Goslar's groschen coinage of this period derives its authority from the city's control of the Rammelsberg silver mines — one of the richest ore deposits in medieval Europe, worked continuously for over a thousand years. The mines funded Goslar's status as an imperial free city and made local silver coinage a practical necessity rather than a political gesture. By the early sixteenth century, the Rammelsberg's output was already declining, and the city's minting activity contracted accordingly.
