5 Colones

ABNC printed this series under contract during a period when most Central American central banks still depended entirely on U.S. security printers — El Salvador had no domestic printing capacity for fiduciary notes of this security level. The Banco Central de Reserva had been reorganized in 1961 following U.S.-backed monetary reform pushed under the Alliance for Progress program, and this issue reflects that political and financial alignment.

P#106 spans several date variants across the 1964–1967 window. Earlier dates in the series tend to be more elusive in higher circulated grades, as the 5 Colones denomination saw heavy everyday use in a cash-dependent economy where banking penetration remained low.
