500 Francs

Adélie Land has no permanent civilian population and no functioning local economy — these coins are legal tender in name only, issued under the administrative umbrella of the French Southern and Antarctic Territories (TAAF) and sold directly to collectors. The TAAF has leaned heavily into numismatic programs since the 1990s as a revenue stream, with Adélie Land issues among the more collectible given the territory's specific association with French Antarctic exploration dating to Dumont d'Urville's 1840 expedition.

No coin of this type has ever been spent on anything.
