Quadrans - Leopold V

Leopold V governed Tyrol as a separate Habsburg appanage following the 1619 partition that divided the dynasty's Austrian lands among Ferdinand II's brothers. His administration pushed hard to maintain independent coinage rights against centralizing pressure from Vienna, and the quadrans — the smallest practical denomination — was essential for everyday market transactions in the Alpine passes where Tyrolean trade concentrated. The KM# 600.1 variety is distinguished from 600.2 by mintmaster differences traceable to the Hall mint.
