Depeyrot 73/2. DOC 313-8 (different officina). RIC X 202. Well-struck and lustrous. Extremely fine.

From a European collection.
The only difference between this coin and with those of the same issue struck during the joint reign with his father, Arcadius, (as RIC X 31) is the absence of the third G in the reverse inscription, the lack of which indicates that it was struck after the death of Arcadius in 408.
