Watch List notes:

Marciana. ; Marciana; Thyatira, Lydia, Sister of Trajan, died 29 August 112 AD, AE 14.5-16, 2.99g. RPC-1829A. Obv: MAPKIA - [CEB]ACTH Bust draped r. Rx: TVA / TIPH / NON in three lines within laurel wreath. Unique and the first attested coin of Trajan's sister Marciana at Thyatira; not in the printed RPC III, but RPC online-1829A cites and illustrates our specimen, from source eBay, 2019. Not unexpected, for Thyatira also struck coins of the same small size for the two other Augustae of Trajan's reign, that is Plotina, his wife, and Matidia, Marciana's daughter; and our coin of Marciana uses the same reverse type, city name in wreath, as one of Plotina's coins at Thyatira, RPC-1829. The abbreviation of Marciana's name to just MAPKIA occurs also on her coins at Sardes, RPC-2398.This coin is extremely rare and the only one in existence according to RPC where it is the plate coin and the only specimen listed.
