25 Dollars - Elizabeth II Bismarck

The Bismarck Archipelago takes its name from Otto von Bismarck, who never visited the islands — the nomenclature was a deliberate political gesture by the German colonial administration in 1884, intended to flatter the Chancellor into supporting continued Pacific expansion. Germany held the territory until Australian forces seized it in the opening weeks of World War I, a campaign completed in less than a month. The Solomon Islands issued numerous silver commemoratives in the early 2000s drawing on Pacific theater history and geography, with KM# 261 falling squarely within that series.
