1955
The 1955 Double Die Penny was created due to a misalignment in the minting process at the U.S. Mint in Philadelphia. This mistake caused a dramatic doubling effect on the obverse of the coin, most noticeably in the inscriptions “LIBERTY,” “IN GOD WE TRUST,” and the date “1955.”
Because this error was initially unnoticed, many of these coins entered circulation, with some even being distributed through vending machines. Over time, collectors recognized their rarity, turning them into one of the most famous error coins in history.
Identify
The most obvious sign of a genuine 1955 Double Die Penny is the distinct doubling of letters and numbers on the obverse. This doubling is especially clear on “LIBERTY,” “IN GOD WE TRUST,” and the date “1955.” If your penny does not have these characteristics, it is likely not the rare variety.
Reverse
The reverse side of the coin should appear normal. If you notice doubling on the reverse, you might be looking at a different type of minting error rather than the famous 1955 Double Die.
Condition
Coins in Mint State (MS) condition—meaning they have little to no wear—are the most valuable. However, even circulated examples can fetch thousands of dollars, depending on their condition.
Weight
A genuine 1955 Lincoln cent weighs approximately 3.11 grams and is composed of 95% copper and 5% tin and zinc. Counterfeit coins may have different weights or compositions, so verifying this can be a crucial step in authentication.
Luster
Uncirculated examples of this penny have a distinct mint luster, which is a sheen created during the minting process. Coins with dull or worn surfaces are less valuable but can still be worth significant amounts.
Value
The value of a 1955 Double Die Penny depends largely on its condition. Here’s what recent market trends suggest:
| Condition | Estimated Value Range |
|---|---|
| Poor (G-4) | $1,000 – $1,500 |
| Fine (F-12) | $3,000 – $5,000 |
| Extra Fine (EF-40) | $10,000 – $15,000 |
| Uncirculated (MS-63) | $50,000 – $100,000 |
| MS-65 (Gem) | Up to $1 million |

Myths
Due to the high value of this coin, numerous myths and scams exist. Here’s what to watch out for:
Poor
Some sellers claim that “Poor Man’s Doubled Die” pennies are the same as the rare variety. These pennies have minor doubling but lack the strong doubling effect of the genuine 1955 Double Die Penny. While they may be collectible, they are not worth nearly as much.
Altered
Scammers sometimes alter regular 1955 pennies to make them look like Double Die varieties. Always verify your coin through professional grading services before making any assumptions about its value.
Sellers
Be cautious when buying or selling online. Stick to reputable dealers and insist on third-party authentication before making a purchase. Many fake listings exist on online marketplaces.
