1 Rupee

Zanzibar's first government currency issue, P#1 was printed by De La Rue in London shortly after the island's administration moved to formalize a local paper currency distinct from the broader East African series. Zanzibar's status as a British Protectorate — technically separate from British East Africa — gave it the authority to issue its own notes, and 1920 was the first exercise of that authority.

Both signatories were colonial civil servants rather than central bankers. Sinclair as Chief Secretary and Davis as Treasurer co-signed in an arrangement that would persist for the short life of this series before the East African Currency Board absorbed regional issuances.
