The Testone was introduced in 1474 in Milan and by the end of the century the denomination was established in most of Italy. Inspired by the progress in medallic art under the likes of Pisanello the great Italian families of the Renaissance introduced realistic portraiture to the coinage. Here we have a splendid effigy of Ercole I d'Este combined with the great equestrian statue of Francesco Sforza. This was modelled after Leonardo da Vinci's statue at the Sforza Castello in Milan.
