The aesthetics really matter with these coins, the Ancient Greek coins held to a fairly high standard of art and collectors often see the nicer Greek coins as ancient art objects are much as coins. The portrait of Athena and the stylization of the owl on the Athenian tetradrachma are part of why people like them, nicely struck examples with centered art and no wear are the most expensive. The ancient tests didn't just chop into the edges like the article mentioned, but cut gashes into Athena's face, into the owl, and often both with several severe gashes marring the coin, significantly reducing their value as an ancient art object.
