This posthumous coin from Cyzicus is interesting because it lists two Emperors in the obverse inscription -- Galerius (DIVO MAXIMIANO) and Maximinus II (MAXIMINVS AVG FIL)
The second interesting thing is the use of AVG FIL (son of Augustus), This was a title given to Maximinus II and Constantine I when they were passed over for promotion to Caesar. Both rejected the title, but here Maximinus is using it. Galerius was his uncle, but adopted him and now Maximinus is reminding everyone that he is actually the son of an Augustus.
it also looks like it may be from workshop A, which is not in RIC.
OBV: DIVO MAXIMIANO MAXIMINVS AVG FIL
