1 Heller - Conrad III of Dhaun Hohlringheller

Conrad III of Dhaun served as Archbishop of Mainz from 1419 to 1434, a tenure marked by the archbishopric's chronic indebtedness and its complicated position between the competing pressures of the Hussite wars and internal imperial politics. The Hohlringheller — a thin, concave bracteate-style small denomination — was the workhorse of petty commerce in the middle Rhine region, struck in quantity precisely because the denomination wore and was lost faster than it could be produced.

Walther 121 is among the more precisely documented of Conrad's heller issues, though attribution of these types to specific years within the reign remains difficult given the absence of dated dies.
