The rarest - and therefore now most collectable - coins to have been produced during the Queen’s reign have been revealed by the Royal Mint.

As Britain continues to change items like stamps and money to carry the profile of new monarch King Charles, experts have been collating which of the coins released during the late Queen's reign are potentially the most valuable.

Among the coins to look out for are a Kew Gardens 50p piece and a selection of special alphabet 10ps from 2018 and 2019. Scroll down for the full list.

Last year the final coins bearing Queen Elizabeth’s profile were struck and the country is now entering a new era for British coinage, says The Royal Mint, as the first coins featuring her son and heir begin to circulate.

While Queen Elizabeth II appeared on more UK coins than any other British monarch - with approximately 27 billion coins still in active circulation – some remain more collectable than others often depending on then numbers of each produced at the time or the occasion for which they were produced for.

The nation’s most collectible coin is the 50p – with its shape lending itself well to commemorative work - and over 100 different designs have appeared on the 50p piece since its introduction.

These include special designs for the Platinum Jubilee, the London 2012 Olympics, and a series of characters from Beatrix Potter’s classic tales.

Mark Loveridge, Director of UK Currency at The Royal Mint said: “2022 marked one of the biggest changes in coinage since decimalisation as we moved from the reign of Queen Elizabeth II to King Charles III.

“The coinage of Queen Elizabeth II spanned 70 years and special designs issued into circulation celebrated some of the biggest events in history. Although the 2022 mintage figures mark the last time that Queen Elizabeth II’s portrait will appear on new coins, over 27 billion of her coins will remain in circulation.

“Coin collecting remains a popular hobby in the UK and the coins of Queen Elizabeth II’s reign are particularly coveted. By sharing the list of rare designs we hope people will look closely at their coins - if they’re lucky they might find a piece of history.”
