1 Öre 'Klippingar' - Gustav II Adolf Arboga mint

Klippingar — the Swedish term for "clipped" or square-cut coins — were emergency copper issues produced when round planchet production couldn't keep pace with demand. Gustav II Adolf's aggressive military campaigns in the Thirty Years' War required enormous logistical funding, and copper coinage was central to Sweden's monetary strategy given the kingdom's vast copper reserves at Falun. The Arboga mint operated intermittently, and these square flans were the expedient answer to a production bottleneck rather than a deliberate aesthetic choice.

The 1626–1627 window at Arboga is notably short; the mint's copper klipping output was largely superseded as infrastructure improved elsewhere.
