Cayman Islands 1974 - Cayman Islands Currency Board 1 Dollar Specimen with Red Overprint (Pick 5as)
The defining invalidation on this example is a single bold red diagonal SPECIMEN overprint applied across the face of the note. This classic specimen format represents the standard presentation form used by Thomas De La Rue for institutional reference and controlled distribution. No additional invalidation devices are present: there are no oval NO VALUE stamps, no perforations, and no punch cancellations. The absence of secondary control marks distinguishes this example from later or more heavily invalidated specimen forms. Read more →
