1 Thaler

Isny im Allgäu was a Free Imperial City of the Holy Roman Empire, and its right to strike thalers in the 1550s was exercised during a period of intense municipal assertion — small imperial cities frequently minted silver at this scale precisely to demonstrate autonomous standing, not because local commerce demanded it. Isny's output was modest by any measure, and city thalers of this period survive in genuinely small numbers.

The Davenport reference places this among the earliest documented thaler-weight issues from Isny.
