Known Errors

Wide AM Reverse

The proof reverse die was used to strike a small number of regular business-strike pennies. The letters A and M in AMERICA are clearly separated instead of touching at the base.

How to check: Examine the bottom of A and M in AMERICA. If there is a clear gap between the letters, you have a Wide AM. The FG initials are also positioned farther from the Memorial.

$300 - $1,500+

Doubled Die Obverse

Hub doubling visible on LIBERTY, the date, or IN GOD WE TRUST.

How to check: Use a 10x loupe to examine LIBERTY for split serifs or shadow doubling on the date.

$25 - $250

Off-Center Strike

Planchet not properly aligned at strike, producing a partial design with a blank crescent.

How to check: Look for an obviously uncentered design. The full date must remain visible for maximum value.

$10 - $150+

Die Cracks

Minor die cracks visible as raised lines through the design or along the rim.

How to check: Look for thin raised lines that don't follow the design — these are die cracks, not damage.

$5 - $50

Weak Strike

Insufficient pressure produces a coin with soft, mushy details.

How to check: Compare to a sharply struck 1999 cent — a weak strike will lack detail in Lincoln's hair and the Memorial steps.

$2 - $20
