1 Dollar - Elizabeth II Galaxy NGC 4321

Niue has issued silver coins under licensing agreements since the 1990s, functioning essentially as a mint-for-hire jurisdiction whose nominal face values bear no relationship to circulation. NGC 4321 — also catalogued as Messier 99 — is a grand design spiral galaxy in Coma Berenices, roughly 55 million light-years distant and one of the first galaxies in which a measurable redshift was recorded, contributing to early 20th-century debates about the expanding universe before that framework was even established.
