The image you posted looks like a seam. Does it look that way to you? That can only be caused by a casting. With very very little exception (some of the very first Roman Republic coins), Ancient Roman coins were struck not cast. Now that I look at the original images you posted, it looks like there may be some casting bubble holes as well. These would appear as round holes on the surface of the coin. The images are too small for me to see clearly. But if you can see round holes, that is another indicator.
IMHO, even if your coin is not cast but genuine, the value of it would be fairly low anyways for a couple of reasons. First, and foremost, it has been holed. This brings down the value considerably especially since it goes through the head of Venus. Secondly, the coin has very soft features which could be an indication it is either badly worn or again a cast. I'm not a coin snob, but even if I were in the market for a Faustina II coin, I don't think I would give this coin a second look. There are too many better ones on the market at affordable prices. Sorry for the blunt assessment.
