Achaiion or Achaeïum or Achaeum (Ancient Greek: Ἀχαίιον) was a town in the Tenedian Peraia of the ancient Troad.[1][2] The legend AX (ACH) which some bronze coins found in this region bear is thought to refer to Ach(aiion) by Louis Robert,[3] but others attribute the coins to Achilleion.[4]
Its site is located near Hantepe, Asiatic Turkey.[5][6]

: CS1 maint: location missing publisher (link) objects that whereas Achilleion is twice attested as a polis and therefore capable of minting coins (Herodotus 5.94.2, Stephanus of Byzantium s.v. Σίγειον) Achaiion never had political autonomy and always belonged to the Tenedian Peraia.
