Error types found on this series

Doubled Die (Reverse)
Same as a doubled die obverse, but the doubling appears on the back of the coin.

Grease-Filled Die (Struck Through Grease)
Grease and debris packed into the die's recesses blocked part of the design, leaving weak or missing details.
Missing Clad Layer
A dime, quarter, or half is missing its outer silver-colored layer on one side, exposing the copper core.

Off-Center Strike
The blank wasn't centered when struck, so part of the design is missing and part of the coin is blank.

Clipped Planchet
A bite-shaped piece of the coin is missing because the blank was punched from an already-punched part of the metal strip.

Die Crack
A crack in the die fills with metal during the strike, leaving a thin raised line on the coin.

Strike-Through
A foreign object — cloth, wire, grease, or a metal fragment — was on the blank when it was struck, leaving its impression in the coin.
