What Cause These Marks On Cents

Hi
#1 possible die clash. If you look st the corresponding area on the other side it should line up with Lincoln'c neck

#2,3 Appears to be die wear or overpolishing

the last one I/m not sure

Ziggy

#1 Die clash mark from the obverse die.
#2 & 3 Excessive die cleaning, thinning of the outside edge of the die. Looks like the die is bending, but the filed is being worn so that the field and the letters appear to blend together.
#5 I'm not sure what you are pointing at, but will guess. The die cracks on the columns happen a lot. The crack from top to bottom. On column # 12, it is very common. Many will use that as a marker, but that is not an accurate area as a large percentage have a die crack on that column. If there is something I missed, others will help.
