    Error Planchet | Zinc Planchett but what are the lines?

    This coin has no copper except for the west edge. Does anyone know what the lines are on the reverse? They are raised, not filled with air, do not flatted when pressed on. They are not die cracks or scratches. Welcome everyones opinions or ideas.
    Thank you.

    Since there is no copper I would believe that the lines are from the die ejection system or from the die itself... Not sure though... Bob and the other pros would know!!!

        This is one of the give aways that this coin has been chemically stripped of its copper plating.

        A true zinc planchet strike does not show lines like this. A zinc planchet struck Lincoln cent should weigh slightly less than a plated cent and the surface should be free of raised areas, especially striated lines are dots forming striated lines. In other words, it should appear exactly like a copper plated cent, except without the copper.

        BJ Neff

        Let me also add that these lines could be mistaken for die scratches; however, if you look at the individual lines, there is no strength differential between the intensity of the line when it is in the field or when it passes over a design element. This does not occur with a die scratch. When a die scratch passes over a design element, it tends to weaken considerably since it must reach into the recess of that design element on the working die.

          I personally have seen several fakes and currently have one genuine fully unplated and one partially unplated. As BJ stated, it looks stripped.

            I agree. I suspected it was stripped when the copper was only on part of the edge. What I was wanting to know is about the lines on the reverse. They do not resemble the ejection fingers and they are not cracks. Thanks everyone for helping.
