Pfennig - Johann II Senn von Münsingen

Johann II Senn von Münsingen held the see of Basel from 1335 to 1365, a tenure marked by the catastrophic Black Death of 1347–1351, which decimated the Rhine valley population and severely disrupted regional trade networks. Coinage from the Bishopric during this period reflects the monetary instability common to mid-14th-century German ecclesiastical mints — silver content was quietly debased as bullion supplies tightened and episcopal finances strained under plague conditions.

The Senn von Münsingen family were Bernese ministeriales, and Johann's elevation to Basel was itself a product of Habsburgian ecclesiastical politics in the western Swiss territories.
