Meal coupon DP Rudnik mrkog uglja, Zenica

DP Rudnik mrkog uglja u Zenici — the Zenica brown coal mine enterprise — issued meal coupons as part of the broader Yugoslav system of worker benefits administered directly by self-managed enterprises (radne organizacije). These were not currency substitutes in any monetary sense but internal scrip redeemable only at the mine's own canteen facilities. The Zenica mining complex was among Bosnia's most significant industrial employers, and this kind of non-cash provisioning was standard practice across heavy industry in socialist Yugoslavia, particularly during tighter supply periods in the 1970s and 1980s.
