1 Kreuzer - Ferdinand III Prague

Ferdinand III inherited the Bohemian crown in circumstances shaped entirely by his father's brutal suppression of the Protestant revolt — the Battle of White Mountain in 1620 had effectively ended Bohemian autonomy, and the Prague mint by the 1630s operated under direct Habsburg fiscal control. The Thirty Years' War was still grinding through its final decade when these kreuzers circulated, and small silver fractions like this saw punishing use as larger denominations were hoarded or melted.

KM#411 encompasses several die varieties across the six-year emission window. The Prague mint's output during this period was inconsistent in quality, a direct consequence of wartime disruptions to silver supply from the Bohemian mining districts.
