Poll Question
HI everyone! Curious what yall think? 2005 Lincoln cent with odd lines pictures below. If you zoom in you'll see the lines front and back affecting fields and devices except for the deepest of the strike. Let me know what you think! Thanks!! P.S. I have no idea what it actually is. Lol

I believe it's just Linear Plating Bubbles.

Something that cause a distortion on the fields can be a slight amount of liquid like water/oil that prevents the strike from removing these planchet lines. Note on your coin two areas are affected? So it maybe an issue with something of the fields of the die. But these lines must be pretty strong on the planchet. Note how the steps and the shallow designs are also affected preventing the strike on that area. I saw this happen on an off center coin. The lines were on the planchet and even after the strike, they were still visible:  But not a premium for the coin. Just a striking event. |

So the lines are on the planchet before the strike, good to know coop.  |

I agree Tunnioc! Coop pretty much always knows his stuff!

Yeah coop what gets me on this coin though is that they are visible literally everywhere except the highest points. It's on Lincolns check and neck, his jacket, on the reverse in the lettering and the steps, even where the picture doesn't show much it's there to the eye and light is washing it out in the pictures. I didn't know what to make of it or what to call it but I came down to those two options. I think if it were linear plate bubbles it wouldn't be literally everywhere and so uniform in size.. but I don't know that for sure and on the other hand, no clue what exactly to call it. I feel like it must be pre-strike and the strike can't completely obliterate it for some reason, but it's a really decent strike overall and I think it should have or the stike should be weaker. Perplexing. I like your explanation though.
As far as value. Meh it don't matter to me. Its been tucked away since 2005 until I dug though coin boxes and remembered it's there and today was that day. Lol. just never knew what was going on really which is why I hung on to it. Probably deserving of a nice 2x2 for a reference piece. Maybe in 30 years people will come to value them. lol
So it would possibly be rolling lines if I had to name the issue?

Could the lines be on the blank before plating? Die abrasion,like to remove a die clash? John1  ( I'm no pro, it's just my humble opinion )

These are roller lines left on the coin metal sheet by the rolling mill before the blanks were punched.

Will Brooks has written an article on these and he calls them (if I recall correctly) striations which are caused by roller lines as Coop and Stoneman have stated.
The striking pressure as well as the depth of the design can affect how much/many are visible on a struck coin.
John1, they are on there as the sheets are rolled out, so yes, before the copper plating.

So blank/planchet issue not a plating issue. John1 ( I'm no pro, it's just my humble opinion )

I see these on a lot of LC's. This one the lines are more pronounced than usual.

Man I'm looking into all this now and learning quite a bit as well, thanks for pointing me in a direction. Really glad I posed this as a poll to get people to look at it a bit deeper. LOL. You guys truly are a wealth of information! You be surprised how hard it is to look this up without knowing what to call it.
