1 Fiorino - Ferdinando I

Castiglione delle Stiviere was a tiny Imperial fief in the Gonzaga orbit, granted the right to mint by the Holy Roman Emperor — a privilege jealously exercised by the local lords well beyond what their political weight might suggest. Ferdinando I Gonzaga-Vescovi ruled the principality for over six decades, and the long date range of this emission reflects a sustained minting program rather than a single issue.

The fiorino denomination itself deliberately invoked Florence's gold standard, lending credibility to coinage from a mint that would otherwise have struggled for acceptance in regional trade.
