The Royal Mint has released a new collectable 50p coin to celebrate the life of British scientist and codebreaker Alan Turing.

Computer genius Turing is best known for breaking the German Enigma code during World War Two, leading to victory over Nazi Germany.

Historians believe he may have shortened the war by four years - saving tens of thousands of lives.

Turing already features on the new polymer £50 note - and now the Royal Mint are honouring him on a coin for the first time.

The 50p is available in gold, silver and base metal and was designed by artists Matt Dent and Christian Davies.

The reverse side of the coin features the name Alan Turing alongside an image of the Bombe machine used during the Second World War.

In a special nod to his work, the designers have incorporated hidden word sequences as part of the 50p design.

Each one represents a Turing quote and significant location, as well as the designers' initials.

The coin is the final release in the Innovation is Science 50p series, which also features Charles Babbage, John Logie Baird, Rosalind Franklin and Stephen Hawking, and the Discovery of Insulin.
