500 Sucres

The Banco Central del Ecuador's 500 Sucres series spans an unusually long print run — over two decades with the same basic plate design from ABNC, a firm whose relationship with Ecuadorian issuers stretched back to the 1920s. During this period Ecuador pegged the sucre to the US dollar under the 1944 monetary reform framework, which partly explains why a high-denomination note could remain in continuous issue without redesign: the monetary environment was comparatively stable by regional standards.

Known date varieties within this series attract more collector attention than the base type itself. Signature combinations changed multiple times across the run, and early 1940s examples differ meaningfully from issues of the early 1960s despite sharing the same ABNC plate origin.
