Anybody Else Finding These?

I have a couple of rolls of 2007 P Sac Dollars which I thought would grade out great but upon inspection found what appears to be a "burnished" area right above the "E" in e pluribus unum on the back side of the coins. Upon inspection the mark is a series of concave marks which appear to be faint wing impressions. In addition, some of the coins have a shaddow effect which runs from the lettering to the outside rim of the coin on the back- the fronts are all great. In addition, some even have marks which appear to be die cracks, also above the e pluribus unum and faint "wing" marks on the other side of the top wing. Like I said, I have two rolls- the first had this and I ordered a second in hopes of getting a "good" roll- I have sent 5 to be graded (of the better errors) but was just wondering what the rest of you are finding- are all of these P coins like this?
