The coin includes several hidden codes as seen below:
Code 1: The 3 words ‘GEARS GRIN THAN’ when entered into What 3 Words (https://what3words.com/gears.grin.than) take you to Cambridge University, where Alan Turing Studied Mathematics.
Code 2: ONLY A FORETASTE OF WHAT’S TO COME - This quote came from his reflections of his code-breaking machine, Bombe.
Code 3: CD AND MD, the designers initials.

Interesting fact
One interesting fact about the Alan Turing 50p coin is that it features a unique design that commemorates the life and work of Alan Turing, a British mathematician, computer scientist, and codebreaker who played a crucial role in cracking the German Enigma code during World War II. The coin's design includes a depiction of Turing's face, as well as a representation of the Enigma machine and a pattern of 1s and 0s in binary code, symbolizing Turing's contributions to computer science and cryptography.
