Trojak litewski - Stefan Batory Wilno mint

Stefan Batory's Lithuanian trojaks from the Wilno mint occupy a specific administrative niche: the Grand Duchy of Lithuania maintained its own mint operation distinct from the Polish Crown issues, which is why Wilno-struck trojaks carry separate reference numbers from their Poznań or Olkusz counterparts despite identical face value. Batory had been elected king in 1576 partly through Lithuanian noble support, and sustaining a productive Wilno mint was part of the political currency of that relationship.

The 1585–1586 span corresponds to the final years of Batory's reign; he died in December 1586, leaving both mints mid-production.
