25 Dollars

The Oriental Bank Corporation was one of the dominant exchange banks operating across the British colonial East — headquartered in London but with active branches from Bombay to Yokohama. Its Hong Kong branch issued notes in limited denominations to facilitate trade settlement, and this 25-dollar value is among the less common from the series, reflecting the specific transactional demands of the colony's merchant community rather than round-figure convenience.

The bank collapsed in 1884, rendered insolvent by bad loans tied to coffee speculation in Ceylon. Outstanding notes became worthless almost overnight.
