1 Heller

Frankfurt's heller coinage of this period derives from the Heller — originally minted at Schwäbisch Hall — which became so ubiquitous in the Holy Roman Empire that it functionally defined the smallest unit of account across much of medieval Germany. Frankfurt, holding imperial city status, exercised the minting rights that came with it, producing issues whose dating range spans the reigns of Charles IV, including the years immediately following the Golden Bull of 1356, which codified imperial electoral structure but left smaller city mints largely to their own administrative devices.
