2013 P LSC Partial Lathe Lines Or Something Else

I thought lathe lines were only on the surfaces - not the devices! ?

And just noticed, on the 1st picture they aren't exactly circular nor concentric.

Found this on the internet:

Over the past several years there have been various reports by collectors of having found Lincoln cents with raised concentric lines (marks) on the obverse or reverse face of US coinage. First identified on 1996-D Lincoln cents, what was frequently observed were soft concentric lines that became stronger toward the perimeter of the coin, yet did not go into the devices.

So yours should not have lines in the devices! But who knows?

So lathe lines with die scratches in different directions? Looks like it.

i am going to say striations. Lathe lines should not run to the rim.

OK one last photo. All of these lines are in a just one narrow band around coin.

Without a doubt, those are definitely Lathe Lines that weren't polished off the die. Great find!

LEARNING TIME!

Do you really know what is meant by a "lathe line? Misconceptions such as have been stated in this thread show some dont. Lets consider the definition:




What this means is this is on the surface of a working die BEFORE the design is placed on the coin. The die face is BEVELED, that means it is slightly higher in the center than the outside. The milling lathe does this taper. It is then ground down and smoothed out before the design is "squeezed" int the die through the hubbing process. If any of these deep lines aren't removed, anywhere on the die face, they will be transferred to the coin design. Mostly seen on the die surface(field level) but sometimes in side the incused design(high points) also. It is seemingly less common for the central portion to retain any lathe lines since that is the high point of the die and is addressed heavily in the smoothing process. So it IS unusual to have the lines show up on the shield on the OP's coin, but more frequently around the outside.
