Denier - Henri Ier Ratisbonne

Henri Ier — Heinrich I of Bavaria, nephew of Otto I — held the duchy under constant tension with imperial authority, having been stripped of it once before his restoration in 948. The Ratisbon mint, operating from Regensburg, was among the most active in the eastern Frankish territories during this period, a direct consequence of the city's position as the commercial gateway to the Danube trade routes into Central Europe.

The seven-year window this type was struck closes with Heinrich's death in 955, the same year Otto crushed the Magyars at the Battle of Lechfeld — a victory Heinrich himself fought in.
