5 Dollars - Elizabeth II Zhang Fei

Zhang Fei was one of the Oath Brothers of the Peach Garden in the Romance of the Three Kingdoms — the 14th-century historical novel by Luo Guanzhong that remains one of the four canonical masterworks of Chinese literature. His reputation for ferocity is anchored by the episode at Changban Bridge in 208 AD, where he allegedly held off Cao Cao's pursuing army alone, though historians treat the account skeptically. Niue has issued commemoratives under Pacific Island licensing arrangements for decades, functioning as a sovereign vehicle for collector-market silver rather than circulating currency.
