Can anyone tell me what is wrong with this 2015 d penny?

It looks like something is going on underneath Lincoln's chin. Can anyone please tell me what it looks like?

In my opinion, those lines may be from die maintenance to cover up a possible die clash or is just to remove grime, grease and debris. They scrub the dies, some times a weee bit too much. Or, those lines could have been on the planchet before the strike. They look like the scratches are in the same direction, and affect the lower area and the design elements as well.
