King Charles III coins: The new 50p coin is worth up to £200 - where and how to find it

The Royal Mint has unveiled the new 50p coin featuring King Charles III, and it could be worth a small fortune if you find one in your change.

The new coin will enter circulation from December, replacing the old design which featured the late Queen Elizabeth II. It is the first time in 70 years that there has been a new monarch on British coinage.

The new coin features an effigy of King Charles III by Martin Jennings, which was personally approved by the King. The reverse of the coin features a design by John Bergdahl which incorporates the four quarters of the Royal Arms within a shield.

The Royal Mint has said that the new 50p coin will be "widely available" in change, but there are some things you can do to increase your chances of finding one.

• Check your change regularly.
• Ask your bank or building society if they have any new 50p coins.
• Visit the Royal Mint website to buy a commemorative coin.

If you do find a new 50p coin, it is worth checking its value online. Some of the rarest coins can sell for hundreds of pounds.

The most valuable 50p coins are those that have been struck with errors. For example, a 50p coin that was struck with the Queen's head upside down sold for £200 on eBay in 2017.
