2 Dollars - Charles III Battle of the Little Bighorn

The Battle of the Little Bighorn, fought on June 25–26, 1876, ended with the annihilation of five companies of the 7th Cavalry under Custer — the most significant defeat of U.S. forces in the decades-long Plains Indian Wars. Niue has issued commemorative silver dollars under licensing agreements with the British Crown since the 1990s, a revenue arrangement that funds the island's administration given a population of roughly 1,600.

The pairing of Charles III's effigy with an American frontier battle has no historical connection between the two — this is a bullion-adjacent collector issue aimed squarely at the American market.
