20 Kruna

This note was not newly printed — it is a converted Austrian Kronen note, overstamped for use in the newly proclaimed Kingdom after the collapse of Austria-Hungary in 1918. The Yugoslav authorities needed a circulating currency immediately and had neither the time nor the infrastructure to print their own. Stamping existing Austro-Hungarian notes was the practical solution, however imperfect.

The conversion process was politically charged. Stamping was meant to prevent an uncontrolled flood of old imperial currency from destabilizing the new state's finances, but enforcement was uneven across the former empire's fragmented territories.
