Valuable varieties & errors
1893/2 Overdate
rareThe Mint punched an 1893 date over a die originally dated 1892 rather than waste the die. Traces of the underlying 2 remain visible beneath the 3 in the date.
1905-O Micro O
rareSome 1905 New Orleans dimes were struck with a tiny O mint mark punch intended for a smaller-format die. The undersized mark is obvious once you compare it against a normal 1905-O.
Error types found on this series

Doubled Die (Obverse)
The front design shows a second, shifted image because the die itself was made doubled.

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

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.

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