1 Poltura - Leopold I

The poltura — a small-denomination silver struck for Hungarian circulation — proliferated under Leopold I during a period of near-continuous military and political crisis. The kingdom was simultaneously fighting Ottoman forces in the south and suppressing the Thököly-led kuruc uprising in the east, leaving the imperial treasury perpetually strained. These pressures pushed mint output toward lightweight, high-volume coinage, and quality control across the Kremnitz, Nagybánya, and Pozsony facilities was inconsistent enough that multiple KM numbers are required to distinguish the resulting varieties.
