Firstly,

I am sorry but can tell little to nothing with these pics. Need clear, front on pics, not angled and clear full coin shots. A nice clear shot of the mm would be good along with clear shots of the neck area. I cannot tell from these pics if what you are referring to is damage to the coin, toning or an actual anomaly from the die it was struck from.
