A newly discovered type for an antoninianus coin of Postumus leads a Sept. 15 auction by Paul-Francis Jacquier.
The unique and previously unknown type of the antoninianus of Postumus is notable for its unique bust. The bust featured on the obverse is cuirassed (armored) but devoid of drapery, which distinguishes it from the tens of thousands of others known from coin hoards, public and private collections, and auction catalog illustrations. During the reign of Postumus, antoniniani generally showed a ruler's bust as cuirassed and draped with a military commander's cloak.
