8 Albus

Cologne struck this issue during the Thirty Years' War, when the city's status as a Free Imperial City made it a rare island of relative stability amid the destruction consuming the Rhineland. Municipal coinages proliferated in this period as imperial monetary authority fragmented and regional mints scrambled to meet local demand with their own silver.

The albus — a low-denomination silver coin deeply rooted in Rhenish monetary tradition since the 14th century — remained the practical currency of everyday commerce in the region long after larger imperial denominations dominated official accounting.
