5 Dollars - Elizabeth II Matterhorn

The Cook Islands has issued small-format gold pieces under its own authority since the 1970s, a practice made possible by its status as a self-governing territory in free association with New Zealand — giving it full power to issue currency while New Zealand retains responsibility for defense and foreign affairs. The Matterhorn, straddling the Swiss-Italian border, has no political connection to the Cook Islands whatsoever; its appearance here reflects the modern bullion and collector market's appetite for iconic imagery rather than any numismatic or geographic logic.

At 0.5 grams, this is essentially a novelty fractional, priced on melt plus a substantial premium.
