Treasures of all shapes and sizes are listed on eBay each day, with many coin collectors putting their “rare” items up for sale.
Recently, a seller, known as “paul3670114”, unveiled a 2014 £1 piece, which is said to be “very sought after and very rare”.
The item is thought to stand out due to it being a trial piece, which contains an error.
It’s up for auction at a whopping minimum sale price of £300, but it’s yet to be seen whether buyers are willing to make a bid.
There’s little description on the listing about the coin, other than the seller penning: “Very rare error £1 coin”.
However, it’s not immediately clear where the so-called error appears.
A number of photos have also been posted, so interested parties can take a closer look.
On one side, there is a depiction of Queen Elizabeth II’s head.
While the picture is fairly blurry, the reverse is thought to show the logo of The Royal Mint, as well as the words: “Trial piece”.
Trial coins are created in order to see if a new design will work when it comes to the pieces going into circulation.
But, despite them being listed for large sums of money, Royal Mint insist these types of change should be returned.
They told Chards.co.uk: “These samples have been issued under strict ‘terms and conditions’ and remain the property of the Royal Mint at all times.
“Unfortunately, we are aware that some samples have been listed on auction sites, however, as per the terms and conditions agreed to by stakeholders at the point of purchase, samples should be returned to The Royal Mint.”
Back in 2014, two new coins were brought out, both of which had been designed by Timothy Noad, with one depicting the floral emblem of Scotland.
The other depicted the floral emblem of Northern Ireland – and they both had the spherical style of old pound coins – rather than the new 12-sided design.
The picture of this trial piece on eBay appears to show the coin having less of a rounded design, and instead seems to be more like the dodecagon of the latest £1 piece.
The seller “happybidder123” hoped to get a staggering £2,5000 for the coin – with buyers also paying £2.95 in postage.
However, according to the Royal Mint, approximately 17,649,000 of this particular type of 50p were made.
What’s more, Changechecker.org deem the piece to be “common” in the scarcity index – so it may not be worth such a high value.
Which are the rarest £1, £2, 50p, 20p, 10p and 2p coins?
Rarest £2 coins
The rarest £2 coin is the 2002 Commonwealth Games NI coin with 485,500 in circulation. This is followed by the 2002 Commonwealth Games Wales which has 588,500 in circulation.
Next up is the 2015 Navy, and there are 650,000 in circulation.
Rarest £1 coins
The most rare £1 coins are all part of a series celebrating the British capitals.
The rarest of these is the 2011 Edinburgh coin, with 935,000 in circulation. Of the 2011 Cardiff coins there are 1,615,000 in circulation, while the 2010 London coin has 2,635,000 in circulation.
Rarest 50p coin
The rarest 50p coin is the Kew Gardens coin, which is also the rarest coin in circulation. It there were only 210,000 minted.
The football Olympic 50p coin has 1,125,500 in circulation, and the wrestling coin has 1,129,500 in circulation.
It is not so easy to evaluate the rarest 20p coins, 10p coins and even 2p coins as exact circulation figures are not known.
However, various versions of the coins are known to sell for large sums.
These include the dateless 20ps, which are actually part of a run from 2008. There may be between 50,000 and 200,000 of these coins in circulation.
The 1983 ‘New Pence’ 2p coin can also sell for a huge sum, up to £650.
