Talar koronny - Stanisław August Poniatowski Warszawa mint

The 1766 talar was struck under a monetary reform program pushed through the same year Poniatowski established the Commission of the Treasury — Poland's first attempt at systematic fiscal governance after decades of magnate-driven monetary chaos. The reform standardized coinage across the Commonwealth and brought the talar into alignment with the Saxon convention standard, a deliberate signal to neighboring powers that Warsaw could manage its own finances.

Kop. 2456 is among the more frequently encountered varieties of this type, though genuine examples in problem-free silver still require scrutiny — contemporary counterfeits circulated widely, struck in debased alloy by interests hostile to the reform's success.
