Dukat koronny - Sigismund III Vasa Kraków mint

Sigismund III's ducats from the Kraków mint fall within one of the most politically turbulent stretches of his reign — the years immediately surrounding the Polish intervention in Muscovy, which saw Commonwealth forces occupy the Moscow Kremlin in 1610. War of that scale demanded extraordinary fiscal mobilization, and gold coinage from this window was struck and spent with unusual urgency.

The five Kopicki references spanning this date range reflect distinct annual die variations rather than type changes — Kop#1407 in particular is notably scarcer in surviving examples than its neighbors in the sequence.
