Watch List notes:

Faustina II, Wife of Marcus Aurelius. Aureus, 7.23g (12h). Rome, c. 148 AD. Obv: FAVSTINAE AVG - PII AVG FIL Bust draped right wearing stephane, band of pearls, and Strack's coiffure a. Rx: VE - NVS Venus standing left holding apple and rudder, dolphin coiled around rudder. Bust variety of Strack 495, BMC 1063, Cohen 260 (40 Fr.), RIC 517b, and Calicó 2097c. Ex Berk 198, 7 July 2016, lot 9. Ex Heritage ANA Sale 3033, 8 August 2014, lot 23085 (Jonathan K. Kern Collection; there in NGC capsule with grade "AU 5/5 - 4/5, Fine Style"). Apparently very rare with portrait wearing stephane. This variety is not in the standard references, since the specimen cited by RIC 517b actually has no stephane. CoinArchives Pro includes only two examples of this aureus with stephane: our actual coin, and one other from the same obverse die.
