Denier - Louis I

Louis I of Brandenburg — also known as Ludwig the Roman — was the son of Holy Roman Emperor Louis IV, who granted him the Margraviate in 1351 as part of a broader Wittelsbach dynastic consolidation. This denier falls precisely at that transitional moment, when the House of Wittelsbach was tightening its grip on Brandenburg's minting apparatus ahead of the Golden Bull of 1356, which would formally enshrine the Margrave of Brandenburg as one of the seven imperial electors.

Bahrf#580 is a well-documented attribution, though die alignment and minor legend variations within this type are not unusual at this weight class.
