I found another example of this coin with the type 3 hairstyle at NumisCorner's shop on V-Coins. It is not a die-match to mine. Because it exhibits less wear than mine, it better demonstrates the type 3 hairstyle.
Omg yay I get to join a Faustina Friday for the first time!! ^_^ Faustina Junior (AD 147-175/6). AR denarius (18mm, 3.29 gm, 7h). NGC Choice AU 5/5 - 5/5.Rome, AD 147-175. FAVSTINA-AVGVSTA, draped bust of Faustina Junior right, seen from front, wearing stephane, hair brushed in waves and tucked in small chignon at base of head / SAECVLI FELICIT, pulvinar facing with Commodus and Antoninus, as young children, seated facing each other. RIC III (Marcus Aurelius) 712.
Update! I can declare this one no longer "unique." I purchased this one at auction yesterday and am waiting for it to arrive in the mail. While it is quite corroded and with rough surfaces, beggars can't be choosers when it comes to rare varieties. Moreover, it was priced very reasonably. It is NOT a die-match to the Aureo & Calicó example illustrated in the OP. Faustina Jr, AD 147-175. Roman AR denarius, 3.12 g, 18.7 mm, 6 h. Rome, c. Autumn-late AD 151. Obv: FAVSTINA AVG ANTONINI AVG PII FIL, bare-headed and draped bust, right; Beckmann type 3 hairstyle. Rev: CONCORDIA standing facing, head right, gathering up skirt and holding cornucopiae. Refs: RIC 500b(6); BMCRE 1078-79; Cohen 44, Sear 4703; Strack 500; CRE 163. Notes: RIC erroneously describes the obverse legend as reading FAVSTINAE AVG ANTONINI AVG PII FIL; this is corrected by BMCRE 4.
Well, it's an old thread, and it is not Friday, but it is Faustina - and what I think is my first Beckmann Type 3 hairstyle. Even more exciting, I am pretty sure it is an obverse die match to the @Roman Collector OP sestertius. Yipee! Faustina II Æ Sestertius (mid 151-early 152 A.D.) Rome Mint [FAVST]INA AVG ANTONINI AV[G PII FIL], bare-headed and draped bust right / [VENVS] S C, Venus standing left, holding apple and scepter. RIC III Antoninus Pius 1387b; BMCRE 2168; Cohen 250.
