Denier - Ferdinand I

Ferdinand I spent much of his Hungarian reign fighting—financially and militarily—against Ottoman encroachment, and these small silver deniers functioned as the workhorse coinage for a kingdom that was effectively partitioned into three competing zones of control. The Habsburgs held a thin strip in the west and north, the Ottomans held the central plains, and Transylvania operated as a semi-independent vassal state. Coinage continuity in Habsburg Hungary was partly a political statement of territorial claim.

The H#936 and H#951 references suggest minor die or mint variations within this date range — Kremnitz being the dominant source, though other Hungarian mint facilities contributed sporadically during this period.
