Trojak / 3 Grosze - Sigismund III Vasa Wilno mint

The Wilno mint — operating under lease arrangements common to Commonwealth monetary administration — produced trojaki in considerable volume during the early 1600s, yet the 1601 Wilno issues are among the more vexing for attribution specialists. Sigismund III's reign saw persistent debasement pressure on the grosze denominations, driven partly by Swedish war expenses and partly by the flood of inferior imitations entering from Silesia and Riga that the Sejm repeatedly failed to suppress.

The Ig#V.01 reference places this among Ivanauskas's tightly sequenced Wilno die classifications for the year.
