10 Sucres

The Banco Central del Ecuador began issuing its own notes only in 1927, after the bank's creation as part of the Kemmerer Mission reforms — a US-led monetary stabilization program that swept through several South American countries in the 1920s. Before that, private commercial banks had issued Ecuador's circulating paper. The ABNC relationship that produced this series was a direct consequence of that American-led restructuring.

The sucre held reasonable stability through most of this note's issue window, though wartime import restrictions and postwar inflation steadily eroded purchasing power by the late 1940s. Notes from this series often show heavy circulation wear, consistent with a denomination that saw genuine everyday use.
