1 Heller - Frederick I

Frederick I of Hesse-Cassel spent most of his reign also serving as King of Sweden — a dual role that left the landgraviate administered largely by his wife Maria Amalia and a regency council. The heller, by the mid-eighteenth century, was the smallest denomination in regular circulation, worth half a pfennig, and copper issues of this period frequently saw prolonged use simply because there was nothing smaller to replace them with. Wear on surviving examples is almost universal.
