Watch List notes:

Ionia, Ephesus. Marciana(?). Augusta, ca. A.D. 105-112/4. Æ 17 (17 mm, 3.48 g, 6 h). Very rare. Diademed and draped bust right / Statue of Artemis Ephesis facing. Seemingly unpublished. Fair, gray patina. 

Ex Alex G. Malloy Collection. 

Since the legend is entirely worn, the attribution to Marciana is conjectural and is based solely on the style of the portrait. It could be a portrait of either Matidia or, less likely, Sabina as well, although it more closely resembles the imperial portraits of Marciana.
