The Royal Mint has launched a competition inviting people to design a special commemorative coin for the London 2012 Olympics.

The competition is open to the general public and offers a winner the chance to have their designs made into coins and circulated, as well as a £1,000 cash sum. Contestants must select one of 27 Olympic and Paralympic sports to represent on their design; they may not include the image of recognizable sportsmen or sportswomen, and they must include the Olympic or Paralympic logo.

Would-be coin designers have until April 24 to register their interest in competing through the Royal Mint's website; they will then receive a template and detailed guidelines.
