25 Centavos Countermarked

Spanish colonial 20 Centavos pieces circulating in Cuba were officially countermarked and revalued to 25 Centavos by decree during the 1870s, a direct response to chronic small change shortages that plagued the island throughout the Ten Years' War. The revaluation allowed Spain to stretch existing coinage without a full reminting program while the colonial economy strained under the costs of suppressing the independence revolt that had begun in 1868.

KM#R4.3 specifically denotes the countermark applied over coins of particular host types — the cataloged variety distinctions hinge entirely on the origin and date of the host coin, not the countermark itself.
