The product is a circulated 1988-D Lincoln Memorial Penny from the Denver mint with a unique error on the obverse side known as a "strike through" error. This error occurs when a foreign object gets struck into the coin die, causing an indentation or mark on the coin during the minting process. As the coin is ungraded and uncertified, it adds to the rarity and uniqueness of this particular error coin. This 1988-D penny with a strike through error is a sought-after collectible among coin enthusiasts for its distinctive feature.
