100 Dollars Colonial Bank

The Colonial Bank was a British overseas bank chartered in 1836 to serve the Caribbean, operating branches across Barbados, Trinidad, British Guiana, and several smaller islands. By 1907 the bank was in its final institutional decades — it was absorbed into Barclays Bank (Dominion, Colonial and Overseas) in 1926, taking its entire note-issuing history with it.

Perkins, Bacon & Petch had long been the default choice for colonial currency printing, their steel intaglio work considered difficult to counterfeit in regions where sophisticated forgery detection was limited. The watermark was essentially the primary security layer in daily use.
