10 Centavos

El Salvador's monetary system through much of this period was structurally tied to the colón, introduced in 1919 to replace the peso at par following years of coffee-export instability. The Banco Agrícola Comercial, later supplanted by the Banco Central de Reserva established in 1934, managed coinage policy through decades of agricultural monoculture dependence and periodic fiscal stress. This 10 centavos type ran across that entire institutional transition without a redesign — a striking degree of continuity for a nation that changed governments by force on multiple occasions during the same span.
