0,20 Dinara Rudstroj, Kakanj

Rudstroj was a construction and mining enterprise operating in Kakanj, a coal-mining town in central Bosnia. This fractional note — twenty paras, one-fifth of a dinar — is a classic example of the emergency scrip that Bosnian state-owned companies issued during the severe Yugoslav dinar liquidity crises of the early 1990s, when small-denomination coinage and banknotes simply vanished from circulation. Enterprises paid workers and ran canteen and company-store transactions on their own paper.

The only security feature is a company seal impression — entirely typical of this genre, where speed of production mattered more than counterfeiting resistance. Kakanj scrip of this type is poorly documented in mainstream catalogs.
