Picciolo

The picciolo was Florence's small-change answer to a practical problem: the florin, by the early fourteenth century, had become so valuable that it was useless for everyday market transactions. The Republic issued billon piccoli as the workhorse of street-level commerce — bread, wine, ferry crossings. The specific window of 1315–1331 spans a period of considerable factional turbulence in the city, including the brief lordship of Robert of Naples, whose influence over Florentine affairs forced repeated constitutional renegotiations without disrupting the mint's output in any documented way.

MIR 80 is among the more frequently encountered picciolo types, suggesting sustained production across the full dating range.
