History of the 1955 Double Die Penny
The 1955 Double Die Penny was created at the Philadelphia Mint due to a significant misalignment during the die preparation process. When creating the working dies, a misalignment occurred that caused the image to be impressed twice in slightly different positions, creating the dramatic doubling effect that makes this coin so distinctive.
Only a relatively small batch of these error coins entered circulation before the problem was discovered and corrected. Most of the doubled die coins were caught and destroyed at the mint, but several thousand made it into circulation, primarily through cigarette vending machines in the Boston area.
The error initially went unnoticed by mint personnel and wasn’t widely recognized by collectors until the coins began appearing in circulation and eagle-eyed collectors started finding them in their pocket change. This discovery created immediate excitement in the numismatic community and established the coin’s legendary status.
Key historical points:
- Created through die misalignment during production
- Limited number entered circulation before discovery
- Primarily distributed through vending machines in Boston area
- Became famous after collectors began finding them in circulation
The coin’s fame grew rapidly as word spread through collector networks, and it quickly became the poster child for dramatic mint errors that could be found in everyday pocket change.
Key Identifying Features
The doubling on the 1955 Double Die Penny is dramatic and easily visible to the naked eye, which distinguishes it from subtle varieties that require magnification to detect. The most obvious doubling appears on “LIBERTY” and the date “1955,” where you can clearly see a second, slightly offset impression.
The doubling also appears prominently on “IN GOD WE TRUST,” where the letters show the same dramatic offset effect. This doubling is so pronounced that it’s sometimes called “machine gun doubling” because of how obvious and striking it appears.
It’s crucial to distinguish this genuine doubled die from machine doubling, which can occur during the striking process and creates a different appearance. True doubled die errors show crisp, clear doubling, while machine doubling typically appears as flat, shelf-like extensions of the letters.
Lesser varieties and minor doubled dies from 1955 also exist, but they show much more subtle doubling that’s barely visible compared to the famous major variety that collectors seek.
Value Factors
Condition plays the most significant role in determining a 1955 Double Die Penny’s value. Even heavily circulated examples in Good condition can be worth several hundred dollars, while uncirculated specimens can reach into the thousands or even tens of thousands of dollars for exceptional examples.
Eye appeal and strike quality matter tremendously, especially for higher-grade examples. Coins with full, strong doubling and attractive surfaces command premium prices over examples with weak strikes or surface problems like scratches or corrosion.
Certified authenticity has become increasingly important as the coin’s value has risen and counterfeits have appeared in the marketplace. Professional grading and authentication by services like PCGS or NGC provides buyers with confidence and typically results in higher market prices.
The coin’s provenance and documentation can also affect value, especially for high-grade examples where every detail matters to serious collectors willing to pay premium prices.
Grading the Coin
Professional grading services like PCGS and NGC have become essential for valuable 1955 Double Die Pennies, providing both authentication and condition assessment that the market trusts. These services use standardized grading scales that help establish consistent market values.
Grades typically range from Good (G-4) for heavily worn examples up to Mint State (MS-60 and higher) for uncirculated coins. Even the difference between MS-64 and MS-65 can represent thousands of dollars in value for this particular coin.
Higher grades dramatically increase value because uncirculated examples are much rarer than circulated ones. Most 1955 Double Die Pennies that survived were spent and show wear from circulation, making high-grade examples extremely desirable.
Professional grading also helps distinguish genuine examples from the sophisticated counterfeits that have appeared as the coin’s value has increased, providing peace of mind for buyers investing significant money.
Buying Tips for Collectors
Always purchase 1955 Double Die Pennies from reputable dealers, established auction houses, or certified online platforms that stand behind their authenticity guarantees. The coin’s high value has attracted counterfeiters, making source credibility crucial.
Request professional certification from PCGS or NGC for any significant purchase. While certification costs money, it’s essential insurance against counterfeits and provides standardized grading that supports market value.
Be extremely wary of deals that seem too good to be true, especially from private sellers or unestablished sources. If someone is offering a high-grade example for substantially below market value, there’s probably a reason why.
Research current market values through recent auction results, price guides, and dealer inventories to understand what you should expect to pay for different grades and eye appeal levels.
Caring for Your 1955 Double Die Penny
Proper storage in archival-quality holders or professional grading slabs protects your coin from environmental damage and handling wear. If your coin isn’t professionally graded, use inert plastic holders designed specifically for coin storage.
Never attempt to clean your 1955 Double Die Penny, regardless of its apparent condition. Cleaning almost always reduces value significantly, and even gentle cleaning can cause microscopic damage that affects grading and market acceptance.
Control humidity and temperature in your storage area to prevent corrosion and environmental damage. Store coins in a cool, dry place away from fluctuating conditions that can cause problems over time.
Essential care practices:
- Use proper holders designed for long-term coin storage
- Handle with cotton gloves to avoid fingerprints and oils
- Maintain stable environmental conditions
- Never clean or attempt to “improve” the coin’s appearance
Handle the coin minimally and always with clean cotton gloves to avoid transferring oils and acids from your skin that can cause long-term damage.
Conclusion
The 1955 Double Die Penny represents the holy grail of error coins for many U.S. collectors, combining dramatic visual appeal with genuine rarity and historical significance. Its distinctive doubling makes it instantly recognizable, while its limited survival has created strong collector demand that continues to drive values higher.
For serious collectors, this coin serves as both a treasured centerpiece and a potentially strong investment, provided you focus on authentication, accurate grading, and proper preservation. The key is understanding what you’re buying and ensuring you’re getting genuine quality.
Whether you’re hoping to find one in circulation (increasingly unlikely but still possible) or planning to purchase one for your collection, the 1955 Double Die Penny remains an iconic piece of American numismatic history that rewards collectors who do their homework and buy wisely.
