| 背面描述 | Two oil palm trees (Elaeis guineensis) depicted rising from a common ground line, their fronds rendered in fine detail and radiating symmetrically across the upper field. The large numeral 10 appears prominently to the left of the palms, with the denomination legend KOBO inscribed in the lower portion of the field. The design is contained within the twelve-sided dodecagonal flan with a plain edge. |

Nigeria switched from aluminum to copper-plated steel for this denomination in 1991 as part of a broader coinage reform driven by metal cost pressures and chronic shortages of small-denomination coins in circulation. The Kobo series had been undermined for years by the simple economics of hoarding — the metal value of earlier issues periodically approached face value, pulling coins out of the cash economy entirely.
