4 Dollars = 20 Shillings

The Accommodation Bank was chartered in 1835 and failed spectacularly in 1838, making its entire note issue extraordinarily short-lived. Ontario's pre-Confederation banking environment was notoriously permissive, and the Accommodation Bank was among the more thinly capitalized institutions to receive a charter — its collapse left local merchants holding worthless paper during an already turbulent period shaped by the Upper Canada Rebellion of 1837.

The dual denomination — four dollars expressed alongside twenty shillings — reflects the awkward monetary reality of Upper Canada at the time, where sterling and decimal values coexisted in daily commerce.
