1 Groschen - Adolphus I Kleve

Adolphus I ruled Cleves during a period of territorial consolidation along the lower Rhine, and his groschen issues reflect the broader adoption of the Flemish gros model that was reshaping regional currency across the Low Countries in the second half of the fourteenth century. Cleves at this point was not yet a duchy — that elevation came only in 1417 — and these coins circulated in a county still asserting itself among competing Rhine lordships.

The Noss Be#87 reference places this within Bernhard Noss's foundational typology of Cleves coinage, still the standard classification for the series.
