10 Dollars - Elizabeth II Martyrdom

Niue has operated as a prolific license issuer for commemorative coinage since the 1990s, with the New Zealand-administered territory generating revenue by contracting designs to outside mints — predominantly the Polish Mint in Warsaw, which struck the bulk of Niue's collector output during this period. The "Martyrdom" designation almost certainly places this within a themed religious series, likely tied to canonization anniversaries or Catholic martyrology, a recurring subject in Polish mint programming given the domestic market's appetite for such issues.

At 7.78g of .9999 fine gold, this is a quarter-ounce equivalent — a format that saw sharp demand growth in the late 2010s collector market.
