1⁄12 thaler - Charles-Edzard

Charles-Edzard was the last ruling Count of East Frisia, and his death in 1744 without an heir extinguished the Cirksena dynasty entirely — triggering immediate Prussian annexation under Frederick the Great, who had secured succession rights years earlier. Coins struck after 1744 under his name were issued by the Prussian administration during the transition period, giving this series an unusually ambiguous issuing authority for its final years.
