Look like there is a good possibility those are trails. Correct me if I'm wrong guys, but I'm pretty sure that with most forms of die deterioration, the die flow lines run radial to the rim. These all appear to run the same direction (350 degrees +\-).
Thanks for stopping by everybody, theres 2 different kinds known for the 1996-D, but none for Philadelphia, this coin has some very strong trail dies, I'll post the link to the 1996-D http://www.traildies.com/1990-1999d_25_cent_obverse_dies_with_trails/
