1 Lira - Ferdinando I Gonzaga

Castiglione delle Stiviere was a tiny imperial fief in Lombardy whose Gonzaga branch maintained the right to strike coinage largely as a prestige exercise — the principality's territory was barely large enough to sustain a court, let alone a meaningful monetary economy. Ferdinando I ruled from 1616 until his death in 1678, an unusually long tenure that accounts for the broad date range attributed to this type, though the actual period of active minting was almost certainly far narrower.

CNI IV records only four specimens across references 9–12, suggesting survival is genuinely limited rather than merely understudied.
