Wismar had been under Swedish administration since 1648, and by 1715 the city was under significant military and financial strain during the Great Northern War. This piece belongs to a class of necessity coinages struck from cannon metal — bronze salvaged or repurposed from artillery — a practice that signals acute shortage of conventional minting stock. At 698 grams, it is a substantial emergency issue, not a routine denomination.
Sweden formally pawned Wismar to the Duke of Mecklenburg-Schwerin in 1803, never to reclaim it. The 1715 date places this coin squarely in the period of Swedish desperation preceding that eventual loss.
