Some of the coins minted in error have a one-off mistake in their design, with others part of a larger batch of coins that was produced with faults.

The Royal Mint makes up to four million coins a day, with more than 30 billion coins estimated to be in circulation in the UK today.

Some of the most valuable coins on change checking website Coin Hunter are worth a total of £3,154, it’s reported.

Colin Bellamy, who runs Coin Hunter, told The Mirror: “Keep an eye out for coin errors when you receive change – look for anything different or unexpected.

“If you have a coin and you’re not sure if it’s a mint error, join a Facebook coin group such as Coin Errors and upload a picture to find out if the coin is worth more than its face value.”

These silver two pence pieces – which look like a 10p – sells for roughly £600, The Mirror reports Bellamy as estimating.

But one of the rare coins previously sold for £1,357 – after a petrol station owner found it in a stash of pennies.

David Didcock struck it rich after unearthing it among a batch of new coins in Poole, Dorset, in 1988.

Coins that are the wrong colour can also be very valuable.

A bronze 20p, found by collector Dave Crosier, has been valued at £750, with coin’s edging more round than a standard 20p.

But tt’s said to be so rare it it may be the only one in circulation.

These all-yellow £2 coins could be worth up to £500, according to Coin Hunter, the Mirror reports.

Normal £2 coins have a steel-coloured inner disc, unlike this one from 2007.

But it’s not known how many of the rogue £2 coins are in circulation.

The date on this £1 coin has been printed incorrectly, possibly pushing up its value to £375.

But the tiny flaw is so hard to spot most people would miss it.

The design flaw is hard to spot and you may need a magnifying glass to find it.

Its “micro dates” on the outside of the coin shows the date 2017 – even though it was minted 2016.

Coins that are minted the “wrong way round” could be worth a few quid.

These error 2015 Britannia coins – with the Queen’s head the wrong wary round – could be worth up to to £75, Colin Bellamy told the Mirror.

Around 3.5million of the coins were released into circulation, but it’s not clear how many have the fault.

Undated 20p: £57

These undated 20p were minted without a printed date, with thousands said to be in circulation in 2008.

Following the Royal Mint’s decision to change its design, the date was moved from the back of the coin to the front.

But a batch of coins was minted with no date on either side, which Bellamy believes may be worth up to £50.

Shakespeare £2: £40

The Shakespeare Tragedies £2 coins were minted in 2016 to mark  mark the 400th anniversary of the death of the playwright.

Most coins bear the inscription “what a piece of work is a man”.

But others were made with the phrase “for King and country” in error, pushing up their price to around £40, Bellamy estimates.

It comes as Ebay sellers have been flogging Tokyo Olympics 50p coins for up to £100 with experts saying their value could rise even further.

Other coins that went into circulation are going for between £20 and £40 on the online auction site.
