Obverse reads D N CONSTAN-TIVS P F AVG. The reverse reads GLOR-IA EXERC-TIVS and the mint mark is SMK(?) which puts it from Cyzicus. I can not make out the workshop symbol so I can not nail down a particular RIC # for you. Perhaps another set of eyes can make it out. This coin was minted between 337 and 340 A.D.
EDIT: This coin is actually a Constantius II, not Constantine II. Hope this helps!
