Even though the coins of Faustina II are not dated, the different styles of her hair give an incredibly accurate date of their minting. Thanks to substantial die studies, the work of Beckman and @Roman Collector and his very informative Faustina Friday write-ups. Here is my latest acquisition Faustina II. AR Denarius. FAVSTINA AVG PII AVG FIL, draped bust right / CONCO-RDIA, Concordia seated left, holding flower and resting left arm on cornucopiae set on globe below seat. RIC 502a(3), RSC 54. Sear 4704 Beckman type 2 hairstyle, June of 152 CE – Autumn of 154 CE Feel free to post anything relevant
