Hello coin experts. I am new to posting & collecting. I found a 2012 P dime that to me has a lot going on. Definitely has a huge bulge on both sides of coin yet its on opposite sides of the coin left & right.This I cannot identify due to me being green. I could really use some help identifying the bulge not to mention I see numbers on both sides, letters, holes & marks. I don't know what to think of this bad boy. Would someone in the forum mind educating me on what you see? Thank you very much in advance.
