I have been trying to hunt down the correct attribution to this one and am having a heck of a time. I Think that it is Heraclea Ric Vlll And that is just by the portrait. The reverse is too weak and doesn't have the MM. Any Ideas? Commemorative issue of Constantine The Great. 347 to 340. Obv. Veiled Constantine to the right, Rev. Constantine riding a Quadriga reaching for the "Hand of God" Commemorating Constantine's conversion to Christianity and giving the people of the Roman Empire religious freedom!
