Złotówka koronna - Stanisław August Poniatowski Warszawa mint

These złotówki were struck during the Commonwealth's final, desperate attempt at self-preservation — the period spanning the Constitution of May 3rd, 1791 through the Kościuszko Uprising and the Third Partition of 1795, after which Poland ceased to exist as a sovereign state for 123 years. The Warsaw mint continued striking coinage even as Russian troops occupied the capital, making the later dates in this range effectively emergency issues produced under occupation.

The .550 fineness was itself a compromise — lower than the Commonwealth's earlier silver standards, reflecting chronic treasury shortages that plagued Poniatowski's reign from the outset.
