Note 1: This coin was bought as an unattributed Roman provincial coin, with a note saying "Trajan?". That much was certain, made clear by those parts of the obverse legend which were clearly visible. The full attribution was pinned down by Markus on the Forum Classical Numismatics Discussion Board, including a note that this coin appears to be a double die match with the Lindgren specimen. Curtis Clay says: "According to Icard, Heracleia Pontica is the ONLY city to use this Doric form MATPOΠOΛЄITAN rather than the Attic MHTPOΠOΛЄITΩN on its coins."

Note 2: The same Roma (or Athena) can be seen on these two coins: semi-autonomous, Thyateira; semi-autonomous, Elaea. Several other semi-autonomous coins from Asia have the same type.
