1/2 Gulden

Frankfurt's half gulden of this period was struck under the monetary framework established by the 1838 Dresden Convention, which created the South German gulden standard and obligated member states — including the Free City — to align their coinage with a common weight and fineness. For a city-state whose commercial identity depended on being acceptable currency across the German confederation, conformity was not a bureaucratic exercise but a practical necessity.

The Free City lost its independent status entirely in 1866 when Prussia annexed it following the Austro-Prussian War, ending centuries of municipal coin production at a stroke.
