1 Heller - John I Möhrchen

John I, called "Möhrchen" — a nickname whose exact origin remains disputed but likely derives from a regional term — ruled Cleves during a period of persistent friction with neighboring territories over Rhine toll rights. The heller denomination by the mid-fifteenth century had been so debased across the Rhineland that many issuing authorities were striking coins barely distinguishable from copper, making a silver heller from this period a minor but deliberate statement of monetary credibility.

The Noss classification for this type is among the thinner-documented entries in Rhenish minor coinage literature.
