Heller - John William

Saxe-Eisenach was one of the smaller Ernestine Saxon duchies, and by 1716 its ruling duke, Johann Wilhelm, was presiding over a territory perpetually squeezed between more powerful neighbors. The heller, essentially the smallest denomination in the German copper currency hierarchy, was struck here in copper precisely because silver was too valuable to waste on fractional coinage that would be handled by the poorest of the population.

Johann Wilhelm died in 1729 without a male heir, after which Saxe-Eisenach was absorbed into Saxe-Weimar — ending the duchy's independent coinage entirely.
