1 Ducat - George III Harz - Mining Dukat

The Harz mining ducats of Brunswick-Lüneburg were struck directly from gold sourced in the Harz Mountains, a practice with roots in the sixteenth century that gave these issues a distinct institutional identity separate from general coinage. The region's mines, administered under the Oberbergamt at Clausthal, supplied the metal and effectively sponsored the coins — hence the mining attribution. By 1802, output from the Harz workings had been declining for decades, and these late George III issues were produced in comparatively small numbers against that contracting backdrop.

The Fr#618 reference places this squarely within a recognized ducat type, but the Müseler citation is the more useful one for serious collectors — Müseler's exhaustive treatment of German mining coinage remains the definitive work for distinguishing the subtle die variations within this short-lived series.
