1/2 Gulden - Adolph

Nassau's half gulden series under Duke Adolph was struck to the standards of the Dresden Convention of 1838, which brought a cluster of German states into monetary alignment ahead of any formal political union. The duchy's coinage from this window is often overshadowed by the larger thaler issues, but the half gulden saw genuine commercial circulation across the Rhine frontier trade routes.

Adolph would later become Grand Duke of Luxembourg in 1890 — the last ruling Nassau duke, after the main line's German territories were annexed by Prussia in 1866 as punishment for backing Austria in the Seven Weeks' War.
