1⁄12 Thaler - Frederick Botho and Charles Louis with 'C'

Stolberg-Stolberg was a tiny imperial county in the Harz region ruled jointly by co-lords for much of its history, and the 1763–64 dates place this coin squarely in the immediate aftermath of the Seven Years' War — a period when dozens of small German states scrambled to restore depleted silver coinages disrupted by wartime financial chaos. The 'C' mintmark denotes Christiansbrunn, the county's own small mint operation.

Frederick Botho and Charles Louis governed as co-counts under the complex partage system typical of Stolberg family succession. Joint-reign issues from minor Harz counties of this period are frequently underdocumented, and Friederich#1995 remains the primary specialist reference for distinguishing die marriages within this short two-year run.
