This 1986-D Lincoln cent displays an interesting mis-strike error, occurring during the striking process when the planchet wasn't properly positioned between the dies. The result is uneven metal flow and irregular strike pressure across the coin's surface. The obverse shows Lincoln's portrait with noticeable strike anomalies, while the reverse displays the Lincoln Memorial with characteristic mis-strike attributes. The Denver mint mark is clearly visible, and the date remains distinct. The copper-plated zinc composition appears vibrant with minimal circulation wear. Mis-strike errors like this provide collectors with a glimpse into the minting process and showcase the fascinating imperfections that occasionally escape quality control at the U.S. Mint. A great addition to any error coin collection, demonstrating one of the many ways coins can deviate from their intended production specifications.
