1 Örtug Visby, type 8

Visby's autonomous minting rights, exercised through much of the 14th century, reflect the town's position as the dominant Hanseatic entrepôt in the Baltic — but by the early 1350s that dominance was already eroding. The Black Death had reached Gotland by 1350, and the disruption to trade networks almost certainly accounts for the compressed issue window of this type. Billon at .450 fineness places this well below the quality of contemporary Lübeck coinage, suggesting either metal supply constraints or deliberate debasement as civic revenues contracted.
