2 Pfennig - Charles Frederick

Charles Frederick ruled Saxe-Weimar-Eisenach from 1828 until his death in 1853, presiding over a duchy already distinguished by its outsized cultural reputation — Goethe had spent decades at his father's court. The 1830 issue landed in a politically charged year; the July Revolution in France sent ripples through the German states, prompting scattered unrest and accelerating constitutional debates across the Thuringian duchies.

Saxe-Weimar-Eisenach had been among the first German states to grant a constitution, back in 1816.
