1 Pezza Della Rosa - Cosimo III

The Pezza della Rosa takes its name from the rose design that appeared on the coin — unusual enough that it became the popular identifier rather than any denomination label. Cosimo III's reign (1670–1723) was fiscally turbulent; Tuscany's economy was in slow decline under Medici mismanagement, and large silver issues like this one were struck partly to satisfy trade obligations rather than domestic circulation needs. The grand duchy's mints were increasingly reliant on foreign silver supplies as Medici commercial power contracted across the Mediterranean.

MIR 66 encompasses multiple die marriages across the thirty-year span of this type, and attribution to specific emission years without documentary evidence is rarely straightforward.
