1992 D Cent - Bubbling?

Here is a 1992-D cent I found coin roll hunting. There is a crater right where the mint mark is. It also looks a little bubbled up around the perimeter of the cratered area. Also, there is another slightly bubbled area at the left base of the "2" that is opening up ever so slightly. If this is an error, and not just damage, I am not familiar with it. I need a little help. Can someone explain? Thank you.
