Described as ‘some of the most beautiful coins ever made’ the Milanese Testone by the goldsmith and medallist Caradosso portray on one side Giovavanni Galeazzo as ‘a youth of ravishing beauty’ and, on the other, Ludovico ‘the archetypal wicked uncle.’ As Porteous observed, ‘the conjunction of the two on either side of the same piece in the years 1481-94 is dramatic.’
