1 Dollar - Elizabeth II Space Mining

Niue's authority to issue legal tender coinage derives from a 1981 agreement with New Zealand, which remains responsible for the island's defense and foreign affairs. The arrangement has made Niue one of the most prolific sources of themed collector silver in the modern market, with virtually no connection between the coins issued and the 1,600-person population nominally backing them.

The "Space Mining" theme reflects a brief but genuine commercial frenzy around asteroid resource extraction that peaked roughly 2015–2018, when companies like Planetary Resources and Deep Space Industries were attracting serious venture capital before both collapsed or pivoted by 2019.
