Faustina the Younger was the youngest child of Emperor Antoninus Pius and Faustina the Elder. She solidified her position by marrying Marcus Aurelius, who was adopted by Emperor Antoninus Pius and eventually succeeded him. Emperor Marcus Aurelius granted Faustina the Younger the title of Augusta, and she bore fourteen children in the service of the emperor. Faustina the Younger was held in high esteem by the soldiers as Augusta and honored as Mater Castrorum. She received divine honors after her death. This Sestertius coin features a side-profile portrait of Faustina wearing a diadem on its obverse side, with the inscription "FAVSTINA AVGVSTA" struck onto it. The reverse side of the coin depicts Fecunditas, the goddess of fertility holding a child and a scepter, along with her name "[FECUND]DITAS" inscribed on it.

Annia Galeria Faustina was born about 127 A.D., daughter of Emperor Antoninus Pius and Faustina the Elder. Hadian engaged her to Lucius Verus; but when Pius became Augustus on July 10, 138, he broke off the union and engaged her to Marcus Aurelius. Due to her youthful age, the wedding was postponed several years until 145. Her first of perhaps thirteen children (including future Emperor Commodus) was born in November of 147, when she received the title of Augusta. She accompanied Aurelius on some campaigns and trips, and was with him when she died at Halala in Cappadocia in late 175. She was soon deified, and Halala was re-founded as Faustinopolis.
