Conrad Otto held Bohemia as a margrave under imperial authority before seizing the duchy outright in 1182, a political maneuver backed by Emperor Frederick Barbarossa that effectively split Moravia from Bohemian ducal control. The coinage issued under his name reflects this contested legitimacy — deniers of this period were struck with minimal central oversight, and die-cutting quality varies sharply across the series. Cach 639 sits in a portion of the catalog where attribution depends heavily on monogram interpretation, and misattributions between Conrad Otto and earlier Přemyslid issues remain a persistent problem in the literature.
