5 Leva Kremikovski Metal

Issued to commemorate the Kremikovtsi metallurgical complex outside Sofia, this coin belongs to a wave of Bulgarian commemoratives celebrating socialist industrial achievements during the late Zhivkov period. The Kremikovtsi plant, built in the 1960s with Soviet technical assistance, was one of the largest steel works in the Balkans — and also one of the most environmentally ruinous, a fact the regime was not advertising in 1988.
