20 Soles Oro

Peru's 20 Soles Oro gold piece was part of a coinage system anchored to the sol de oro, a currency unit introduced in 1931 to replace the libra peruana following the country's monetary reorganization after the Great Depression. The design and specifications were held consistent across nearly four decades of production, which itself reflects how stable — by Andean standards — Peru's mid-century finances remained compared to neighbors like Bolivia and Chile, both of whom underwent significant currency revaluations during the same period.

KM#229 spans a long production window, and individual year issues vary considerably in mintage. The 1965 and 1966 dates are notably scarcer in high-surviving populations.
