1975 Lincoln Memorial Cent (Philadelphia Mint)

This is a United States one-cent coin, commonly known as a Lincoln Penny, dated 1975. The coin features the right-facing profile of Abraham Lincoln on the obverse, designed by Victor David Brenner. The lack of a mint mark below the date indicates it was struck at the Philadelphia Mint. Composed of 95% copper and 5% zinc/tin, it exhibits a heavily circulated and degraded state. The surfaces show significant environmental damage, including dark brown oxidation and patches of green verdigris, particularly near the lettering of 'LIBERTY'. There are numerous surface abrasions, scratches, and nicks across the bust and fields. The rim is worn and shows minor indentations. The strike appears standard for the era, but the extreme wear has flattened the higher points of Lincoln's hair and jawline. The coin lacks original mint luster and shows signs of long-term exposure to moisture or corrosive elements, resulting in a pitted texture across several areas of the obverse face.

I have conducted a visual inspection of this 1975 Lincoln Memorial Cent. Based on the provided imagery, the specimen is authentic but remains in a highly degraded state. The coin is struck in the standard 1975 composition (95% copper), and the lack of a mint mark confirms its Philadelphia origin. However, the condition is poor; the presence of heavy oxidation and green verdigris indicates advanced environmental damage that has likely caused permanent pitting to the metal surfaces. Such 'cull' or 'environmental damage' designations significantly impair numismatic value. From a market perspective, the 1975 Philadelphia cent is an exceedingly common issue with a mintage exceeding 4.6 billion. It is not considered rare, and high-grade specimens (MS-65 or higher) are readily available for a few dollars. Because this specific coin lacks mint luster and shows significant wear and corrosion, it possesses no premium value to collectors beyond its base copper bullion content (melt value), which currently sits at approximately two to three times its face value. Authenticity is determined here by the correct profile, letter spacing, and date font, though image-based analysis has limitations. A definitive appraisal would require weighing the coin to the decimal milligram to ensure no off-metal planchet error exists and a microscopic inspection to confirm the verdigris hasn't masked underlying mechanical damage. Without physical inspection, I cannot rule out 'zinc rot' if the core were compromised, though the 1975 date suggests a solid copper alloy. No provenance was provided, which is standard for low-value circulation finds.
