The North Western Bank of India was a short-lived private bank operating out of British India, and a 50 Dollar denomination — rather than Rupees — points to the ambitions of its founders to service merchant trade across multiple currencies and ports. The dollar unit was common in Indo-Pacific commercial banking of the period, reflecting the dominance of Spanish and later Mexican dollars in regional trade circuits.
