10 000 000 000 Dinara

The Republika Srpska, the Bosnian Serb entity formed amid the dissolution of Yugoslavia and the wars that followed, issued its own currency series as hyperinflation consumed the broader Yugoslav monetary system in 1993. That year saw some of the most extreme denomination escalation in European monetary history — the Yugoslav dinar itself reached a 5×10²² dinar note before the currency was abandoned entirely. The Republika Srpska series tracked that collapse closely, with denominations climbing through successive orders of magnitude within months.

ZIN in Belgrade printed the notes, placing this firmly within the Serbian state printing infrastructure despite the issuer being a separate political entity across the Drina.
