Pfunder - Ferdinand I Graz

The Pfunder — sometimes called a Pfund or pound-weight piece — was a large-denomination silver coin introduced in the Habsburg territories as trade coinage demanded heavier, more standardized silver. Ferdinand I, then Archduke of Austria and still consolidating his grip on the hereditary lands after the 1526 Bohemian and Hungarian inheritances, used the Graz mint in Styria as one of his primary southern minting centers. The Styrian silver supply from mines in the eastern Alps fed directly into production here.

1533 places this coin squarely within Ferdinand's ongoing financial strain from Ottoman pressure — Suleiman had besieged Vienna in 1529, and the defense costs were immense.
