1½ Euro - Mayotte Pattern

Mayotte's status in 2004 was genuinely unresolved — a French territorial collectivity that had voted repeatedly to remain French while the Comoros officially claimed sovereignty over it. The island would not become a full French département until 2011. This pattern was struck by the Monnaie de Paris as part of a speculative euro denomination series that never advanced to circulation, exploring what a 1½ euro coin might look like for overseas territories with ambiguous political standing.

The 1.5 euro denomination itself had no institutional backing from the ECB and was never seriously proposed for adoption.
