Can someone give me any information on this coin I had received. the value or the time period? thanks
Time period is early 4th century AD. I can not read the legend but Licinius I or Constantine I are possible.
I agree with Doug, and I don't think you're going to be able to get a more specific identification in this condition. The value of this coin will be pretty minimal, since this is a very common type, and it's not in good shape.
It is going to be Constantine I. SMK in ex. H in right field. Also I believe what is left of the bust on the obverse is laureated, not radiated. This should be your coin - http://wildwinds.com/coins/ric/constantine/_cyzicus_RIC_vII_003,H.jpg Cyzicus RIC VII 3,H coin value - sentimental - mike
