1 Giulio - Clement VII

Clement VII's pontificate produced this issue under conditions of extraordinary political stress — his reign encompassed the 1527 Sack of Rome, during which Imperial and Spanish troops looted the city for eight days, effectively ending the Renaissance papacy's unchallenged temporal authority. Mint operations in Rome were severely disrupted during and after the sack, which accounts for the notable variation in strike quality and die workmanship seen across surviving examples of this type.
