200 Marks SOUR Nama TRO Robni magazin, Zagreb

Yugoslav workplace vouchers of this type emerged from the self-management economic system, under which large socialist enterprises operated as quasi-autonomous units called SOURs — Složene Organizacije Udruženog Rada, or Complex Organizations of Associated Labour. NAMA was Zagreb's dominant retail chain, and its TRO subdivision issued internal purchasing vouchers used by workers in lieu of or alongside regular wages, redeemable at company stores. By 1987, with inflation accelerating sharply toward the hyperinflationary collapse that would follow within two years, such instruments had a practical half-life measured in weeks.

The 200-mark denomination is notable — pegged notionally to the Deutsche Mark, not the dinar, reflecting how thoroughly ordinary Yugoslavs had stopped trusting their own currency by the late 1980s.
