Dukat koronny - Stanisław August Poniatowski Warszawa mint

The 1766 crown ducat was struck just two years into Poniatowski's reign, a period when the new king was still navigating the suffocating influence of Catherine the Great, who had effectively installed him on the throne. The Warsaw mint had been dormant for gold coinage for years prior, and its revival for ducat production in the mid-1760s coincided with Poniatowski's broader push to modernize Polish fiscal infrastructure — reforms that Russian and Prussian interests would spend the next decade systematically dismantling.

Kopicki lists two varieties under 2493 and 2494, distinguished by minor die differences. Both are scarce in any grade; gold issues from Warsaw in this decade saw limited production runs and heavy attrition through export and melting.
