20 Mark - Charles I

Charles I of Württemberg was among the more reluctant participants in Bismarck's German unification project, yet the new Reich's monetary reform of 1871–73 forced his kingdom — like all member states — to abandon its old currency system and strike gold coins to a unified standard. These Württemberg 20 Mark pieces were produced across only three years before the series was effectively supplanted by the consolidated imperial coinage, making the window of production unusually narrow.

Charles died in 1891 having outlived the coin type by well over a decade.
