AI Appraisal Estimate

This item is a 1974-D Lincoln Memorial Cent that has been modified with a secondary counterstamp. The base coin is a standard United States penny composed of 95% copper and 5% zinc/tin, measuring 19.05 mm in diameter. On the obverse, the original bust of Abraham Lincoln is visible, with the motto 'IN GOD WE TRUST' along the top rim and 'LIBERTY' to the left. The date '1974' and the mint mark 'D' (Denver) are located to the right. The defining feature of this specimen is a small, recessed counterstamp of John F. Kennedy's profile facing Lincoln, located in the field between Lincoln's head and the date. These countermarked coins were popular novelty items in the 1970s, often sold on cards highlighting coincidental similarities between the two presidents. The coin exhibits a natural copper-orange luster with some visible surface wear and minor scuffing typical of light circulation. There is a slight darkening or oxidation within the recesses of the Kennedy stamp and the main legends. The strike of the base coin is clear, while the counterstamp appears well-aligned and firmly impressed, though it is an after-market modification rather than a mint error.

I have carefully examined the provided images of this 1974-D Lincoln Memorial Cent featuring a Kennedy counterstamp. The base coin appears to be a genuine Denver-minted copper cent in About Uncirculated (AU) condition, retaining significant original luster with minor surface abrasions. The counterstamp itself is a classic aftermarket modification, well-executed with clear definition of Kennedy's profile. These coins were mass-produced by private firms in the early 1970s as novelty items to illustrate the 'Lincoln-Kennedy Coincidences.' From a numismatic standpoint, this is classified as damaged or modified currency; however, it holds value within the niche of exonumia and folk art. Market comparables for single uncertified specimens typically range from one to three dollars, often sold as 'pocket pieces' or on their original commemorative cards. The value is capped by the sheer volume produced during the bicentennial era. While the image confirms the physical characteristics of the stamp, a definitive authentication would require an in-person microscopic examination to ensure the punch wasn't applied recently to simulate vintage patina. To verify its specific origin, I would check for mechanical doubling on the strike and compare the punch dimensions to known 1970s manufacturer dies. As an image-based assessment, I cannot verify the metallic composition or the absence of chemical cleaning, but the natural oxidation visible in the recesses suggests an authentic period-made piece.
