Is Your 1955/55 DDO Lincoln Cent Real? Authentication Guide for This Key Date

Introduction

With counterfeits flooding the market, knowing the specific diagnostic points for this item is critical. The 1955/55 DDO Lincoln cent represents one of the most significant doubled die varieties in American numismatics, making it a prime target for sophisticated counterfeiters. This authentication guide will walk you through the essential testing methods and diagnostic markers to verify authenticity.

Historical Significance

The 1955/55 DDO (Doubled Die Obverse) Lincoln cent is considered one of the most dramatic and valuable doubled die varieties in U.S. coinage history. The doubling is visible to the naked eye, particularly in the date and lettering. This variety was created when the hub and die were misaligned during the minting process, resulting in the distinctive doubled appearance that collectors prize.

Production Context

This variety was discovered shortly after release and quickly became a sensation among collectors. The dramatic doubling, especially visible in the date “55” and the word “LIBERTY,” makes it one of the most recognizable varieties in American numismatics. The coins were primarily released through circulation in the northeastern United States, with estimates suggesting approximately 20,000 to 24,000 pieces entered circulation.

Identifying Key Markers

Weight Verification

Authentic 1955 Lincoln cents should weigh 3.11 grams, consistent with copper-alloy cents minted from 1864 to 1982. Any significant deviation from this weight is an immediate red flag. Use a precision scale accurate to at least 0.01 grams for verification. Counterfeiters often use incorrect metal compositions, resulting in weight discrepancies.

Magnetic Properties

Since the 1955 cent was struck in bronze (95% copper, 5% tin and zinc), it should not be attracted to a magnet. If your coin is magnetic, it’s either a copper-plated zinc cent from 1982 or later, or a counterfeit made from magnetic materials. This simple test can quickly eliminate many fakes.

Doubling Characteristics

The doubling on authentic specimens shows specific characteristics:

• The date “55” shows clear, horizontal doubling
• The word “LIBERTY” exhibits strong doubling, particularly in the “BER” portion
• The motto “IN GOD WE TRUST” shows doubling, most noticeable in “WE” and “TRUST”
• The doubling should be consistent in direction and magnitude across all affected areas

Die Markers and Diagnostics

Authentic 1955/55 DDO cents exhibit specific die markers that counterfeiters often miss:

• A die crack often appears through the “T” in “CENT” on the reverse
• Die polishing lines may be visible in the fields
• The mint mark (if present) should be properly positioned and not doubled
• The overall strike quality should be consistent with 1950s minting technology

Common Fakes and Alterations

Several types of counterfeits exist in the marketplace:

Altered Dates

Some counterfeiters alter common 1955 cents by adding artificial doubling. These can often be detected by:

• Examining the metal flow at the junction of altered areas
• Checking for tool marks or file marks around the date
• Using magnification to identify inconsistencies in the doubling pattern

Cast Counterfeits

Cast counterfeits often show:

• Pitting or granular surfaces
• Loss of fine detail, especially in the hair and Lincoln’s profile
• Incorrect weight due to the casting process
• Soft, rounded edges rather than sharp, squared edges

Transfer Die Fakes

More sophisticated counterfeits use transfer dies and may be harder to detect. Look for:

• Subtle differences in the doubling pattern compared to known genuine examples
• Inconsistent luster or surface texture
• Die deterioration that doesn’t match the expected pattern for authentic coins

Testing Methods

Visual Examination

Begin with careful visual inspection under proper lighting:

1. Use a quality magnifying glass (5x to 10x) to examine the doubling
2. Check for proper mint luster and surface texture
3. Look for signs of tooling, casting, or other manufacturing irregularities
4. Compare your coin to high-resolution images of authenticated specimens

Precision Weighing

Weigh your coin using a calibrated digital scale:

• Ensure the scale is properly calibrated
• Handle the coin with cotton gloves to avoid adding skin oils
• Verify the weight is 3.11 grams ± 0.02 grams
• Document the weight for your records

Magnetic Testing

Perform a simple magnetic test:

• Use a strong rare-earth magnet
• Hold the magnet near (but not touching) the coin
• Observe whether there is any attraction
• Remember: genuine 1955 cents should show no magnetic attraction

Professional Authentication

For high-value specimens, professional authentication is recommended:

• Submit to PCGS, NGC, ANACS, or ICG for certification
• Professional graders use multiple diagnostic tools and reference databases
• Certified coins come with guarantees of authenticity
• Third-party grading also protects your investment and aids in future sales
