This is one of my best Roman coins. It's a fairly rare double centenionalis of the emperor Magnentius A.D. 350-353. The reverse of the coin shows a large christogram. The flan it was struck on was a little ragged, but over all it's in good shape.
Very Nice condition, I can't quite make out the mint, do you know what it is?
[/quote Think the mint for this coin should be AMB for Ambianum, it certainly though is not that. Looks more like TRC ?.
