2 Dollars 50 Cents - Elizabeth II Dwight D. Eisenhower

Niue has operated as a Pacific micro-state licensing arrangement since the 1990s, issuing gold and silver collector pieces under New Zealand's oversight while generating revenue through numismatic sales rather than circulation. This half-gram format — essentially a novelty bullion fragment — became commercially viable only after advances in small-diameter die technology made sub-gram gold strikes economically practical for private mints around 2010.
