Cayman Islands 1974 - Cayman Islands Currency Board 1 Dollar Issued Note (Pick 5e)

The obverse is built around a deliberately conservative composition typical of late twentieth century Thomas De La Rue and Company Limited output for British overseas territories. Queen Elizabeth the Second appears at right in a dense engraved portrait field designed to anchor the note’s authority visually and to concentrate anti-counterfeiting linework in a single high-information zone. At center, the Cayman Islands coat of arms is integrated into a bold denomination panel reading One Dollar, a layout that privileges immediate denomination recognition while preserving an uncluttered field for security patterning. Beneath the central panel, the note bears the engraved signature of A. Jefferson, serving as Chairman of the Cayman Islands Currency Board at the time of this printing. The printed serial number 105218 with prefix A/6 occupies the left and right serial positions, providing the operational identity of this specific note within the printed run. Read more →
