Watch List notes:

Hostilian as Augustus. 251 AD. Dupondius, 12.89g (12h). Rome, . Obv: IMP CAE C VAL HOS MES QVINTVS AVG Bust radiate, draped, cuirassed right. Rx: ROMAE AETERNAE around, S C in exergue, Roma seated left above shield, holding Victory and shield. Berk 94, 1997, lot 724 (this coin); otherwise apparently unpublished. Ex Berk 94, 16 January 1997, lot 724. A very rare denomination for Hostilian as Augustus, apparently unique with this reverse type. RIC 223a-b and Cohen 48-9 report only the sestertius and As of this type, both also very rare, and Richard Beale's website on the coinage of 249-253 AD knows the corresponding dupondius in only one specimen, namely our coin.
