What are these lines in my 1930 Buffalo Nickel

Looks like heavy die file lines, what else could have caused it? Not a great coin, but I am learning and this caught my eye.

Behind E Pluribus Unum and ERICA



Behind FIVE CENT and below Buffalo

It could be die erosion on a heavily worn coin. Could you post photos of the whole coin?

what Chris said

 

I think it's from die polishing.

 

It is pretty worn, here is the whole coin.

 

Probably die polishing. Interesting - both raised and recessed lines. Since raised and the recessed lines are from wear (not lamination) it seems a worn out die polished affected coin.

Great info, thaks all.

 

Which lowers the value and grade of this very flawed coin. Right, GD?

 

Flawed planchet.

Die wear and the subsequent flow lines tend to be radial from the center of the coin. These lines are all linear like you would see from roller marks.

 

Ok, that is a new term "roller marks". Is there a glossary somewhere on this forum?

 

This is what it appears to be.

 

I think it's reference to the transport mechanism that moves the sheet of metal during the blank-cutting operation.

Those lines look like where the die was worked on, they tried to stretch out its life.

 

I thought they were caused when rolling the blanks to the correct thickness.

 

Yeah, this is more plausible.

Rolling the strip to the proper thickness. The steel rollers can also become worn and develop lines or ridges that go around the roller. These ridges can impress marks into the surface of the strip running along the length of the strip.
