"Trophy:
Throughout the history of the Nations Cup, three different trophies have been awarded to the winners of the competition. The original trophy, made of silver, was the "Abdelaziz Abdallah Salem Trophy", which was named after the first CAF president, the Egyptian Abdelaziz Abdallah Salem. As the first winner of three Nations Cup tournaments, Ghana obtained the right to permanently hold the trophy in 1978.

The second trophy was awarded from 1980 to 2000, and it was named "Trophy of African Unity" or "African Unity Cup". It was given by the Supreme Council for Sports in Africa to the CAF prior to the 1980 tournament and it was a cylindrical piece with the Olympic rings over a map of the continent engraved on it. It sat on a squared base and had stylized triangular handles. Cameroon won the Unity Cup indefinitely after they became three-time champions in 2000.

In 2001, the third trophy was revealed, a gold-plated cup designed and made in Italy. Cameroon, permanent holders of the previous trophy, were the first nation to be awarded the new trophy after they won the 2002 edition."
