50 000 000 000 Mark Württembergische Notenbank

The Württembergische Notenbank was one of four private German note-issuing banks — alongside the Bayerische Notenbank, the Sächsische Bank, and the Badische Bank — that retained limited issuing rights alongside the Reichsbank into the Weimar period. By the time this 50-billion-Mark denomination was authorized, inflation had progressed to the point where such figures represented ordinary transactional amounts, not exceptional emergency values.

Stähle & Friedel were a Stuttgart commercial printing firm pressed into currency work by necessity, not specialization. Franz Kaufmann's involvement as designer suggests a deliberate attempt at visual coherence even at the height of monetary collapse — the Notenbank maintained institutional appearances while the numbers became surreal.

The series was rendered void by the Rentenmark stabilization of late November 1923.
