5000 Pesos Islas Desventuradas

The Islas Desventuradas — San Félix, San Ambrosio, and two minor rocks — sit roughly 850 kilometers off the Chilean coast and host one of the most biologically isolated marine reserves in the world, designated in 2016 as part of a 300,000-square-kilometer protected zone. Chile's commemorative program for remote territorial possessions has leaned heavily on this kind of conservation framing since the mid-2010s. Silver-plated copper-nickel at this diameter is a budget collector format, not a circulation issue — these are produced explicitly for the numismatic market rather than any transactional purpose.
