1000 Francs

Tromelin Island is a French-administered territory in the Indian Ocean with no permanent civilian population — just a rotating French meteorological team of a few personnel at any given time. It has never had a circulating currency of its own. Notes issued under its name are fantasy pieces, produced for the philatelic and notaphilic collectibles market rather than for any monetary authority or administrative function.

The polymer substrate places this squarely in the modern souvenir note tradition, where production values are high and issuing legitimacy is essentially zero.
