5 Dollars Colonial Bank

The Colonial Bank operated across the British West Indies and British Guiana for over a century before being absorbed by Barclays Bank (Dominion, Colonial and Overseas) in 1925 — this note dates from the final years of the bank's independent operation. Perkins, Bacon & Co. had an established relationship with colonial banking institutions across the Empire, and their security printing methods, particularly steel engraving and geometric lathe work, were specifically chosen to frustrate local counterfeiting in territories where detection capacity was limited.

Pick S135 is scarcer than the bank's earlier issues, the 1918–1920 window being a period of considerable commercial disruption in the Caribbean tied to post-war commodity price volatility.
