1 Dollar - Elizabeth II Mars

Niue has functioned for decades as a licensing vehicle for the New Zealand-administered collector coin market, issuing bullion and themed pieces under agreements that bear no relation to the island's roughly 1,500 residents or their economy. This Mars-themed dollar is one of hundreds of such issues — the KM catalogue entry alone tells you how industrialized the program has become.

Collector demand for space-themed silver rounds peaked sharply around 2019–2021, driving a wave of nearly identical one-troy-ounce issues from Niue, Cook Islands, and Tuvalu simultaneously.
