2 Pfennige - William

William, Duke of Brunswick, assumed rule in 1830 only after his brother Charles II was driven out by a popular uprising — Brunswick being one of the few German states where the 1830 revolutionary wave actually toppled its ruler. This copper issue belongs to the last decade of William's reign, struck as the German states were moving toward the monetary unification that would eventually render such small-denomination duchy coinage obsolete. The KM#1155 type had a short production window of just two years before the series was superseded.
