The Royal Mint are asking the public to design one of 27 coins to represent sports from Archery through to Wrestling. Designs however, must not include a recognisable likeness of a known sportsman or sportswoman. There are some more rules and you must follow the template given as some elements remain static like the London 2012, London Olympic Games Logo. So if you want to design a coin for the 30th Olympiad head on over to royalmintcompetition.co.uk
