Welcome! There might be a touch of split plate doubling as well. I can't quite see. If there is notching, you'd definitely need much closer photos.

Thanks shane when I get better pics I will upload them here so you can see.

I do not see notching, only die wear/fatigue manifesting itself into a type of shadow doubling. There may be split plating as well.

Those shadow lines always appears as notches in letter its looks like weak splits inside the litters

You have no idea what notching is. What ever you're seeing is something else related to die wear or split plating and on most Lincoln cents past 1982.

Here are my diagrams (using an overlay) showing how during a multi hub process the misalignment of the serifs, or other small details on the ends of a device, cause NOTCHED coroners and split serifs.
