Trojak / 3 Grosze - Sigismund III Vasa Wilno mint

Sigismund III Vasa's trojak issues from Wilno (Vilnius) in these years were produced under the authority of the Lithuanian mint, which operated semi-independently from the Crown mints at Kraków and Poznań. The early 1600s were a period of chronic monetary disorder in the Commonwealth, with debased imitations flooding in from Silesia and the Baltic cities — a problem the Sejm repeatedly failed to legislate away. Wilno-struck trojaki from this run show measurable variation across the three years, and the Iger references distinguish them by die alignment and crown type details rather than any single dramatic change.
