Historical Context

Period: Early 18th century, during the reign of Frederick I of Sweden (1718–1751).
Political backdrop: Sweden had just emerged from the Great Northern War (1700–1721), which ended Swedish dominance in the Baltic region. The country was economically strained, and copper coinage became essential because silver was scarce.
Monetary system: Sweden used a copper-based currency system for small denominations, as copper was abundant domestically. Large copper plate money was also in circulation.
1720 significance: This year marked the beginning of the Age of Liberty in Sweden, a parliamentary era after the death of Charles XII. Coinage reflected stability efforts in a recovering economy.
