1⁄12 Thaler - George IV

George IV never set foot in Hannover as king. His father George III had been barred from the kingdom by Napoleonic occupation and then by his own deteriorating mental state, and George IV — despite being the first Hanoverian monarch to actually visit the continent — made his 1821 trip to Hanover before this series began striking. The kingdom operated as a fully separate personal union, administered by a viceroy, meaning these coins were produced under royal authority that was in practice entirely absent.

Billon at .437 fine was a deliberate step down from earlier Hanoverian silver fractions, reflecting postwar fiscal strain across the German states in the early 1820s.
