1 Sucre

Banco Suramericano was a short-lived Ecuadorian private bank whose note-issuing privileges were curtailed as the central banking reforms of the early 1920s consolidated monetary authority away from regional institutions. This 1 Sucre was among the lower denominations issued during the bank's final active period, when smaller notes bore the heaviest circulation burden and consequently suffered the most wear.

Pick S251 falls within the private bank series for Ecuador — comparatively thin in surviving populations given the redemption pressures that followed the 1927 establishment of the Banco Central del Ecuador, which effectively made predecessor private bank notes redundant.
