The coin is of Maximinus II issued as Caesar under the senior tetrarch Galerius.
The letter I in reverse field indicates his place as a "Jovian" alongside Galerius.

Issues of Maximinus II from western mints are nice as he was an 'eastern' emperor who issued primarily from Alexandria in Egypt. I recently picked one up from the London mint. The period of peace and harmony between the emperors was brief. Once they resumed normal 'frosty' relations they ceased issuing coinage on each other's behalf and commenced with active attempts to 'deify' each other.
