1 Giulio - Guido Ascanio Sforza Sede Vacante

Guido Ascanio Sforza served as papal legate governing Ancona and held the title of Cardinal Camerlengo — the office responsible for administering the Church's temporal affairs during a vacancy of the Holy See. The year 1555 saw two conclaves: Marcellus II died after just 22 days, and the sede vacante issues struck under Sforza's authority therefore span an unusually compressed and turbulent stretch of papal succession.

As Camerlengo, Sforza held the explicit right to authorize coinage during interregna. This giulio is one of the more localized expressions of that authority, struck at Ancona rather than Rome.
