Lincoln Cent (Penny)

The obverse features the bust of Abraham Lincoln facing right, with 'IN GOD WE TRUST' above, 'LIBERTY' to his left, and the date '1964' to his right. The coin appears to be set in a bezel or altered for use as jewelry. The mint mark, if present, is below the date.

The Lincoln Cent, first issued in 1909 to commemorate the 100th anniversary of Abraham Lincoln's birth, is one of the longest-running coin series in US history. The 1964 Lincoln cent was the last year before the composition changed due to rising copper prices, making it notable as one of the last pennies composed almost entirely of copper. Coins from this year are generally common.

In its current condition, as a common date coin that has been altered (holed/mounted for jewelry), its numismatic value is significantly diminished. Its value is likely no more than face value to a few cents for the metal content, unless it possesses a rare mint error not visible in the image. Unaltered, uncirculated 1964 Lincoln Cents typically range from $0.15 to a few dollars depending on grade. Proof examples can be worth more.

For altered coins, especially those used as jewelry, specific numismatic care is less relevant as the coin's original state is compromised. However, to preserve its appearance, avoid exposing it to harsh chemicals or abrasive materials. If it's still being worn as jewelry, occasional gentle cleaning with a soft cloth and mild soap can remove surface grime, but avoid aggressive polishing which can further damage the surface.
