The Royal Mint has revealed the rarest 50p coins in circulation, ahead of the 50th anniversary of decimalisation.
The famous Kew Gardens 50p remains the most coveted coin in circulation, with a mintage of just 210,000, the Royal Mint said. Other rare designs include Olympic-themed 50ps minted in 2011.
In 2019 more than 500 million coins were released into circulation, including three new 50p designs celebrating Arthur Conon Doyle's fictional detective Sherlock Holmes, and Paddington Bear at St Paul's Cathedral and the Tower of London.
The 50th anniversary of decimalisation is on February 15, with the changeover having inspired many people to become coin collectors over the years.

The Royal Mint's director of UK currency Mark Loveridge said: "Coin collecting remains as popular as ever, and we were delighted to release a number of special designs into circulation in 2019.
"The Kew Gardens 50p remains the most coveted coin, with a mintage of just 210,000, but it's always exciting to find a special design in your change."
