Ternar / Trzeciak gdański - Sigismund III Vasa Gdańsk mint

The Gdańsk trzeciak — a three-grosz piece struck for Poland's most commercially active port city — reflects the mint's semi-autonomous status under Sigismund III, who spent much of his reign fighting Swedish dynastic claims to a throne he believed was rightfully his. Gdańsk retained minting privileges partly as a concession to its powerful merchant class, whose tax revenues and naval access the Crown could not afford to alienate. The Kopicki references spanning this short run suggest at least three catalogued die variants across the four-year production window.
