1 Fyrk - Gustav II Adolf Arboga mint

Gustav II Adolf's copper coinage of the 1620s was a direct consequence of Sweden's deliberate policy of monetizing its domestic copper surplus — the country controlled some of the most productive copper mines in Europe, centered on Falun, and flooding the economy with small copper coins was a calculated move to manage metal reserves while financing the king's ongoing military campaigns in the Baltic and Poland. The Arboga mint was one of several provincial facilities activated during this period to meet demand that Stockholm alone could not satisfy.

Arboga's output is distinguished from other mint towns by its specific mintmaster marks, worth confirming against the die details when attributing this type.
