I noticed like a jagged line of extra copper on this cent just wondering what it is and if it would be an error? I think it is I'm just not sure what never seen it before.
It's called a Lamination Error. I want to share this webpage with you http://www.error-ref.com/lamination-cracks/
Oh ok well thank you, it goes all the way up into the back of Lincolns head, getting more and more faint. Are these worth more than the face value and worth keeping?
They are common errors on Copper Cents. They have to be major laminations in order to have a good premium. I have purchased similar to yours for like $2 - $4 bucks
Here is a thread for a Major Lamination I had certified https://www.cointalk.com/threads/1c-1960-d-large-date-obverse-reverse-laminations-ngc-04.292084/
looks more like a small plating issue. You can see plating blisters in different areas, especially on the bridge of the nose.
Yeah i see all the blistering but that on the edge goes over the L and onto the rim southwest of the L and it just doesn't seem like a bubble or blister.
Could be a 'rim burr', where a sliver of metal from the rim of the planchet was folded onto the planchet when it was struck. Doesn't look like most Rim Burrs, so it's possible that it's a minor plating issue, but I wouldn't call it a plating bubble. More of a striking anomaly than anything else, imo.
