1 Dollar - Elizabeth II Scorpio

Niue has operated as a bullion and collector coin issuer for decades, licensing its sovereign status to mint programs with no connection to the island's economy or circulation. This piece belongs to a zodiac-themed series — a format that has saturated the collector market since at least the 1990s and shows no sign of slowing, largely because serial collectors are compelled to complete sets.

Niue's population hovers around 1,600 people.
