1/2 Thaler - Ferdinand I Klagenfurt

Ferdinand I acquired Carinthia as part of the Habsburg partition of 1521, when Charles V ceded the Austrian hereditary lands to his younger brother. Klagenfurt became the ducal capital only in 1518, three years before Ferdinand's rule began, having been purchased from the Estates — making this issue among the earliest struck there under Habsburg authority.

Markl 1462 places this within a well-documented but scarce series. The forty-three year reign span means dies and mintmasters changed repeatedly, and attributing specific strikes to narrow date ranges within that window remains genuinely difficult.
