4000 Escudos Chileno Antarctic Chilean Territories

Chile's Antarctic territorial claim — covering the wedge between 53°W and 90°W longitude — has been formally asserted since 1940, overlapping substantially with British and Argentine claims in one of the most legally unresolved sovereignty disputes still active today. The Antarctic Treaty of 1959 froze all territorial claims without resolving them, meaning Chile's position remains in a kind of permanent diplomatic suspension.

The escudo denomination itself was retired in 1975, replaced by the peso at a rate of 1,000 escudos to one peso during Pinochet's economic restructuring. Issuing a 2024 coin denominated in escudos is purely commemorative fiction — no such currency has legal tender relevance in any practical sense.
