1 Ducat - Frederick Charles

Frederick Charles of Schleswig-Holstein-Norburg-Plön ruled one of the smallest and most financially marginal of the Holstein cadet duchies, a patchwork of German territories whose ducal lines were perpetually entangled with Danish royal succession politics. By 1760, the duchy's independent coinage was already an anachronism — the minting of gold ducats at this scale was less about circulation than about asserting dynastic standing in a political environment where that standing was increasingly precarious. Frederick Charles died in 1779 without male heirs, and the Plön line was extinguished shortly after.
