 12, 1900 has been bought at auction for £32,000 – 6,400 times its original value.

How to check if your small change is worth anything

Online tools from change experts like Coin Hunter are helpful to see how much your coins could rake in.

You can also go on Change Checker’s latest scarcity index update to see which are the most valuable today.

If you have spotted a special or rare coin and want to know how much it could fetch, have a look on eBay.

The online marketplace is great for searching the full coin name, selecting the “sold” listing, then opting for the “highest value” filter.

But remember, coins are only really worth what someone is willing to pay for them.

This comes as five of the rarest coins and notes worth up to £3,600 were revealed – do you have one in your wallet?
