4 Pfennige - Charles August

Saxe-Weimar-Eisenach under Charles August was a culturally outsized duchy — Goethe administered its finances and roads while Napoleon reshaped its borders. The 1808 Confederation of the Rhine reorganization elevated the duchy's status and prompted a rationalizing of its petty coinage, which is the direct administrative reason this copper Pfennig denomination exists in this form.

KM#163 is not scarce, but survivors in problem-free condition are harder to find than mintage suggests — copper of this weight circulated hard in a region where small change was chronically short.
