North Korea's aluminum coinage of the 1980s was produced in two parallel streams: one for domestic circulation, one for foreign visitors and hard-currency transactions through the state's official exchange network. KM#18 belongs to the domestic series, distinguishable from the tourist issues by the absence of a star or other differentiating mark used to segregate currency flows — a system the DPRK maintained to prevent convertible foreign exchange from bleeding into the general economy.
