This 1 cent piece has kind of a shaddow image of lincolns bust on the reverse. The light refection at certian angles shows it well. Hard to get a photo of it. Is this what is meant by a strikethrough? I think photo #4 shows the best image.
I cannot see anything by the photos, sorry. But a struck through is when foreign matter is introduced into the coining chamber and impressed into the coin. Like grease, thread, wire, etc. As I found in an earlier thread I posted on a G.B. large cent, shadowing is caused by a high relief coin which transfers the image to the opposite side of the coin.
Most strike-thrus will affect one side of coin. Grease might be the cause here. If it was a strike-thru, whatever foreign matter were on both sides of planchet was not solid enough to prevent the dies from imparting the extruded features on the coin. Is any part of the affected areas incuse into surface of coin?
You're letting you imagination get the best of you. It's the way the light is reflecting off of the reverse. If I look hard enough, I can see Lincoln myself, especially his chin but it's just the light.
Common thing on later die strike lincoln cents. It is called "ghosting" or progressive indirect design transfer. Here is the error ref page on it: http://www.error-ref.com/progressive-indirect-design-transfer/
@alurid I see @Evan8 aswered the question I agree that what you have is PIDT - Progressive Indirect Design Transfer, common on Wheat Cents http://www.error-ref.com/progressive-indirect-design-transfer/
Thanks for the great info. Got better understanding of Strike-through. And the "ghosting" from Late Die State. After taking a look I have 6 or more of these, up to "57" . Better seen on BU's than Brown's. Fairly common on wheat cent so the link said. And it is the way the light reflects that let me see them. My proofs dont do it.
