In 1973, coins were introduced in denominations of {{frac|1|2}}, 1, 5, 10 and 25 kobo, with the {{frac|1|2}} and 1 kobo in bronze and the higher denominations in cupro-nickel. The {{frac|1|2}} kobo coins were minted only that year. In 1991, smaller 1, 10 and 25 kobo coins were issued in copper-plated-steel, along with nickel-plated-steel 50 kobo and ₦1. On 28 February 2007, new coins were issued in denominations of 50 kobo, ₦1 and ₦2, with the ₦1 and ₦2 bimetallic. Some Nigerians expressed concerns over the usability of the ₦2 coin.<ref>{{cite news | title=Nigeria: Nigeria's New Notes And Coins | url=http://allafrica.com/stories/200702220103.html | publisher=This Day | date=2007-02-21 | access-date=2007-02-26 }}</ref> The deadline for exchanging the old currency was set at 31 May 2007.<ref>{{cite news | title=Nigeria: New Currency - Two Per Cent of Withdrawals to Be in Coins - CBN | url=http://allafrica.com/stories/200702210778.html | publisher=Vanguard | date=2007-02-21 | access-date=2007-02-26 }}</ref> The central bank stated that the {{frac|1|2}} to 25 kobo coins were withdrawn from circulation with effect from 28 February 2007.<ref>{{Cite web |title=Central Bank of Nigeria:: Currency Gallery |url=https://www.cbn.gov.ng/Currency/gallery.asp |access-date=2022-12-20 |website=www.cbn.gov.ng}}</ref>
