Lincoln pennies are the most widely collected U.S. coin series, and they are also among the most common coins found with mint errors. Because billions of pennies have been produced since 1909, a wide variety of error types have occurred — from subtle doubled dies to dramatic off-center strikes. Knowing which penny errors to look for can turn casual pocket change searching into a productive hobby.
Error pennies fall into several broad categories, each with different levels of scarcity and collector interest:
Doubled die varieties are among the most sought-after penny errors. Look for doubling on the date, "LIBERTY," "IN GOD WE TRUST," and the Lincoln portrait. True doubled dies show raised, separated doubling — not flat, shelf-like machine doubling.
Off-center strike pennies show a crescent of blank metal where the design is missing. The most valuable off-center pennies still show a readable date despite significant off-center striking.
Occasionally, a blank intended for a different denomination ends up in the penny press. A penny struck on a dime planchet, for example, produces a smaller, silver-colored coin with the Lincoln cent design. These are scarce and highly collectible.
Die deterioration produces raised lines (die cracks) and raised blobs at the rim (cuds) on pennies. Large cuds and dramatic die cracks are collected by variety specialists.
Foreign material impressions — grease, wire, cloth — on pennies create interesting collectible pieces, especially when the strike-through is large or the object is identifiable.
