250 Dollars - Charles III Iron Man

Niue has operated as a prolific licensing hub for pop-culture bullion since the early 2010s, contracting with the New Zealand Mint to produce legal-tender issues under its sovereignty while retaining none of the distribution infrastructure itself. The Iron Man license here falls under Marvel's broader agreement with the NZ Mint, which has covered dozens of characters across multiple precious metal formats.

One troy ounce of .9999 gold at face value of $250 NZD — a denomination with no relationship to actual legal tender utility on an island of roughly 1,500 people.
