100 Pesos

Banco Nacional del Salvador was the dominant note-issuing institution in El Salvador from its founding in 1891 until the creation of the Banco Central de Reserva in 1934, which absorbed its functions and terminated outstanding circulation. By 1907, the bank operated under concession from the Salvadoran government and faced increasing competition from other chartered banks also printing ABNCo notes — making the physical similarity between competing issues a genuine problem for merchants at the time.

At the 100 Pesos denomination, surviving examples are rare. High-value notes in small economies tend to spend little time in ordinary hands and more time in commercial settlements, often returning to the issuing bank quickly and being cancelled or destroyed rather than recirculating.
