Denier - Louis II and Angelberga

Louis II co-ruled Benevento with his empress Angelberga during a turbulent Italian campaign against the Arab occupation of Bari, a siege that finally succeeded in 871 — the same year this joint issue ceased. The inclusion of Angelberga's name on a coin alongside a Carolingian emperor is genuinely unusual; empresses rarely received such explicit monetary recognition, and scholars have read it as Louis reinforcing dynastic legitimacy at a moment when his grip on southern Italy was anything but secure.

Louis was captured by the Lombard prince Adelchis of Benevento in August 871, held for roughly a month, and released only after swearing an oath not to return. He died the following year.
