As a growing child, even as young as six years of age, I remember that at school and in local shops, there were items sold for five kobo (5k), twenty kobo (20k), twenty-five kobo (25k), one naira (N1), three naira (N3), two naira ten kobo (N2.10k) and so on. It was a common sight to see both the old and the young in possession of coins and naira notes.
