5 German Marks PBT DD Travnik

Privredna Banka Travnik was one of several small regional joint-stock banks in Bosnia-Hercegovina that issued emergency low-denomination notes — Notgeld in function if not always in name — during the economic disruptions of the early 1920s. The Travnik series circulated locally as fractional currency when coin shortages made small transactions impractical, a problem endemic across the former Habsburg territories following the collapse of the Austro-Hungarian krone system.

The denomination in German marks rather than dinars is the key detail here: it places this note in the brief window when multiple currencies circulated simultaneously in the region before Yugoslav monetary consolidation took firm hold.
