Gallienus, Æ double sestertius medallion, (9.48g) 
GENIVS P R Radiate head of Gallienus as the Genius of the Roman People. 
INT VRB above and below large SC, all within wreath. 

Rare type.

Generally attributed to the Interregnum between the death of Aurelian and
the ascension of Tacitus. Vagi logically argues this coin is an issue very
late in the reign of Gallienus. His arguments includes the use of the
facial features of Gallienus, visible on this example.

MIR 36, 702h; Yonge A.39 (dies Q/q); Hunter 1 (Interregnum); 
Cohen 334; Vagi 2425.
