1/2 Öre 'Klippingar' - Gustav II Adolf Säter or Nyköping mint

Klippingar — square-cut emergency coins — were a Swedish expedient born of chronic copper flan shortages and the logistical strain of financing Gustav II Adolf's near-continuous military campaigns across the Baltic. The Säter and Nyköping mints both struck this type in 1625, and attribution between the two remains difficult without clear mint marks, which are often weak or absent on copper klippingar of this period.

Sweden's shift toward copper coinage at scale was driven by deliberate monetary policy: copper was abundant domestically, and the Crown controlled the Falun mine.
