Szóstak gdański - Stanisław August Poniatowski Gdańsk mint

Poniatowski was elected king in September 1764 under heavy Russian pressure — Catherine II's ambassador Count Repnin effectively stage-managed the Sejm vote. These Gdańsk szóstaks were struck almost immediately after his accession, when the new king still had enough political room to maintain the city's traditional minting privileges. Gdańsk operated semi-autonomously within the Commonwealth, and its mint consistently produced work of higher technical quality than the royal mints at Warsaw or Kraków.

The Kopicki references split this short issue across at least three die varieties, suggesting active production across both years before the mint's output was curtailed.
