These mint errors are rare occurrences that have the potential to turn everyday pocket change into priceless treasures.
In this article, we’ll explore 12 shocking mint errors that have turned ordinary coins into valuable collectibles worth thousands or even millions of dollars.
12 Shocking Mint Errors
1. 1955 Doubled Die Lincoln Cent
The 1955 Doubled Die Lincoln Cent is one of the most famous and valuable mint error coins in U.S. history. Due to a misalignment during the minting process, the obverse (front) side of the coin was struck twice, creating a noticeable doubling effect on the inscriptions and the date.
Key Details:
- Date: 1955
- Error Type: Doubled die on the obverse side
- Value: $1,000 to $25,000 (depending on condition)
2. 1969-S Doubled Die Lincoln Cent
Another iconic mint error is the 1969-S Doubled Die Lincoln Cent. Similar to the 1955 version, this coin shows significant doubling on the obverse, most notably in the inscriptions “LIBERTY” and “IN GOD WE TRUST.”
Key Details:
- Date: 1969
- Mint: San Francisco
- Error Type: Doubled die obverse
- Value: $30,000 to $100,000 (depending on condition)
3. 2004 Wisconsin State Quarter (Extra Leaf Error)
The 2004 Wisconsin State Quarter gained fame when collectors discovered two varieties of errors: an “extra leaf high” and an “extra leaf low” near the corn stalk on the reverse side of the coin. These additional leaves were caused by die gouges, and they dramatically increased the coin’s value.
Key Details:
- Date: 2004
- Error Type: Extra leaf varieties on the reverse side
- Value: $300 to $3,000 (depending on condition)
4. 1943 Bronze Lincoln Cent
The 1943 Bronze Lincoln Cent is one of the most valuable U.S. coins due to a major mint error. During World War II, the U.S. Mint switched to using steel for pennies to conserve copper for the war effort. However, a few bronze planchets from 1942 were mistakenly used in 1943, creating these rare and valuable error coins.
Key Details:
- Date: 1943
- Error Type: Struck on bronze planchet instead of steel
- Value: $100,000 to $1.7 million
5. 1974 Aluminum Lincoln Cent
The 1974 Aluminum Lincoln Cent was part of an experimental series created by the U.S. Mint to reduce costs by using aluminum instead of copper for pennies. However, these coins were never released into circulation. A few examples survived, and they are considered extremely valuable.
Key Details:
- Date: 1974
- Error Type: Struck on aluminum planchet
- Value: Estimated $250,000 to $2 million
6. 2000 Sacagawea Dollar (Wounded Eagle Error)
The 2000 Sacagawea Dollar contains a fascinating error known as the “Wounded Eagle.” On this coin, a die gouge creates the appearance of a spear or cut running through the eagle on the reverse side, giving the eagle a wounded look.
Key Details:
- Date: 2000
- Error Type: Die gouge on reverse side (Wounded Eagle)
- Value: $100 to $5,000
7. 1983 Copper Lincoln Cent
The 1983 Copper Lincoln Cent is an anomaly because, after 1982, the U.S. Mint began producing pennies made from copper-plated zinc instead of solid copper. However, a few copper planchets were still used in 1983, making this coin a rare and valuable error.
Key Details:
- Date: 1983
- Error Type: Struck on copper planchet
- Value: $10,000 to $20,000
8. 2007 Presidential Dollar (Missing Edge Lettering)

- Value: $100 to $1,000

11. 2005 Kansas State Quarter (In God We Rust Error)
The 2005 Kansas State Quarter became famous for an unusual error where the “T” in “In God We Trust” was missing or faded, leading to the phrase appearing as “In God We Rust.” This error was caused by grease-filled dies and has become a collector’s favorite.
Key Details:
- Date: 2005
- Error Type: Grease-filled die leading to missing “T” in “Trust”
- Value: $50 to $500
12. 1982 No Mint Mark Roosevelt Dime
