10 000 000 000 Dinara

The Republic of Serbian Krajina was a self-declared Serb breakaway state within Croatia, never internationally recognized and ultimately dissolved when Croatian forces retook the territory in Operation Storm in August 1995. By 1993, hyperinflation was already consuming the rSK's monetary system in lockstep with the catastrophic inflation gripping the Federal Republic of Yugoslavia — the Krajina dinar was effectively a satellite currency, pegged to nothing and printed in Belgrade at the ZIN facility that simultaneously supplied the FRY's own disintegrating denominations.

A ten-billion-dinar face value issued in the same year Yugoslavia briefly recorded the highest inflation rate in recorded history. The watermark is the sole security feature.
