10 Sucres

The Banco Central del Ecuador relied heavily on the American Bank Note Company for its mid-century paper issues, and this 10 Sucres falls within a series that ran across nearly two decades with minimal design revision — a span that makes precise dating of individual specimens difficult without examining the serial prefix and signature combination. ABNC's New York intaglio work for Ecuadorian issues during this period was technically consistent, if commercially routine.

Ecuador's sucre had been pegged to the US dollar at 15:1 since 1932, a rate that held with remarkable stability through most of this note's circulation window before exchange pressures in the early 1980s ultimately undid it.
