Do you have a rare 50p piece rattling around in your pocket? The Royal Mint has revealed its rarest 50 pence coins in circulation - including one that sells for more than £600.
The Royal Mint is the government-owned mint that produces all the coins for the United Kingdom - as well as developing currency for more than 60 countries around the world.
It says that decimalisation of currency in the UK in February 1971 inspired thousands of people to become coin collectors - and over the years, the 50 pence has grown to become Britain’s most collectable coin.
