The Sachsenpfennig ("Saxon pfennig"), sometimes called the Wendenpfennig or the Hochrandpfennig ("high rim pfennig"),[1] was a well-known coin of the pfennig type minted in the eastern part of the Stem Duchy of Saxony during the 10th and 11th centuries. It had an upturned perimeter and, next to the Otto Adelheid Pfennig was the most common pfennig type of its time.[2] Sachsenpfennigs are the oldest coins minted in Saxony. Its different names represent a lack of clarity within mediaeval numismatics about the coin.
