Æ21 - Trajan ΛΑΜΨΑΚΗΝωΝ

Lampsacus, positioned on the eastern shore of the Hellespont, had been a strategically vital port since the Archaic period and retained enough civic prestige under Roman administration to strike its own bronze coinage well into the imperial era. Its inclusion in the Conventus of Adramyteum placed it under the judicial circuit of a regional assize center rather than the more prominent Pergamene conventus — a geographic assignment that shapes the relatively thin documentary record for its imperial-period bronzes.

The reference III#1550A suggests classification within a supplementary or variant grouping, indicating this type was catalogued after the primary sequence was established.
