Interesting fact
One interesting fact about this coin is that it features a unique design depicting Alan Turing, a British mathematician, computer scientist, and codebreaker who made significant contributions to the development of computer science and artificial intelligence. The coin was issued to commemorate the 100th anniversary of Turing's birth and includes a representation of the Turing Machine, a theoretical model for computation that Turing first described in his 1936 paper "On Computable Numbers." The coin's design also includes a pattern of 1s and 0s, symbolizing binary code and reflecting Turing's work on the development of computer programming.
