80 Dollars - Elizabeth II Queen Elizabeth II

Niue's status as a Cook Islands-adjacent Pacific microstate with a population under 2,000 has made it one of the most prolific issuing authorities in modern numismatics — not because its residents need the coinage, but because New Zealand manages its external affairs while leaving monetary licensing largely open. The result is a near-limitless stream of large-format silver issues nominally denominated in Niuean dollars, a currency that exists almost exclusively on collector pieces.

At a kilogram and 100mm across, this is a bullion-adjacent format produced specifically for the high-end gift and investment market that emerged strongly in the early 2020s.
