The 1955 Doubled Die Obverse Lincoln Cent is the most famous doubled die in American numismatics. The doubling is dramatic — visible to the naked eye on the date and the words IN GOD WE TRUST and LIBERTY — and the coin has been a recognized collector key date almost since it left the press. Today, even a worn example trades in four figures.
This guide covers what the coin is actually worth at every grade, how the doubled die was created, and how to tell a real DDO from the much more common machine doubling that gets mistaken for it.
What it's worth (catalog values by grade)
Values are pulled from the LuckyCoin catalog. The full grade-by-grade chart, including every Sheldon-scale grade and live eBay listings, lives on the 1955 DDO coin page.
| Grade | Approximate Value | Notes |
|---|---|---|
| G-4 | $1,100 | Heavy wear; doubling still clearly visible |
| F-12 | $1,200 | Most details visible; sharp doubling on date |
| VF-20 | $1,400 | Most details sharp |
| XF-40 | $1,800 | Trace wear only |
| AU-58 | $2,500 | Faintest wear, mint luster intact |
| MS-63 | $6,000 | No wear; minor contact marks |
For comparison, the regular 1955 Philadelphia (no doubling) is a common date worth $0.05 in worn condition and only $3 in MS-65. The entire price premium of the DDO comes from the variety status.
What is a doubled die, exactly?
Coin dies are made by impressing a working hub multiple times to transfer the design. If the working die rotates or shifts between impressions, the result is a die that strikes coins with two slightly offset versions of the design — one set of letters, dates, or details sitting next to itself.
On the 1955 DDO, the die-hub misalignment was significant enough that the doubling is visible without magnification. Every coin struck by that single defective die shows the same characteristic doubling, in the same direction, in the same locations.
How to tell a real 1955 DDO from machine doubling
Most coins that get submitted as "1955 DDOs" are actually showing machine doubling (also called strike doubling) — a totally different and worthless effect caused by die bounce or chatter at the moment of strike. Machine doubling looks flat and shelf-like, sits at the edges of letters, and varies coin to coin depending on press conditions.
Real doubled-die doubling is different in three specific ways:
- Rounded, not flat. The doubled letter or digit has full three-dimensional relief, not a flat shelf. Each instance of the doubled element looks like a complete struck-up character.
- Same on every coin.Every 1955 DDO struck shows the doubling in the exact same direction and the same intensity. If two coins both claim to be 1955 DDOs but the doubling looks different, at least one of them isn't.
- Visible on specific elements. On the 1955 DDO, the doubling is clearest on the date (1955), LIBERTY, and IN GOD WE TRUST. Doubling that appears only on a portion of the inscription, or on the reverse, is not the 1955 DDO.
For any coin you suspect is a real 1955 DDO above $300, professional authentication by PCGS or NGC is the only safe path. Both have encapsulated thousands of authentic examples and reject machine doubling immediately.
How many were made?
The Mint did not track how many 1955 DDO coins were struck — the doubled die was caught and pulled from production after a partial-day run, but exactly how many cents went out the door before the catch is unknown. Of the roughly 40,000 coins struck from the defective die, an estimated 24,000 escaped the Mint into circulation (the remainder were caught in the operator's bin and destroyed), most of them distributed in mixed bags to banks in the northeastern US — particularly central and western Massachusetts and upstate New York — during the summer of 1955.
That partial-day production explains the steep price ramp from circulated grades (where most surviving examples sit) to mint state (very few were saved at the time of issue).
Other famous Lincoln cent doubled dies
The 1955 is the most famous, but two other Lincoln cent doubled dies regularly trade in collector markets:
- 1969-S Doubled Die Obverse — Memorial-era, dramatic doubling on date and inscriptions, a rarer find that reaches $11,000 in XF-40 and $50,000 in MS-63 per the catalog.
- 1972 Doubled Die Obverse — more accessible, $170 in G-4 to $600 in MS-65. A common entry point for collectors building a doubled-die set.

- How can I tell if my 1955 penny is the doubled die?
- Look at the date 1955, LIBERTY, and IN GOD WE TRUST on the obverse. On a real DDO, each digit and letter shows clear, rounded doubling — like two slightly offset complete characters. If the doubling looks flat or shelf-like, that's machine doubling, which is worthless. For any candidate worth submitting, send it to PCGS or NGC.
- What is a 1955 doubled die penny worth?
- In Good (G-4) condition, around $1,100. In Fine (F-12), about $1,200. In Mint State (MS-63), around $6,000. Top-grade examples in MS-65 RD reach much higher.
- How rare is the 1955 doubled die?
- The Mint pulled the defective die after a partial-day run, so roughly 40,000 coins were struck from the defective die and about 24,000 reached circulation — extremely scarce in mint state because almost none were saved at the time of issue.
- Are 1955 doubled die pennies still in circulation?
- Essentially no. The variety has been recognized as a key date for 70+ years, and most surviving examples have been pulled from circulation into permanent collections. Modern finds almost always come from inherited collections, estate-sale coin lots, or mislabeled dealer inventory.
- How do I authenticate a 1955 doubled die before buying?
- For any coin priced over a few hundred dollars, insist on a PCGS, NGC, or ANACS slab. All three grading services have authenticated thousands of 1955 DDOs and reject machine doubling, altered dates, and other counterfeits. A raw coin at full retail price is a red flag.
