Watch List notes:

Hadrian. 117-138 AD. Dupondius, 13.44g (5h). Rome, c. 125-8 AD. Obv: HADRIANVS - AVGVSTVS Bust radiate right, fold of cloak on front shoulder. Rx: COS above, III below, S C in field, Pegasus running right. BM 1331. Cohen 436 corr. (6 Fr.). RIC 658. Ex Berk 148, 29 March 2006, lot 411. Ex Leu 53, 21-22 October 1991, lot 244. Ex Leu 48, 10 May 1989, lot 344. Though traditionally assigned to the main Roman series, it seems clear from their reverse type that Hadrian's Pegasus dupondii must in fact be the largest denomination in his issue of orichalcum coins struck at Rome for circulation abroad, McAlee 544-552. As McAlee quite rightly comments, "The griffin on nos. 549 and 549A resembles Pegasus on BMCRE 1332 and 1334" (p. 224, note 19). In RPC 3759-60 the flying griffin on these two orichalcum asses meant for circulation abroad is actually mistakenly described as Pegasus.
