Faustina I, AD 138-141. Roman AR denarius, 2.86 g, 18 mm. Rome, AD 141-147. Obv: DIVA AVG FAVSTINA, veiled and draped bust, right. Rev: CONSECRATIO, Eagle standing right, head left. Refs: RIC 387b; BMCRE 305 var.; Cohen 181; RCV --; CRE 95. There are a handful of other examples at acsearchinfo, struck with at least three reverse dies, but this particular reverse die is easy to identify because of the bizarrely-formed S in CONSECRATIO. Moreover, with use, the die became filled in the E, the R, and the T, such as on this reverse die match: Heidelberger Münzhandlung Herbert Grün, auction 52, lot 322, Nov. 13, 2009. Here are some examples struck earlier in the lifetime of the die before it became filled: CNG Mailbid sale 64, lot 1367, May 21, 2003. This is the CRE plate coin.
