Warm meal coupon - higher value SOUR RMK Zenica, RO Metalno, OOUR Rudarska oprema, Zenica

SOUR RMK Zenica was the integrated steel and mining combine that dominated industrial life in Zenica, Bosnia, through the Yugoslav socialist period. This coupon was issued by the OOUR Rudarska oprema — the mining equipment production unit within the RO Metalno subdivision — as part of the internal social welfare system that Yugoslav enterprises were legally required to maintain for their workers. Warm meal subsidies were administered at the OOUR level, meaning individual production units ran their own coupon systems rather than the combine issuing a single unified series.

The "higher value" designation implies a parallel lower-denomination coupon existed within the same issue, likely distinguishing between meal types or canteen pricing tiers.
