Start with the legends and portrait. The defining marks of this coin are the words ONE NAIRA around the obverse and the name HERBERT MACAULAY in the lower field, set below a profile portrait of a balding, mustached man. If the coin instead reads a kobo value or lacks the Macaulay name, it is a different denomination or a later type.
Check the reverse for the national emblem. You should see Nigeria's coat of arms, a shield bearing a forked (Y-shaped) white band that represents the country's two great rivers meeting, supported by a horse on each side and crowned by an eagle. This armorial reverse, rather than a plain numeral, helps separate the naira from generic base-metal coins of similar color.
Assess size, weight and metal. The first-series 1 Naira is a broad, substantial copper-nickel coin, noticeably larger and heavier than the small kobo pieces of the same era. It is silvery in tone but non-precious; weigh and measure it and compare against catalog specifications for the type to rule out a smaller later 1 Naira or a foreign look-alike.
Locate the date to pin down the issue. The year of striking sits with the design and places the coin within the early naira series. Circulated examples often show dark toning, spotting or corrosion, as on the photographed coin, so clean the surfaces only conservatively and read the date carefully before assigning any scarcity.
Authentication is seldom a concern at this coin's value, but stay alert for worn or tampered dates and for confusion with the smaller modern 1 Naira. When in doubt, confirm the Macaulay portrait, the ONE NAIRA legend and the coat-of-arms reverse together, and match the diameter and weight to published figures for the copper-nickel type.
Frequently asked questions
How do I tell this from the smaller modern 1 Naira?
The copper-nickel Macaulay type is a large, heavy coin with a portrait obverse. Later 1 Naira coins are smaller and lighter with different designs, so compare size, weight and the presence of the Macaulay portrait.
Where is the coin's country name shown?
Nigeria is identified by the national coat of arms on the reverse and the naira denomination rather than by a large country name; the ONE NAIRA legend and Macaulay portrait confirm the issuing nation.
Where do I find the date?
The year of striking appears with the design and marks the specific issue within the first naira series. Read it carefully on worn coins, since toning and corrosion can obscure the digits.
Should I clean a corroded 1 Naira before identifying it?
Be cautious. Harsh cleaning can damage a base-metal coin and reduce collector appeal. Identify it first from the legends and emblem, and if cleaning is needed keep it gentle and minimal.
