My two cents: Penny is typically derived from "Penelope," who in Greek mythology was the wife of Odysseus who remained faithful to him and refused to take any of the suitors as her husband after Odysseus "died". "Pēnelopē (Πηνελόπη) is usually understood to combine the Greek word pēnē (πήνη), "weft", and ōps (ὤψ), "face", which is considered the most appropriate for a cunning weaver whose motivation is hard to decipher."
