In this paper an attempt is made to combine contemporary field work with historical data in the study of certain early currency systems of Southern Nigeria with special reference to the Rivers Province.
My historical sources for the period up to the eighteenth century are Pacheco Pereira, Dapper, and John and James Barbot, mainly the last three; for the early nineteenth century mainly Captains Adams and Bold, together with the other sources detailed in the bibliography. For ethnographical data I have had to rely on Talbot supplemented by my own work during the period 1927 to 1946; and during a period of more recent field work in the Rivers Province and Old Calabar in 1956 I was able to make a specific study of the traditional political and economic systems of the Oil Rivers Ports.
