50 Céntimos Without braille

Peru's coinage for the visually impaired was introduced in the 1990s when the central bank added tactile dots to circulating coins — a relatively early adoption of such features in Latin America. This piece represents a production run deliberately manufactured without those markings, a variant that emerged through inconsistent die preparation rather than any policy reversal. The KM#307.4 designation distinguishes it from the standard braille-inclusive type, and examples surface frequently enough to suggest the omission was not isolated to a single striking.
