What is the 1955 Doubled Die Penny 2?
The 1955 doubled die penny is a well-known Lincoln cent error where doubling appears on the obverse design. The doubling affects letters and numbers, producing a distinct, often dramatic, secondary image offset from the primary design.
The term “1955 Doubled Die Penny 2” refers to a specific way collectors describe varieties and study differences in doubling. Whether you call it Type 1, Type 2, or simply the 1955 doubled die, the key is visible, consistent doubling produced during hubbing at the mint.
How to identify a 1955 Doubled Die Penny 2
Identification relies on clear visual markers and consistent patterns of doubling on the obverse. Use magnification and good lighting to inspect suspects closely.
Obverse details on 1955 Doubled Die Penny 2
Focus on the obverse of the coin. Look for doubling on “IN GOD WE TRUST,” “LIBERTY,” and the date. The doubling is often heavy, making letters look thickened or showing a distinct shadowed outline.
Tools and methods
Use a 10x loupe or a low-power stereo microscope for initial inspection. Strong, angled light helps reveal small horizontal or diagonal shifts that indicate doubling.
Compare the suspect coin to a confirmed normal 1955 Lincoln cent to see differences in letter spacing and stroke shapes.
Common visual markers
- Doubling on the date—especially the 5s and the first digit—appearing offset and clear.
- Thickened letters in LIBERTY and IN GOD WE TRUST with visible secondary outlines.
- Doubling that follows the contours of design elements rather than random scratch or damage patterns.
Authentication and grading for 1955 Doubled Die Penny 2
Authentication by a reputable third-party grading service is the best way to confirm a true doubled die. Services like PCGS and NGC have specialists who can identify known varieties and note the doubling on labels.
Grading affects value dramatically. Higher grade, well-centered examples with minimal wear are far more valuable than worn pieces. If you plan to sell, certification adds buyer confidence.
Watch out for counterfeits and alterations
Many fake or altered coins mimic doubling by mechanical tooling, stamping, or doubling via image editing. These can sometimes mimic doubled dies but usually lack consistent hubbing characteristics.
Red flags include irregular surface marks, inconsistent doubling across all letter forms, or evidence of added metal or tooling lines near letters.
Value ranges and what affects price
Value depends on grade, eye appeal, and certification. Circulated examples can still be valuable, while mint-state pieces command the highest prices.
- Heavily worn certified pieces: entry-level collector value.
- Mid-grade certified coins with good detail: collector and moderate investor interest.
- High-end mint-state certified coins: premium prices and auction interest.
Provenance (documented history) and attractive toning or strike quality also influence the final sale price.
Care, handling, and storage
Handle coins by the edges to avoid fingerprints and oils. Avoid cleaning, as cleaning reduces value and can be detected by graders.
Store certified coins in inert holders or capsules, and uncertified examples in acid-free flips or coin envelopes. Keep coins in a stable, low-humidity environment away from direct sunlight.
Small real-world case study
A local collector discovered a heavily doubled 1955 Lincoln cent while sorting circulated coins from a bank roll. The doubling was obvious on the date and LIBERTY, prompting the collector to seek authentication.
After submission to a major grading service, the coin was certified as a genuine 1955 doubled die. The certified coin sold through a specialist dealer to a collector who wanted a mid-grade certified example. The steps—identify visually, submit to an expert, and sell through trusted channels—kept the sale straightforward and credible.
Practical tips for buyers and sellers of 1955 Doubled Die Penny 2
