1 Ducat Siege coinage, countermarked

Danzig held out against Stefan Batory's siege for months in 1577, refusing to recognize his election as King of Poland without guaranteed city privileges. To fund its defense — mercenaries, fortifications, emergency provisions — the city issued its own coinage under municipal authority, a direct assertion of financial independence from a crown it had not yet accepted. The countermark on this piece authenticated it for local circulation during the blockade, distinguishing city-sanctioned gold from foreign ducats that were flooding the market as the siege dragged on.

Batory never took the city by force. Danzig negotiated its terms.
