5 Guaranies black color

The 1963 series marked an early phase of Banco Central del Paraguay's note production following the institution's establishment in 1952, with Thomas De La Rue handling the contract — a common arrangement for Latin American central banks that lacked domestic printing infrastructure at the time. The "black color" designation distinguishes this from later printings of the same P#195 type issued in different color variants, a cataloging distinction that matters more than it might appear given how frequently the two are conflated in collections.

Colmán Villamayor and Acosta's signatures place this issue within a narrow administrative window, useful for dating undated or ambiguously dated examples from this period.
