Description and research notes
Specimen of the 2004 Northern Bank £50, printed by De La Rue for Northern Bank Limited, Belfast. This pre-issue design was the last note prepared before the bank’s December 2004 robbery, the largest cash theft in UK history. The note carries the red SPECIMEN overprint and the oval NO VALUE control stamps, serial DA000000 001, and watermark of Sir Samuel C. Davidson (1846-1921), the inventor and industrialist who founded Sirocco Engineering Works and appears on all high denominations of the series.
Issued only to test plate work and approval quality, this 2004 £50 never reached the public. When £26.5 million was stolen from the bank’s cash centre in Belfast on 20 December 2004, Northern Bank immediately recalled its currency and suspended distribution of this issue. The robbery forced an emergency redesign, security overhaul, and complete reissue of Northern Bank notes in early 2005 to maintain confidence in the currency.
Historically, this specimen represents the final appearance of the pre-robbery layout: De La Rue’s guilloché and microtext design with latent numerals, holographic foil stripe, and complex underprint—hallmarks of early twenty-first-century security printing. Survivors are scarce and serve as reference material for the transition between the withdrawn 2004 and the replacement 2005 series. Graded PMG 63 Choice Uncirculated.
