In 1974, round cupro-nickel one leone coins were introduced and in 1976, seven sided cupro-nickel 2 leone coins commemorating FAO were introduced. These latter two denominations, however, did not circulate as frequently as the lower cent denominations. The portrait of Stevens also appeared on a new, slightly smaller series of coins introduced in 1980 in denominations of ½, 1, 5, 10 and 20 cents. In 1987, octagonal, nickel-bronze 1 leone coins were introduced with a bust portrait of General Joseph Saidu Momoh. This coin effectively replaced the one leone note.
