20 Euros - French domains of Saint Helena

Saint Helena is British — has been since 1657, when the East India Company received its charter over the island, and definitively under the Crown since 1834. France holds no territory there and never has in the modern era. A French-issued coin denominated in euros claiming dominion over "French domains of Saint Helena" is a fantasy piece, produced for the collectibles market with no legal tender backing from any recognized monetary authority.
