3 Heller - William II and Frederick William

Hesse-Cassel's currency in this period occupied an awkward position: the electorate used its own coinage while being surrounded by states rapidly converging on the monetary agreements that would eventually produce the Vereinsthaler. The dual-authority naming — William II and his son Frederick William as co-rulers — reflects the practical regency arrangement forced by William II's prolonged incapacity from 1831 onward, with Frederick William handling actual governance while his father's name remained constitutionally necessary on official issues.
