Description and research notes
This one hundred dollars specimen of the Cayman Islands Currency Board belongs to the 1991 series issued under the Cayman Islands Currency Law (Revised) and produced by Thomas De La Rue and Company Limited as controlled reference material. It preserves the fully authorized production design of the denomination while being permanently invalidated for non-monetary use through layered printer control measures.
The specimen format follows De La Rue’s established control protocol. A bold red diagonal SPECIMEN overprint crosses the face, accompanied by two red oval control stamps reading “SPECIMEN / DE LA RUE & CO LTD / NO VALUE.” A single punch cancellation is present in the signature area, physically voiding the note while leaving the engraved composition fully legible. At the lower margin, the printed tracking panel reads “SPECIMEN No. 049,” identifying its place within the controlled specimen documentation of this denomination.
The serial format carries prefix B/1 with the all-zero serial number 000000, a configuration reserved exclusively for specimen handling and never used for circulation output. The engraved signature beneath the central denomination panel is that of A. Jefferson, serving as Chairman of the Cayman Islands Currency Board during the 1991 series, anchoring the note within its correct administrative phase.
The obverse presents Queen Elizabeth the Second in refined intaglio engraving at right, balanced by marine motifs and the Cayman Islands coat of arms integrated into the denomination panel. The layered background coloration and controlled use of pastel tonal fields reflect the evolved security aesthetic of the early 1990s Cayman series.
The reverse depicts the harbor scene of George Town, capital of the Cayman Islands, rendered in detailed line engraving with structured perspective and architectural layering. Marine vessels, shoreline buildings, and controlled ornamental framing produce a balanced field of engraving density that merges national identity with disciplined security printing logic. The ornamental denomination cartouches at left and right maintain symmetry and visual stability across the design.
As a specimen, this note functions as institutional reference material rather than currency. It documents the finalized 1991 one hundred dollars design together with the exact invalidation tools applied by Thomas De La Rue to distinguish archival specimen impressions from live monetary production.
