50 Escudos 7th. print, 1st. type

Thomas De La Rue printed multiple generations of Banco de Portugal notes throughout the mid-twentieth century, and this 50 Escudos belongs to a long-running series that stretched across nearly a decade of issue dates. The "7th print, 1st type" designation reflects Portugal's practice of reissuing fundamentally identical designs with updated signatures and date ranges rather than commissioning fresh artwork — a cost-conscious approach that makes precise attribution dependent on the signature combination and date rather than any visible design change.

Pick 160 is common in circulated grades; high-grade examples are harder to place than their frequency suggests, as the note's relatively modest denomination meant heavy everyday use.
