2 Dollars - Charles III Pluto

Niue has operated as a reliable vehicle for New Zealand-backed commemorative silver programs since the 1990s, licensing its issuing authority to foreign mints and distributors with virtually no restriction on subject matter. This coin is part of that arrangement — the sovereignty is nominal, the distribution chain is commercial, and the subject has no meaningful connection to the issuing territory.

Pluto was reclassified as a dwarf planet by the IAU in August 2006, a decision that remains contested among planetary scientists.
