100 Nuevos Soles Machu Picchu

Peru's commemorative coin program has produced dozens of issues tied to its UNESCO World Heritage Sites, and this piece belongs to that ongoing series. The Machu Picchu citadel was largely unknown outside Andean communities until Hiram Bingham III's 1911 expedition brought it to international attention — though local farmers had been working land around the site for years prior and guided Bingham directly to it.

Silver-plated copper-nickel is an economy composition for a face value of 100 Nuevos Soles — a denomination that itself became obsolete when Peru redenominated to the Sol in 2015, making the stated value a anachronism on a coin issued six years after the currency unit ceased to exist.
