Help identifying ancient coin

[Deleted User]

I know I have already posted a few ancient coins but I have several others but I am trying to clean them up a little for identifying what they are.
Can anyone help me identify this one?

You can just read the obv legend:
IMP CONSTANTINUS PF AVG
although there seems to be a typo and it looks more like CONSTMNTINUS .
Anyway, Constantine I or II; this is a fairly common type of coin.
