1 Dollar - Elizabeth II Christmas star

Niue has operated a prolific bullion and commemorative program since the 1990s, licensing its sovereignty to private mints — primarily the New Zealand Mint — in exchange for royalty revenue. The arrangement is straightforward economics: a nation of roughly 1,600 people generates meaningful income from a face value that no one ever expects to spend.

The .9999 fineness places this above the more common .999 standard, a specification the New Zealand Mint adopted selectively for premium collector issues in this period.
