6 Dinara Samoupravna interesna zajednica za ceste Hrvatske

Samoupravne interesne zajednice — self-managing interest communities — were a peculiar institutional invention of Titoist Yugoslavia's 1974 constitution, which fragmented public services into semi-autonomous bodies funded through earmarked contributions rather than central budgets. Croatia's road community issued these low-denomination coupons as a mechanism for collecting road maintenance fees, effectively functioning as a parallel scrip rather than legal tender in the conventional sense.

The Yugoslav experiment with such quasi-fiscal instruments was largely abandoned by the early 1980s as the federation's economic contradictions deepened. These coupons survive in collector hands almost entirely uncirculated — their utility was administrative, not transactional.
