2 Groats 'Vierlander' - Charles the Bold

Charles the Bold inherited Flanders from his father Philip the Good in 1467 and almost immediately restructured the coinage of the Burgundian Netherlands through the monetary ordinance of 1468, which mandated a unified billon standard across his territories. The Vierlander — so named because it circulated across four lands simultaneously — was a direct product of that administrative push toward monetary integration in the Low Countries.

The .479 fineness reflects a deliberate compromise, low enough to conserve silver while maintaining credibility against competing regional issues flooding Flemish markets.
