Post your Orbianas, comments, or anything you feel is relevant! Although I purchased this coin in 2011, I thought I'd revisit it today as I have been recently reorganizing my Severan collection by BMC numbers, rather than by RIC numbers because so many of the RIC listings are dubious (see here and here, for examples). Orbiana, wife of Severus Alexander, Augusta AD 225-227. Roman orichalcum sestertius, 20.02 g, 28.6 mm, 12 h. Rome, special marriage issue, AD 225. Obv: SALL BARBIA ORBIANA AVG, diademed and draped bust, right. Rev: CONCORDIA AVGVSTORVM S C, Severus Alexander, togate, standing right, holding scroll in left hand and clasping right hands with Orbiana, veiled and draped, standing left. Refs: RIC 657; BMCRE 301; Cohen 6; RCV 8194; Banti 3. If you were to go by RIC, you'd think there are no variants of RIC 657: However, when one consults BMCRE6, there are two variants noted, nos. 299 and 300, where Severus Alexander does not hold a scroll in his hand on the reverse, and no. 301, where he does. So, I thought I'd look at the plate coin, because it was supposedly the same variant as mine and as described in RIC -- with Alexander holding a scroll. I became confused, because the emperor is not holding a scroll. I thought they must have accidentally illustrated 299 or 300 instead by mistake. So I searched the British Museum collection online and found the coin illustrated is the obverse of 301 ... ... combined with the reverse of 300! OOOPS! In addition, here are the two reverse variants in high grade as seen on examples in the Münzkabinett Berlin (OCRE online).
