5 Dollars / 1 Pound 10 Pence

The Royal Bank of Canada's dual-denomination notes — expressing value simultaneously in dollars and sterling — were issued specifically for circulation in the British Caribbean territories where the bank operated branches, particularly in Trinidad, Barbados, and Jamaica. The £1/10s equivalent was a practical concession to colonies still transacting in pounds rather than dollars.

The American Bank Note Company's Ottawa facility handled the printing, which was relatively unusual — much Caribbean branch currency of this period was produced in New York. By 1920 the dual-denomination practice was already fading; most Caribbean territories had standardized sufficiently that the sterling notation was becoming redundant rather than genuinely useful.
