1 Ducat - Thomas II

Haldenstein was among the smallest sovereign entities in the Holy Roman Empire ever to exercise the right of coinage — a tiny lordship perched above the Rhine valley in what is now the canton of Graubünden. Thomas II of Schauenstein-Haldenstein obtained the minting privilege through imperial grant, and the 1667 ducat was struck in the same year the lordship's political position within the Three Leagues of Grisons was under persistent pressure from both Austrian and French interests competing for influence over the Alpine passes.

The HMZ census records only a handful of surviving examples, placing this among the rarest ducats of the Swiss territorial series.
