Denier - Władysław Opolczyk Wieluń mint

Władysław Opolczyk governed Wieluń as a vassal duke under Louis I of Hungary, who held the Polish crown from 1370 following the death of Casimir the Great. The Wieluń mint operated under this arrangement — a Hungarian-aligned magnate striking local silver in a region that changed administrative hands repeatedly across these decades. Opolczyk was eventually stripped of his Polish territories by Władysław II Jagiełło in 1396, making the mint's operational window tight and its output correspondingly limited.
