5 Rufies Outer islands of Mauritius

The "Outer Islands" designation covers Agaléga, Saint Brandon (Cargados Carajos Shoals), and the Tromelin dispute — the last of which remains a point of active diplomatic friction between Mauritius and France, with Mauritius asserting sovereignty under a 1965 agreement it considers illegitimate. That same year, Britain detached these territories from Mauritius to form the British Indian Ocean Territory, a move the Mauritian government has never accepted as lawful. The 5 Rufiyaa denomination places this issue within the Maldivian currency system, which is almost certainly an error in the catalog data — Mauritius uses the rupee.
