The Bank of Nassau was a private commercial bank — not a government institution — chartered under Bahamian law and issuing its own notes in competition with British colonial currency during the late Victorian period. That arrangement was already unusual for a territory of its size, and the bank's circulation privileges were tightly constrained by the colonial administration in London.

The A4B designation suggests a sub-variety within the series, likely differentiated by signature combination or minor plate revision. Pick listings for this issuer are thin, and surviving examples are genuinely rare — the bank's total note-issuing lifespan was short, and Bahamian humidity is not kind to cotton-substrate paper left in circulation or private storage.
