24 Mariengroschen - Louis Rudolph

Louis Rudolph ruled Brunswick-Wolfenbüttel from 1731 until his death in 1735, having spent the preceding decades as Duke of Blankenburg — a title he held under the shadow of his more politically prominent relatives in the Hanoverian line. The 24 Mariengroschen denomination was a workhorse of northern German commerce, fixed at two-thirds of a Reichsthaler under the Leipzig Foot monetary convention of 1690, which standardized coinage across much of the Protestant north and remained the practical framework for Brunswick issues well into the eighteenth century.

Louis Rudolph's reign was short and his coinage correspondingly limited in variety, which keeps the four-year emission window tight.
