50 Øre Great Norwegian Spitsbergen Coal Company

Store Norske Spitsbergen Kulkompani — commonly abbreviated SNSK — operated the coal mining settlement at Longyearbyen on Svalbard and issued its own scrip currency for use within that closed company town. Workers were paid partly in this local currency, redeemable only at the company store. The arrangement kept money circulating inside the settlement and reduced the logistical burden of importing Norwegian krone in sufficient quantity to a remote Arctic archipelago with no permanent civilian banking infrastructure.

The SN13r designation indicates a remainder — unissued stock, never formally put into circulation. Remainders from this series survive in higher numbers than genuinely circulated examples, which took considerable punishment in a mining camp environment.
