1 Heller - William IX

William IX inherited Hanau-Münzenberg in 1760 at age nine, with administration handled by regents until he came of age. These small copper hellers were among the last coins struck under the Hanau-Münzenberg name — when William later inherited Hanau-Lichtenberg in 1775, the two counties merged and the separate Münzenberg coinage ceased entirely. He would go on to become Elector Wilhelm I of Hesse-Kassel, notorious for lending Hessian troops to the British during the American Revolutionary War and profiting handsomely from the arrangement.
