KM#221.2c falls within the broader 20 Centavos series that Peru minted through several compositional changes across the mid-twentieth century, shifting between brass and copper-nickel as global metal prices and domestic fiscal pressures dictated. The .2c suffix distinguishes this from earlier variants in the same physical format, reflecting a deliberate alloy adjustment rather than a redesign.
Peru's monetary policy during this window was shaped partly by the reformist economic pressures of the Prado Ugarteche administration and then the military junta that followed 1962 — coin production continued without interruption through the political turbulence.
