I like attractive, affordable Emperors and this one looks pretty decent to me as far as the patina and such goes.
Seller incorrectly attributed it as Maximianus. (Not that I blame him or her with these particular coins!)

Gaius Galerius Valerius Maximianus (Galerius) reigned from 293-311, at one point sharing power with five other "emperors." He is today remembered for his successful campaigns against the Sassanid Empire in Mesopotamia, but perhaps more so for his role in Diocletian's persecution of Christians and the civil war that raged as the emperors fought for control.
After being stricken by terminal sickness and disease in late spring 311 AD, his subsequent edict of tolerance, repentance and a fervent request for prayers couldn't forestall his death a week later.
