New Zealand 1907–1926 - Bank of New Zealand £20 Blue Serial-Prefix Audit Specimen (Pick S194s)
A unique high-denomination Bradbury Wilkinson audit-range specimen and the rarest surviving document from New Zealand’s private-banknote era, the £20 Blue (Pick S194s) represents the apex of BNZ’s color-coded denomination hierarchy. This specimen is not a generic zero-serial example: it carries dual live serials (No. 061001 and No. 066000), identifying it as an internal audit-range piece used by Bradbury Wilkinson for plate alignment, tint calibration, and numbering verification during the official approval process.
