1 Pfennig - Ferdinand I Klagenfurt

Ferdinand I consolidated the Habsburg hereditary lands in the 1520s following his brother Charles V's division of the dynasty, and Klagenfurt served as the administrative capital of Carinthia throughout his reign. The Klagenfurt mint operated intermittently during this period, producing small billon issues for local circulation in a region where currency fragmentation — different coinage standards across Styria, Carinthia, and Tyrol — remained a practical headache for merchants and tax collectors alike.
