Three rare British coins that could be worth 'up to £72,900'

Ever tossed aside loose change without thinking twice? One expert's advice may make you wish you hadn't. Incredibly, he's drawn attention to three rare British coins that could be worth 'up to £72,900'.

Three rare British coins could be worth 'up to £72,900' to eagle-eyed collectors, according to an expert.

Incredibly, some spare change knocking around your home could fetch a small fortune - if you know what to look out for.

Coin expert Chris Yang, co-founder of Coins Value, has drawn attention to three coins that could be valuable.

The first is a rare 2p coin that's particularly valuable due to one glaring error.

Issued in 1983, it's unclear how many are currently in circulation, but some suggest they were often part of souvenir sets.

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

"This mistake makes it quite valuable among collectors and it's not uncommon to see them being sold on numismatic auction houses or online marketplaces like eBay."

At present, Chris estimates that a 1983 New Pence can fetch between £500 and £700.

While this may seem like a substantial amount, it's nothing compared to the value of a penny with a fascinating history.

In the 1930s, banks had such a large stock of pennies that it was unnecessary to put any more into general circulation, according to The Royal Mint.

As a result, 1933 King George V pennies, among others, were buried beneath the foundation stones of new buildings as part of a tradition.

"[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 explains.

"Consequently, 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 penny, you could be in for a windfall.

Coin expert Chris Yang has suggested that such a coin might fetch up to £72,000, after one was sold at an auction in 2016, according to MailOnline.

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

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

"The rarity and historical significance of the coin makes it highly sought after by collectors. High-end auction houses like Sotheby's or Bonhams would be the best option [to sell] such a rare coin."

Lastly, Chris highlighted an unusual 50p piece released 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."

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

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