A Royal Mint 50p coin, valued at between £5,000 and £6,000, is set to go under the hammer at auction.

The gold proof Kew Gardens 50p is one of a number of sought-after coins being sold by the Royal Mint.

As well as the 50p, collectors will have the opportunity to bid on a Queen’s Beast one kilo gold coin, which could fetch as much as £90,000.

The Kew Gardens 50p is a highly desirable coin, due to its scarcity in circulation and as a commemorative coin. The coin features a design celebrating the botanical garden, depicting the pagoda at Kew with a decorative leafy climber twining in and around the tower. A total of 629 Kew Garden gold proof 50p coins were minted in 2009.

The Queen’s Beasts coin pays homage to Queen Elizabeth II and features the 10 beasts side-by-side in a single design.

The design takes its inspiration from the 10 stone statues which lined the late Queen’s route to Westminster Abbey at her Coronation in 1953.

Only 16 of these coins were created by the Royal Mint and the one being auctioned is estimated to sell for in the region of £80,000 to £90,000.

With over 300 lots up for sale, each coin as part of the Royal Mint’s latest auction has been authenticated and valuated by the Mint’s team of numismatic experts.

Bidding will be available until December 3 and collectors can submit their bid by visiting the Royal Mint’s website.

Lucy Mackenzie, director of collector services said: “Over recent years the Royal Mint has successfully expanded into auctions, offering rare and coveted coins which have been sourced by our team of experts.

“This month we will host our largest auction to date, offering collectors around the world the chance to own a piece of British history, authenticated by the original maker of UK coins.”

What makes a coin valuable?

The 50 pence piece has become the most valued and collected coin in the UK, with many collectable designs appearing on its heptagonal canvas.

Its 27.5mm diameter makes it the largest of any British coin, and allows space for decorative pictures. It has often been used to celebrate big events over the past 50 years of British history.

The rarest coins tend to be of the greatest value, with the mintage (number of coins with each design made) being the fundamental attraction for collectors.

Along with the design, other aspects of the coin which increase value are the condition of the coin and whether it has an error in its design.

The way in which it is sold can also determine the coin’s value - while some coin collectors will bid vast amounts of money on eBay or at auction, others opt for more robust valuations by selling via a coin dealer.


Rarest 50p coins in circulation the UK?

The rarest is the Kew’s Garden 50p, which was designed to mark the 250th anniversary of the gardens in 2009. Only 210,000 coins were ever minted with this design.

The Kew Gardens 50p sells for £156.25 on average, but one seller received over £700 for one when they sold it on eBay.

The other rarest coins stem predominantly from the 2011 Olympics, with the wrestling, football and judo coins among the most valuable. Only 1.1million of each of these coins were produced.

Flopsy bunny and Peter Rabbit designs which were produced in 2018 are also highly valuable.

These coins - 1.4 million of which were minted - depict the characters from Beatrix Potter’s novels and celebrate the life of the English writer and these sell for around £5.

In 2019, 500 million coins were produced, with three new 50p designs.

These included one of Arthur Conan Doyle’s Sherlock Holmes, Paddington Bear at St Paul's Cathedral and the Tower of London.
