24 Mariengroschen - August William

August William ruled Brunswick-Wolfenbüttel from 1714 until his death in 1731, a reign defined largely by financial strain and the principality's complex obligations within the Lower Saxon Circle. The 24 Mariengroschen was a workhorse denomination in the fractional silver system of the north German states, where the Mariengroschen — reckoned at 1/36 of a Reichstaler — created arithmetic headaches that persisted until monetary reforms later in the century.

Brunswick coinage of this period was struck at Zellerfeld, the mint that had served the Guelph territories since the sixteenth century on the back of Harz mountain silver production.
