Three rare British coins are now worth a combined £72,900 - do you have any?

Co-founder of Coins Value, Chris Yang, explained that the first of these is an uncommon 2p that's especially valuable due to one glaringly obvious error

Three rare British coins could be hiding in your loose change - and they boast a combined value of 'up to £72,900'.

With many of us now using debit and credit cards for payments, it's likely that your loose change is getting tossed aside. But one specialist has now urged the public to keep an eye out for three coins in particular.

Co-founder of Coins Value Chris Yang said that a 1983 2p coin with the words 'New Pence' on it could be worth up to £700.

Another coin on the list is a 1933 penny which could fetch up to £72,000 - but good luck finding one of those.

Finally, a 2009 50p coin to mark the 250th anniversary of Kew Gardens could be worth up to £200.

Here's a closer look at each of these coins and how much they could be worth.

1. 1983 2p coin with 'New Pence'

According to Chris, due to a minting error, some 1983 2p coins were struck with 'New Pence' on the reverse rather than 'Two Pence'.

This mistake makes it quite valuable among collectors as it's not clear how many are still in circulation - although some suggest they were included in souvenir sets.

"If you find one of these coins, you can sell them at numismatic auction houses or on online marketplaces like eBay," Chris said.

He estimates that a 1983 New Pence coin can fetch between £500 and £700.

2. 1933 penny

During the 1930s, banks possessed a stock of pennies so large that it was completely unnecessary to put any more in general circulation, The Royal Mint said.

So, as part of a convention, 1933 King George V pennies - among others - were instead buried beneath the foundation stones of new buildings.

"There was a convention at the time that complete sets of coins of the current year were buried under the foundation stones of new buildings," The Royal Mint said.

"Consequentially, three 1933 pennies were struck for buildings erected in that year, along with a small number to be kept as record copies by the British Museum and the Royal Mint Museum."

If you're lucky enough to find a 1933 King George V coin, you're essentially sitting on a goldmine.

Chris said that such a coin may sell for a staggering £72,000 - after one was sold at an auction in 2016, MailOnline reports.

It seems the value is only increasing as one was reportedly sold for £40,000 in 2004, and £45,000 in 2006.

"This is one of the rarest British coins because only a few were ever produced as part of a special minting for record-keeping," Chris said.

"The rarity and historical significance of the coin makes it highly sought after by collectors.

"If you find one of these coins, high-end auction houses like Sotheby's or Bonhams would be the best option."

3. 2009 Kew Gardens 50p coin

Last but not least, Chris drew to our attention an unusual 50p issued in 2009 to mark the 250th anniversary of Kew Gardens.

If you've ever visited the gardens, you may recognise the coin's Chinese Pagoda which was originally built in 1762, but freshly restored in 2018.

"Only 210,000 coins were minted, making them one of the most sought-after 50p coins in circulation," Chris said.

"The coin commemorates the 250th anniversary of Kew Gardens, featuring the iconic Pagoda on the reverse of the coin."

Chris believes that eBay and the London Coin Company are two of the best places to sell these coins.

Although they can fetch between £150 and £200, it may depend on their condition.
