20 000 Dinara University campus Dobrica Stambolić, Niš

Studentski dom "Dobrica Stambolić" was a student dormitory in Niš, and this 20,000 Dinara note is a canteen or meal voucher issued by the institution itself — not legal tender in any sense, but a product of Yugoslavia's chaotic late-1980s hyperinflation. By 1989, the dinar was losing value so rapidly that institutional scrip of this kind became a practical necessity: dormitory administrations issued their own internal currency to insulate student meal programs from daily price fluctuations.

Dobrica Stambolić was a Serbian communist official; the dormitory bearing his name would have been renamed sometime after 1990.
