Bronze 20p – £232
Collectors go wild for rare 20 pence coins that were accidentally printed on a copper-coloured blank.
The error coins, produced in 1983, are thought to be one of the rarest around.
In September 2023 one flew off the market for a whopping £232 after receiving a total of 28 bids.
The Royal Mint confirmed at the time that the bronze 20p was due to an .
One seller is currently trying to flog theirs for £328 – but there is no saying how much it will actually go for.
Remember, a coin is only worth what people will pay for it.
And also bear in mind that many people selling on could be trying to scam you with decoy coins.
Sometimes it is best to meet your seller in person – in a public safe place – to secure a trustworthy transaction.
“New Pence” – 2p – £1,100
A from 1983 was accidentally printed with the words “new pence” rather than “two pence”.
That year, The Royal mint had begun transforming the “new pence” coin into the “two pence”.
This was because the UK switched to decimal currency in 1971, and this was chosen to avoid confusion with the old currency.
But a handful of coins were accidentally printed with the former name and are thought to have entered circulation during the transition.
A viral coin expert, who goes by @CoinCollectingWizard, on , has speculated: “If you find this rare coin you are looking at £1,000 plus.”
According to Changechecker.org, one coin sold for £1,100 in 2019.
Some are listed on right now for even higher prices – with one put on the site for £2,499.95.
However others have sold for much less on the site, so take this with a pinch of salt.
Olympic Aquatics – 50p – £3,766
The 2011 Aquatics 50p was designed to commemorate the 2012 Olympics.
Usually, the face of the swimmer is clearly visible on the coin rather than being indented by the waves.
However, around 600 of the pennies were misprinted with wave lines covering the entire surface.
If you have the collector's version of the coin, sealed in a purple and teal card, there is a chance yours is the rare variant.
On August 4, one sold on for a whopping £3,766.
And the Britannia Coin Company is currently auctioning one for £3,995 – almost 8,000 times its face value.
Lord Kitchener – £1 – £1,200
Some Lord Kitchener £2 coins from 2014 could be worth 500 times their normal price if they have a specific fault.
Usually, every £2 coin has “TWO POUNDS” beneath the portrait of on the other side.
But a small number of the coins were actually struck without this denomination.
It is unsure exactly how many there are out there – but they are thought to be very rare.
According to @CoinCollectingWizard, the error pound coins can sell for anywhere between £900 or £1,000, and even more at auction.
The Britannia Coin Company has previously auctioned theirs for £1,200.
Third Portrait – 5p – £161.78
A auction turned heads when a seller sold their five pence coin for a whopping 3,220 times its original price.
It came after the seller noticed the 5p, featuring the “Third Portrait” of and a crowned thistle on the reverse, had been printed on the wrong coin.
When advertising the listing, the seller predicted it had actually been printed on a Fiji cent.
They said at the time: “Based on weight, metallurgy, diameter, designer of portrait – it would be a close match.”
The reason for this has remained a mystery – but experts say the coin could sell for even more if there are others out there.
