20 Shillings

The West African Currency Board was a colonial monetary institution serving British West Africa — Nigeria, Gold Coast, Sierra Leone, and the Gambia — but by 1962 its days were numbered. Ghana had already departed in 1958 following independence, Nigeria established its own central bank in 1959, and this series was effectively issued into a dissolving system. The Board was formally wound up in 1964.

Notes from this final period circulated across whichever territories still accepted them, which created practical confusion at borders. Thomas De La Rue had printed for the Board throughout its existence.
