25 Doppie

The 25 Doppie was among the largest gold coins struck in early modern Europe, produced by Genoa's mint during a period when the republic's financial networks — not its military power — made it a dominant force in European statecraft. Genoese bankers, operating through the Piacenza fairs, effectively served as the primary creditors of the Spanish Crown for much of the seventeenth century, and prestige pieces of this magnitude functioned as instruments of that financial diplomacy rather than as circulating money.

Surviving examples in any condition are genuinely rare. A 175-gram gold piece at .986 fineness was never intended for a merchant's purse.
