@cogginstreasures11: The anomaly you are looking at inside the Lincoln Memorial columns is a die clash error. When the coining press cycles without a blank zinc-and-copper planchet between the dies, the front (obverse) and back (reverse) steel stamps smash directly into one another. This intense pressure transfers parts of the opposite designs onto each die.#coincollecting #pennyerrors #coinsworthmoney #checkyourchange #coins
