100 Dollars / 20 Pounds, 16 Shillings, and 8 Pence

The dual denomination — $100 and its sterling equivalent of £20 16s 8d — reflects the transitional monetary reality of early twentieth-century Canada, where exchange transactions between dollar and pound accounts were still common enough to warrant printing both values on the face of a high-denomination commercial note. By the early 1920s that practice was dying out, and the Royal Bank quietly abandoned sterling co-denominations on subsequent issues.

The American Bank Note Company's Ottawa facility, rather than its New York plant, handled production — a distinction that matters for provenance, as Ottawa-printed ABNCo work from this period is less extensively catalogued than New York output.
