what happened to these coins?-- batteries went dead on my camera. will take a little while for the rest-- ok, they are all here
Various types of after-mint damage. #1 was probably squeezed by something with a straight edge. #2 was probably acid washed. #3 my guess is a pair of pliers - perhaps either squeezed in a vice or hit with a hammer. #s 4-5 look like something was placed on top of them and then hit with a hammer.
#1 looks like it was possibly struck through something. Is the rev normal? #2 looks like a dryer coin (stuck in the fins of a commercial dryer for awhile). #3 looks like a lamination error. #4 & #5 are die cracks, some call them "cracked skull" Lincolns and are pretty common in the 40's-50's dates cents. All of them look legit to me and not post mint damage, but I could be wrong, have been before and will be again..lol.
