A 440-year-old coin was found under a church. It helped solve the mystery of a colony that vanished

Archaeologists found a 1584 silver coin at a failed Spanish colony in Chile. This founding coin was placed exactly where historical records indicated. The colony, Ciudad del Rey Don Felipe, was abandoned after less than three years. Harsh conditions and lack of resources devastated its approximately 350 settlers. This discovery offers new clues about the settlement's history and layout.
