Regensburg's status as a Free Imperial City gave its mint the right to strike gold, a privilege jealously guarded and periodically contested by neighboring ecclesiastical powers throughout the eighteenth century. The city was simultaneously home to the Immerwährender Reichstag — the permanently sitting Imperial Diet that relocated there in 1663 and never left — making Regensburg one of the most politically peculiar municipalities in the Holy Roman Empire during this span.

The twenty-year date range reflects sequential die use rather than a continuous uninterrupted run, with individual years varying considerably in output.
