1 Skilling - Frederik I Oslo

Frederik I inherited a Norwegian mint at Hamar that had been dormant for decades, and his decision to resume coinage in the late 1520s was driven less by economic planning than by an urgent need to assert Danish royal authority over a kingdom still administratively resistant to the union. The Oslo mint — reactivated under his reign — produced these skillings across a narrow window that corresponds closely with the ongoing suppression of Archbishop Olav Engelbrektsson's political opposition, the last serious institutional challenge to Danish control of Norway.

Multiple die varieties account for the Skaare, Brekke, and Schive reference splits — this is not a single uniform issue but a loosely supervised early mint run with meaningful variation between obverse dies.
