Uncirculated Penny Appraisal

1989-D Lincoln Memorial Cent

This is a United States one-cent coin, commonly referred to as a penny, dated 1989 with a 'D' mint mark indicating it was struck at the Denver Mint. The coin is composed of a copper-plated zinc core (97.5% zinc, 2.5% copper). The obverse features the profile of Abraham Lincoln designed by Victor David Brenner, as evidenced by the faint bust silhouette. The inscriptions 'LIBERTY' and the date '1989' with the mint mark 'D' are visible despite significant surface degradation. The coin exhibits severe environmental damage and corrosion, characterized by a thick, crusty layer of verdigris (green patina) and dark oxidation covering much of the obverse. There is evidence of zinc rot, where the thin copper plating has been compromised, allowing the inner zinc core to react with the atmosphere. This has resulted in a bubbling, pitted surface texture that obscures finer details such as Lincoln's eye and hair. The rim shows minor nicks but maintains its circular integrity. Due to the extensive corrosive damage and commonality of the date, this specimen lacks numismatic premium and is considered to be in 'cull' condition, possessing only face value or nominal copper scrap value.
