In the build-up to the London 2012 Olympics, the Royal Mint held a coin-design competition to produce a series of 50p pieces on an Olympic sports theme. The competition was open to anyone, and it resulted in 29 coins and introduced the youngest-ever designer of United Kingdom coinage at just nine years old.

With the highest mintage being the archery coin by Piotr Powaga at 3,345,500 and the lowest mintage being the wrestling coin by Roderick Enriquez at 1,129,500, any of these Olympic coins are a rare and exciting addition to a collection.

Top off your finished 2012 Olympic 50p coin collection with this Olympic completer medallion to celebrate your hard work in assembling all 29 pieces.
