Valuable varieties & errors
1892-O Micro O
rareIn the first year of the series, a few New Orleans dies were punched with a mint mark far smaller than normal, likely from the wrong punch. It is a recognized PCGS/NGC variety and a classic Barber rarity.
Error types found on this series

Repunched Mint Mark (RPM)
The mint mark was punched into the die more than once, slightly off position, leaving a doubled letter.

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

Lamination Error
A thin layer of the coin's metal peels, flakes, or cracks off because the alloy was poorly mixed.

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.
