If you want to get the best responses, crop, post full image and mention what you think might be the error...
penny looks normal to me the nickel thought might be broad strike error or just circulation Wait for more opinions.
The Lincoln cent piece has some damage on Liberty probably from an old candy or gum machine or coin counter that used a prong arm. The Jefferson shows a lot of die deteriorated that pushes the details towards the rim. The rim looks like something/someone tried to grind it for some reason. No extra value visible. Jim
