1 Heller 'Adlerheller' - Otto I

Palatinate-Mosbach-Neumarkt was itself a short-lived partition of the Rhenish Palatinate, created in 1443 when Palatinate-Mosbach was divided between two sons of Otto I of Mosbach. The resulting territory governed by Otto I of Neumarkt lasted only until his death in 1461, leaving a narrow window for coin production. The Adlerheller — named for its eagle type — was a fractional denomination already archaic by the mid-fifteenth century, clinging to circulation in the fragmented southwest German principalities long after larger territorial powers had rationalized their coinage.
