Groschen - Albert I and Charles I

Münsterberg-Oels passed through a tangle of Piast inheritance disputes before landing jointly under Albert I and Charles I, whose co-rule reflected the Silesian habit of partible succession that fractured ducal authority across dozens of competing lines. Joint coinages of this kind were a political necessity as much as a fiscal one — the shared type asserted parity between brothers who might otherwise have had reason to contest it.

The decade-long span of this issue suggests steady if modest output from a minor mint operating well within the Bohemian Crown's monetary orbit.
