I don't know how I done it but I made a mistake by misreading the emperor. It's supposed to be Maximinus II, not Maximianus. I wish someone would have said something. lol Here is the right coin.

Maximinus II AE Quarter Follis. 305-306 AD. MAXIMINVS NOB C, laureate head right / GENIO POPVLI ROMANI, Genius standing left, naked except for modius on head & chlamis over shoulder, holding patera & cornucopiae, SIS in ex. RIC Siscia 171B
