1 Thaler - William

Brunswick's Thaler coinage of this period was tied directly to the Dresden Convention of 1838, which standardized the North German Thaler at 22.27 grams and brought a patchwork of competing German state coinages into reluctant alignment. William — Herzog Wilhelm, who had reclaimed the duchy in 1830 after his brother Ernst August's accession to Hanover dissolved their personal union — issued this piece under a monetary framework he had little hand in designing.

The .750 fineness was below that of many contemporary Prussian issues, a compromise baked into the Convention itself.
