1/4 Thaler - Ferdinand I Klagenfurt

Ferdinand I consolidated Habsburg control over the Austrian hereditary lands while simultaneously managing the Ottoman threat following Suleiman's campaigns into Hungary and the siege of Vienna in 1529. The Klagenfurt mint, serving Carinthia, operated under direct imperial authorization during this period as Ferdinand standardized coinage across his territories — a practical necessity when financing both administration and military commitments on multiple fronts simultaneously.

Markl 1463 and 1464 represent distinct die variations for this type, a detail worth noting when attributing examples precisely.
