2 Dollars = 10 Shillings

The Bank of British North America was chartered in London in 1836 and operated as a British imperial institution rather than a locally incorporated colonial bank — a distinction that shaped everything from its capital structure to its note designs. Perkins, Bacon & Co. produced engraved work of consistently high quality for colonial issuers, and their security printing for BBNA benefited from the same steel-engraving techniques they applied to postage stamps.

The dual denomination — dollars and shillings on the same face — reflects the genuinely chaotic monetary arithmetic of mid-nineteenth-century British North America, where Halifax currency, York currency, Spanish dollars, and sterling all circulated simultaneously in overlapping and incompatible systems.
