⅔ Thaler - Frederick Botho and Charles Louis

Stolberg-Stolberg was among the smallest of the German imperial counties, and by the mid-eighteenth century its ruling house had long practiced partition, dividing governance between co-ruling counts rather than consolidating authority. Frederick Botho and Charles Louis issued jointly under this arrangement. The two-thirds thaler denomination itself was a north German convention, pegged to the Leipzig monetary standard of 1690, which set 12 two-thirds thalers to the Cologne mark of silver — a system still functioning in Stolberg's mints three-quarters of a century after its adoption.
