100 Ekueles Corisco island

Corisco is a small island off the coast of Equatorial Guinea with a history tangled between Portuguese traders, Bubi and Benga peoples, and a formal Spanish colonial claim only consolidated in 1843. It has no mint, no significant modern economic infrastructure, and a population that has hovered near zero at various points in the 20th century. This coin does not circulate there in any practical sense — Equatorial Guinea's numismatic program has long operated as a revenue vehicle aimed at collectors rather than commerce, issuing bimetallic pieces referencing obscure administrative territories with effectively no local monetary function.
