50 Kroner Great Norwegian Spitsbergen Coal Company

Store Norske Spitsbergen Kulkompani — commonly shortened to SNSK — operated a company town economy at Longyearbyen on Svalbard, where the Norwegian state held a majority stake from 1945 onward. These scrip notes functioned as a parallel currency within the settlement, used at the company store and for internal transactions among miners who had limited access to mainland Norwegian banking infrastructure. The archipelago's unique legal status under the 1920 Svalbard Treaty complicated the use of standard Norwegian krone in everyday settlement commerce.

The 1973 date places this issue well into the Soviet-era rivalry period, when the Soviet mining trust Arktikugol operated its own parallel economy at Barentsburg — each company effectively running a separate monetary microclimate on the same island.
