100 Soles de Oro Casa de Moneda

Peru's 100 Soles de Oro gold piece was struck at the Lima mint — the Casa de Moneda de Lima, one of the oldest operating mints in the Western Hemisphere, having produced coinage continuously since 1565. By 1965, the Soles de Oro had been Peru's monetary unit for nearly four decades, but chronic inflation was already eroding its purchasing power in ways that would accelerate dramatically through the 1970s and eventually force a complete currency replacement with the Inti in 1985.

At just over 46 grams of .900 gold, this was a substantial bullion-adjacent denomination rarely seen in everyday commerce.
