1 Grossone

Pisa struck this grossone during the city's final years of independence, sandwiched between the collapse of Medici control over Florence in 1494 and the city's eventual reconquest by Florence in 1509. The Pisans had seized the opportunity of Charles VIII's Italian invasion to revolt and reassert their autonomy after nearly a century under Florentine dominance — this coin is a product of that brief, desperate window of self-governance.

The MIR 430 attribution places it firmly within the civic coinage series produced under the revived republic, which struggled constantly with siege, famine, and mercenary costs throughout the emission period.
