5 Dollars - Elizabeth II Saint George

Niue's status as a Cook Islands-adjacent Pacific microstate with a population under 2,000 gives it virtually no domestic coin demand — its entire numismatic output exists for the international collector market, funded through a licensing arrangement with New Zealand. The 2014 Saint George issue is part of a broader wave of gold-plated silver 2 oz pieces that flooded the commemorative market in the early 2010s, when sovereign mints and private producers alike rushed to exploit collector appetite for oversized bullion-adjacent issues at accessible price points.
