100 Escudos 9th. print

By the mid-1980s this note was already ageing out of Portugal's post-revolutionary monetary reorganization. The 100 Escudo denomination had been in continuous issue since the early 1960s, and De La Rue had supplied successive printings across the entire run — the 9th print represents the tail end of that relationship before the series was retired entirely. Portugal's accession to the EEC in January 1986 accelerated pressure to modernize the currency's security architecture, and the watermark-only protection on this issue looked increasingly inadequate by the standards of the period.
