1/2 Batzen

Isny im Allgäu held Imperial Free City status from 1365, giving its civic government the right to strike coin — a privilege jealously exercised and occasionally contested by neighboring ecclesiastical authorities. The Batzen denomination itself was a relatively recent innovation in 1508, having emerged from Swiss minting practice in the 1490s and rapidly spreading across southern Germany and the Alpine borderlands as trade demanded a practical silver multiple above the pfennig but below the gulden.

The Nau reference spanning numbers 38 through 47 suggests meaningful die variation across the type, worth cross-referencing against Schultze before attributing any single piece.
