The most AP per gold would come from an Elixir of Brilliance, but obviously that only lasts 4 minutes. The cheapest permanent AP comes from Needlessly Large Rod.

For Champions with mana, the maximum ability power build is 5 Archangel's Staff's, one Rabadon's Deathcap and one Elixir of Brilliance. For Champions without mana, that would be 4 Zhonya's Hourglasses, one Mejai's Soulstealer (with at least 13 stacks), one Rabadon's Deathcap and one Elixir of Brilliance.
