4 Centavos de Córdoba on P#43b

This note belongs to the period when Nicaragua's monetary system was in open crisis. The córdoba replaced the peso in 1912 — the same year this note was issued — as part of a broader financial reorganization carried out under heavy U.S. influence, with American advisors effectively directing Nicaraguan fiscal policy following the Knox-Castrillo Convention of 1911.

The overprint on P#43b is the origin of the fractional denomination: an existing plate was pressed into service rather than commissioning a new design, a cost-saving measure that also reflects the urgency of getting small-denomination notes into circulation quickly during the currency transition. ABNC's involvement ensured technical quality the local treasury couldn't have produced domestically.
