Biafra's coinage was issued in 1969, deep into a civil war the secessionist state was already losing. By that point, the territory controlled by Biafra had been reduced to a fraction of what it held at independence in 1967, and the humanitarian crisis — the famine that would kill an estimated one to three million people — was well underway. These aluminium pieces saw almost no meaningful circulation; the economic infrastructure to use them barely existed.

KM#1 designates this as the foundational type of an entire national coinage program that effectively died with the republic in January 1970.
