20 Litara JNA, Gasoline

The JNA issued fuel coupons — including petrol allotments denominated in litres rather than currency — to manage internal military logistics during Yugoslavia's chronic hard-currency shortages of the 1980s. These were not money in any conventional sense but functioned as scrip within the closed economy of the armed forces, redeemable at military filling stations and depots inaccessible to civilians.

Surviving examples turn up more often than their ephemeral purpose would suggest, largely because Yugoslav conscripts and lower-ranking soldiers sometimes retained them as curiosities rather than submitting unused coupons for cancellation.
