50 Vatu Voyager 1

Vanuatu issued this piece as part of a broader wave of commemorative silver coinage that Pacific island nations adopted in the late 1980s and early 1990s — a revenue strategy made possible by licensing agreements with foreign minting houses rather than any domestic minting capacity. The Voyager 1 subject is purely commercial, timed loosely to ongoing public interest in the probe's interstellar trajectory rather than any specific mission anniversary in 1992.

Voyager 1 had by that point crossed the orbit of Pluto, already over a decade into a journey with no scheduled terminus.
