Pfennig - unknown ruler Friesach

The Friesach pfennig was one of the most widely imitated coin types in medieval Central Europe — the original Friesacher pfennigs, struck from the late 12th century onward, circulated so extensively across the eastern Alpine regions and into the Balkans that dozens of ecclesiastical and secular mints began producing unauthorized copies. By the early 14th century, distinguishing legitimate Salzburg issues from imitations had become genuinely difficult, which is precisely why so many examples from this period carry unattributable rulers.
