1976 Lincoln Penny-Lines?

Those are called rolling lines of the stock material seen on the copper planchets more on the 1970's/80's cents. These are the rolling lines on the metal that show up after the BU look disappears from the coins. They are only surface lines. They eventually wear off the coin on the higher locations first, then then the fields. Not to be confused with woody coins. They are only surface. On the woody coins the poor mixture affects the whole planchet all the way through. Even on worn coins if the woody look was there from day one, they will still show on worn examples.




These rolling lines can be seen even on the zinc cents as well. Even the striking doesn't remove them:

So when the BU goes away expect to see these slowly wear off these coins as well.

Always nice to see a visual view. Words get lost in usage, seeing is understanding for me.

Are my eyes deceiving me, or can I still see the lines on Lincoln's profile - this coin does show quite a bit of wear..
