10 Litara diesel fuel coupon

Yugoslavia's hyperinflation of 1992–93 was among the worst in recorded history, peaking at a monthly rate exceeding two million percent by January 1994. Fuel rationing ran parallel to the monetary collapse — the dinar was effectively worthless, so the state issued commodity coupons that functioned as a more stable unit of exchange. These diesel coupons circulated as a de facto currency in ways their issuers had not entirely anticipated.

Printed on unadorned paper with minimal security features, they were relatively easy to counterfeit, and forgeries were widespread by late 1993.
