Watch List notes:

Giovanni Antonio de' Rossi, Pope Pius IV (1559-65), uniface lead medal, regnal year 1 (1559-60), bust left wearing cope, the border of which is embroidered with a reclining figure of St John the Evangelist, and a medallion with bust of Christ, 72mm (cf. Arm. II, 216, 15; Pollard 424 = Kress 370a), pierced, some edge damage, very fine contemporary cast. Although unsigned, the medal bears similarities to signed medals by Rossi of Marcellus II (1555) and Paul IV (1556) – see Attwood p. 130-131. Rossi was employed in Florence in 1556, returning to Rome in 1559, the time this medal was created, when he took up a position at the papal mint.
Estimate: 300-400 GBP
