1 Pfennig - Ferdinand I Linz

Ferdinand I struck these small billon pieces from the Linz mint during a period when his Austrian lands were under near-constant financial strain from Ottoman pressure on the eastern frontier — the same decades that saw Suleiman the Magnificent twice threaten Vienna itself. Coin production at Linz served regional circulation needs when larger mints were prioritized for war financing.

The Markl and Schulten references cite at least two distinct varieties within this type, suggesting die production was not tightly controlled across the issue's three-decade span.
