2 Vierer - Ferdinand II of Tyrol

Ferdinand II ruled Tyrol and the Further Austrian territories — including Upper Alsace — as an archduke rather than as emperor, a distinction that gave him unusual latitude in local monetary policy. The Vierer denomination was a workhorse of small-change commerce in the Rhine borderlands, where French, Swiss, and Imperial coinages circulated simultaneously and the chronic shortage of low-denomination silver kept billon issues like this one in constant demand.

The eleven-year production window suggests steady recoinage rather than a single authorization — replacement of worn stock was an ongoing administrative necessity in this region.
