Denier - Louis I of Hungary Kraków mint

Louis I of Hungary assumed the Polish throne in 1370 following the death of Casimir III, the last Piast king, who died without a male heir. Hungarian rule over Poland was never popular, and Louis spent little time in Kraków, governing largely through regents — first his mother Elizabeth of Bosnia, then his daughter Jadwiga's eventual succession arrangements. The Kraków mint continued operating under his name, but output was thin and administration inconsistent, which explains the scarcity of well-documented die combinations from this period.

The Kop#345x reference designation with the "x" suffix signals an unlisted or uncertain variety in Kopicki's corpus — a telling detail for a reign whose Polish coinage has never been fully systematized.
