How do I Identify a Counterfeit 1955 Double Die Cent?

The 1955 double die Lincoln one cent piece is one of the most famous examples of a mintage error that increases the value of a coin. The distinctive, double-struck image on the coin is a result of an error occurring during the creation of one of the dies used to strike 1955 Lincoln cents. Because of the relative value of this coin, counterfeiters often try to replicate it. However, it is possible to recognize a counterfeit 1955 double die Lincoln cent.

Things You'll Need

Metric scale
Metric ruler
Magnifying glass

Instructions

- 1
  Weigh and measure the coin. Counterfeiters often have difficulty creating coins that are exactly the right size. A U.S. penny should weigh 3.11 grams and have a diameter of 19 mm. If the 1955 double die cent in question does not match (or does not come extremely close to matching) these specifications, it is fake.
- 2
  Compare the physical quality of the rim of the coin to the overall condition of the coin. Compare the rim to coins of the same era in similar grades. If the rim is in significantly better shape than the faces of the coin, it might be counterfeit.
- 3
  Compare the coin with a real 1955 double die cent if at all possible. Examine the doubled areas of the coins with a magnifying glass. If your double die cent has thicker or thinner letters or numbers than the real coin, or if the letters are aligned slightly differently, you likely have a counterfeit.
- 4
  Examine the area to the left of the letter "t" in the words "One Cent" on the reverse of the coin with a magnifying glass. Authentic coins usually have small vertical lines in this area that are a result of the process used to polish U.S. dies.
- 5
  Send your coin to a coin authentication service if you think it is real. Getting your coin authenticated by an expert is the only way to be absolutely sure of its legitimacy. The Professional Coin Grading Service (PCGS), ANACS and the Numismatic Guarantee Corporation (NGC) are all widely trusted coin grading and authentication services.
