5 Dollars - Elizabeth II John F. Kennedy

Niue has operated as a reliable vehicle for international commemorative issues since the 1990s, its licensing arrangements with foreign mints allowing it to produce legal tender struck at facilities far beyond its 1,600-person population's needs. This Kennedy piece belongs to a broader wave of fractional gold commemoratives — 1/10 oz, .999 fine — that flooded the collector market in the 2010s as spot prices made small-denomination gold viable for impulse buyers.

Kennedy's assassination on November 22, 1963 triggered one of the fastest authorized design changes in U.S. Mint history; the half dollar bearing his portrait entered circulation less than four months later.
