Roman 1/2 centenionalis c.330AD

Roman coin experts! I could use some help with this identification.
  The best I can tell is that this coin is a 1/2 centenionalis, probably from the Heraclea mint, around 330 AD. The obverse inscription is "VRBS ROMA" and shows a helmeted man facing left. I note that the helmet has two tassles, one ending pointing up, the other down. Similar coins have the tassles going in different directions. On the reverse is a she-wolf suckling Romulus and Remus. There are two stars over the wolf. There is a line under the wolf and below that are the letters "SMH (epsilon)", as best I can tell.  I entered it as a new coin, along with the pictures I attached here. I do not have a KM# for it, and no other information.

If anyone has more info, I'd be grateful for any help you can provide.  Thanks, Raider in Delaware, USA.

Hi

No expert, but according to wildwinds, it is a commemorative coin with the bust of Roma.
You're spot on with the date. Constantine the Great?
Nice coin.

Thanks, Trunk,

There is a small local flea market here in Dover, Delaware where I have had the most amazing luck finding off the wall coins and artifacts.  For example, a friend paid 50 cents for a box of odd junk and found in it a walking stick made of a hickory branch, where each leaf bud had been drilled out and filled with silver, and a letter stamped on each one.  Reading from the top down it spelled "A-N-D-R-?-W-J-A-C-K-S-O-N".  President Jackson's nickname was "Old Hickory", and an identical cane (or the same one?) is seen in the portrait on the $20 bill.  I paid $7 for a copy of the New York Herald from April 18, 1865, that reported the death of Pres. Lincoln.  I watched a man buy an old dictionary in a pile of old books (the whole pile for 50 cents) in which he found 20 old $1 bills with bright green and red ink, called "funny money", circa 1930, in mint condition.  And now I have a coin from the Roman Empire in the year 330 A.D.  A curious place.

It's RIC VII 114. Time of Constantine I. AD 330-337
