50 Litara diesel fuel coupon

Yugoslavia operated a rationed fuel coupon system during the energy crises of the 1970s and into the 1980s, when the country's hard currency shortages made petroleum imports increasingly difficult to sustain. These coupons were issued through state distribution channels and had to be surrendered at petrol stations alongside payment — possession alone did not guarantee a fill.

Collectors frequently encounter these alongside banknotes, but they are notaphilic adjacents at best: issued by a federal administrative body rather than a monetary authority, with no fixed-denomination exchange value.
