What Is the 1955 Doubled Die Penny 2?
The 1955 doubled die penny is a well-known error coin produced at the U.S. Mint. The doubling affects the obverse (front) design, causing letters and elements to appear doubled.
“Penny 2” often refers to a specific strong variety or a second notable doubled example from that year. Collectors focus on the clarity of doubling and the coin’s condition when assigning value.
How to Identify the 1955 Doubled Die Penny 2
Identification begins with close visual inspection. Use good lighting and a 5x to 10x loupe or a macro camera for clear views.
Look for these key markers:
- Pronounced doubling on the word “LIBERTY” and the date “1955” on the obverse.
- Shadow-like replicas of letters, often offset slightly right and above the original strike.
- Doubling on the motto “IN GOD WE TRUST” and parts of Lincoln’s profile sometimes visible.
What Not to Confuse With Doubling
Machine doubling (die shift) and post-strike damage can mimic doubled dies. True doubled dies are on the die itself, so the doubling is sharp and consistent across multiple coins struck by that die.
Use magnification to confirm that the doubled features are well-defined, not fuzzy or misaligned in a way typical of mechanical contact marks.
Authentication and Grading for 1955 Doubled Die Penny 2
If you suspect you have a 1955 doubled die penny 2, consider professional authentication. Reputable services include PCGS and NGC, which will certify the variety and assign a grade.
Grading matters because a sharp doubled die in high grade is significantly more valuable than the same variety heavily worn. Look for:
- Strike quality and surface preservation
- Luster and contact marks
- Presence of original mint toning
Value Factors for the 1955 Doubled Die Penny 2
Value depends on variety, grade, and market demand. Strongly doubled examples in mint state can command premiums from collectors and specialty dealers.
Typical value drivers include:
- Clarity of doubling: the crisper the doubling, the higher the value.
- Grade: MS (Mint State) examples are most desirable.
- Eye appeal and originality of surfaces.
Practical Steps to Examine a Coin
Follow a consistent process to evaluate a suspected 1955 doubled die penny 2. Keep notes and photos for reference.
- Wash hands and use cotton gloves to avoid oils on the coin.
- Place the coin on a neutral, nonreflective surface.
- Examine under 5x–10x magnification and photograph both obverse and reverse with macro focus.
- Compare to reference images from trusted numismatic sources or variety guides.
Tools That Help
- 5x–10x jeweler’s loupe
- Macro-capable camera or phone with macro lens
- Reference books or online variety databases
The 1955 doubled die is one of the most famous U.S. penny errors and is often used as a teaching example for identifying doubled dies due to its strong, easy-to-recognize doubling.
Buying and Selling Tips for 1955 Doubled Die Penny 2
If you plan to buy, buy from reputable dealers or auction houses that provide clear high-resolution images and return policies. Ask for certification when possible.
When selling, present clear photos, document provenance, and consider professional grading to maximize buyer confidence and price.
Checklist Before Purchase
- High-resolution photos of obverse and reverse
- Magnified view of the suspected doubled areas
- Seller history and any grading/certification documents
- Return policy and buyer protections
Care and Storage
Keep the coin in a stable, dry environment away from extreme temperatures. Use inert holders like Mylar flips or acid-free card mounts for short-term storage.
Avoid cleaning the coin; cleaning can drastically reduce value, especially for error coins where original surfaces matter.
Case Study: A Local Discovery
A collector at a regional coin show bought a roll of mixed 1955 pennies for a small price. Among them was a strong doubled obverse showing clear doubling on LIBERTY and the date.
After photographing the coin and comparing it to online references, the collector sent the coin to a grading service. The slabbed coin sold later at auction to a specialized collector for several thousand dollars, demonstrating how careful identification and certification can unlock value.
Final Practical Advice
Learn the specific traits of the 1955 doubled die penny 2 by comparing multiple authenticated examples. Patience and careful documentation are essential.
When in doubt, seek professional grading and use trusted marketplaces. Proper identification, authentication, and presentation consistently lead to better outcomes for collectors and sellers alike.
