1/2 Thaler / 36 Kreuzers - Ferdinand I Klagenfurt

Ferdinand I had ruled the Austrian hereditary lands since 1521 but didn't become Holy Roman Emperor until 1558 — meaning this Klagenfurt half-thaler was struck in the first full year of his imperial title. Carinthian coinage of this period falls under the broader monetary reorganization that followed the Reichsmünzordnung of 1559, which attempted to standardize thaler-based denominations across the Habsburg territories.

Markl 1533 is among the scarcer Klagenfurt issues of Ferdinand's reign. The mint there operated intermittently, and surviving half-thalers from this specific year are infrequently encountered in the trade.
