The mark across the pillars is a bag mark. The two marks in the window and doorway are made from a feeder finger. I don't see the DDR.
I'm not so sure about Feeder Finger on this. I found the same coin and it very much looks like a doubled die. I can't be certain, so I say this humbly. This is the usual place for new doubled dies and also inside the door. And the curve, slight as it may be, is not consistent with most straight line feeder marks. I don't have enough nickels to send to Brian Ribar to make it worth the effort so have not been able to ID properly. I also have not seen any listed yet.
Too bad about the damage but I think you have a DDR as I found the same one and I believe it is consistent with other DDR's in the same area. I stand to eat my hat if I'm wrong and P&G is correct but I have not seen any listed yet so I can't be 100% positive.
Feeder finger damage would be copied from one strike to another, or until the die gets polished. The lines are parallel and do not fit the same angles as what they are imitating. Otherwise I would probably say DDR.
