The Royal Mint has revealed its 10 rarest 50p coins - do you have one in your spare change?

As the UK’s decimalisation anniversary approaches, The Royal Mint has revealed its top 10 rarest 50 pence coins, and how much they could be worth.

The UK moved to ‘new money’ pounds and pence, from ‘old money’ shillings and pence, almost 50 years ago, with the anniversary approaching on 15 February 2021.

Since then, over 70 variations of the 50p coin have been circulating and several rare designs have been distributed.

Here, we look at the rarest 50p coins and how many of each have been made - could the spare change in your purse be worth more than you thought?

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.

What are the rarest 50p coins in circulation?

The Royal Mint has revealed the most valuable 50p coin, ahead of the 1971 decimalisation’s golden anniversary.

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.
