The 1950-D Jefferson Nickel is known for its error in the mintmark placement, where the “D” mintmark is faint and weakly struck. This error occurs due to a worn or improperly aligned die, which resulted in the “D” mintmark being less visible than it should have been.

While the coin may seem minor to the untrained eye, collectors recognize it as an important error in the Jefferson Nickel series. A 1950-D Jefferson Nickel with a weak mintmark can be worth anywhere from $100 to $1,500, with higher-quality examples bringing in the most value.

The 1982 No Mintmark Roosevelt Dime is a rare error that occurred when some dimes were struck without the mintmark that should have been present. This error is particularly notable because, in 1982, the mintmark was supposed to be located on the reverse of the coin, above the date.

Some of these dimes slipped through the minting process without this vital detail. Because of its rarity, the 1982 No Mintmark Roosevelt Dime is a valuable error coin. It typically sells for $200 to $500, with higher-quality coins in mint condition fetching even more.

The 1999 Wide AM Lincoln Cent is a sought-after error coin caused by a misalignment of the “A” and “M” in “AMERICA” on the reverse of the coin. This error happened due to the incorrect dies being used during the minting process. Most 1999 Lincoln Cents have the normal close AM design, but the wide AM is a distinct feature of the error coin.

This coin is one of the most popular errors in modern U.S. coinage. A 1999 Wide AM Lincoln Cent in decent condition can be worth anywhere from $50 to $300. Coins in excellent condition or with additional characteristics may command even higher prices.

The 1944 Steel Lincoln Cent is rare because it was meant to be struck on copper planchets, but a few steel planchets were left in the Mint’s machines.
