1 Thaler - Johann Christian and Johann Seyfried Krummau

The House of Eggenberg held Krummau (now Český Krumlov) as a Bohemian princely fief, and this thaler was struck jointly in the names of Johann Christian and Johann Seyfried — two brothers ruling their territories in co-lordship, a dynastic arrangement increasingly rare by the mid-seventeenth century. The timing falls just a decade after the Peace of Westphalia ended the Thirty Years' War, which had devastated Bohemian noble families aligned with the Habsburgs far less than those who opposed them; the Eggenbergs had backed the right side and were richly rewarded with lands and titles.

The family line died out in 1717, making all Eggenberg coinage terminal — no continuation issues, no successor mint.
