The naira was introduced on 1 January 1973, replacing the pound at a rate of 2 naira = 1 pound. This made Nigeria the last country to abandon the £sd currency system. There was a plan to redenominate the naira at 1 new naira = 100 old naira in 2008, but the plan has been suspended. The currency sign is ₦ NAIRA SIGN.
