In 1940 a man decided to take some precautionary measures to protect his savings against the imminent threat of the Battle of Britain. To avoid being left without means in the event of a German invasion, prevent devaluation of his savings and possibly also to speculate in rising silver prices he bought two large silver ingots, worth £250 and weighing about 90 kilograms, loaded them into a pram, and went out to bury them in a small wood nearby. The man was Alan Turing (1912–1954), famous for his wartime success in breaking the German Enigma code with his team, and for his groundbreaking work on electric machines which were to develop into the first real computers. Turing is also well-known to many who work with coins as one of the scholars behind the Good-Turing frequency estimation formula, used within numismatics to calculate the number of coins of a specific type produced from an identified number of dies. This paper meanders from Alan Turing's hidden treasure on to his scientific work and to his various connections with numismatics: the Good-Turing formula, Joan Clarke, and commemorative coins.
