The first photo looks like a hit (maybe it's just the photo). The second photo looks legit. Do you have a pic of the rev?
The farther away I get the more legit it looks. Close up it looks like it could be a hit or contact that made the edge roll under somehow. Then again it looks like it still has a raised rim which points away from the PMD argument. I don't think it is a cud but it looks like one.
