1955 doubled-die cent
The 1955 doubled die cent is a die variety that occurred during production of the one cent coin at the United States Mint in 1955.[1] This variety is often mistakenly referred to as an error. Error coins occur on a per strike basis, while die variety coins are produced for every strike with a specific die pair as is the case with the 1955 doubled die cent.

When a modern coin die is created, it is struck from a working hub, which places the incuse image onto the die that will subsequently be used to strike coins. Normally, this requires multiple blows. In 1955, one of the working obverse dies at the Philadelphia Mint was misaligned on the second blow from the working hub, thus resulting in a doubled image. Due to the manner in which this hubbing was carried out, it most noticeably affected the date and inscriptions, with very little doubling visible on the bust of Lincoln. These doubled features were visible on all of the coins struck from this die. It is estimated that 24,000 of these coins were struck, all during one night shift at the Philadelphia Mint. They were originally found in New England, and many were distributed in cigarette packs in vending machines. The price of the cigarettes was 23 cents per pack, and two pennies were included to even up the price to the quarter required to buy from the machine.
The 1955 doubled die is one of the most famous die varieties in US coinage. Very few exist today in totally mint condition, as all were discovered while in circulation. Over the years, many counterfeits of this coin have surfaced. It is advised to seek expert opinion before purchasing this coin if not certified by one of the top numismatic certification companies.
A seemingly similar variety to the 1955 doubled die is die deterioration doubling, or "poor man's double die." It is caused when the design on a worn die becomes eroded and distorted. It is much more common than the actual doubled die, and as such it sells for only a few dollars.
