5 Dollars = 25 Shillings

The Niagara Suspension Bridge Bank was a short-lived Upper Canadian institution operating out of Queenston, a village at the base of the Niagara escarpment that had once been the principal entry point into Upper Canada before the War of 1812 reduced it to a backwater. The dual denomination — dollars and shillings — reflects the genuinely chaotic monetary arithmetic of pre-Confederation Canada, where American dollars, British sterling, and Halifax currency all circulated simultaneously and merchants priced goods in whichever unit suited them.

The bank itself was never a major issuing institution, which makes surviving notes from this 1841 series genuinely uncommon.
