1 Weißpfennig - Frederick III of Saarwerden

Frederick III of Saarwerden held the archbishopric for nearly four decades, and his coinage reflects the fractious politics of the Rhenish monetary union, to which Cologne was a founding member in 1386. The Weißpfennig — literally "white penny," named for its silver content distinguishing it from billon issues — was the workhorse denomination of Rhine valley commerce during this period, struck in enormous quantities to facilitate trade at the great Rhenish fairs.

Noss Cologne II #215 places this within a well-documented sequence, though die combinations within the type vary considerably across the reign's three-decade span.
