This coin above is one of the very few that I believe is ACTUALLY from Myos. The vast majority of coins attributed to Myos are, in my opinion, from Myndos.
An interesting facet about Myos was the fact that the entire city disappeared due to silting. While originally it was a coastal city, eventually it wound up to be inland.
The reason I believe the coin above is from Myos is its similarity to the types of Priene, which was another Ionian city nearby that spoke the same dialect.
The Battle of Lade is fought between the Ionians under Dionysos of Phokaia and the Persians. Chios has the largest contingent, followed by Miletos, Lesbos (probably Mytilene), Samos, Teos, Priene, Erythrai, Myos, and Phokaia. Most fled during the battle, but the Chians put up a bold resistance before defeat.
