1. 1955 Doubled Die Lincoln Cent
One of the most iconic error coins, the 1955 Doubled Die Lincoln Cent, is easily recognized for its striking double inscriptions and numerals.
How the Error Happened
The doubling occurred during the die manufacturing process when the hub struck the die twice but slightly misaligned the second time. This error resulted in a noticeable doubling effect on the date and the word “LIBERTY.”
Value to Collectors
This coin is highly valued for its rarity and visual appeal. Depending on its condition, it can range from $1,000 to over $20,000 in auctions and private sales.
2. 1943 Copper Penny
The 1943 Copper Penny is a wartime anomaly that stands as one of the rarest and most sought-after error coins.
What Went Wrong?
During World War II, copper was reserved for military uses, so pennies were supposed to be made from zinc-coated steel. However, a few copper planchets from 1942 were mistakenly used, creating a handful of 1943 copper pennies.
Why It’s Valuable
The rarity of this error makes it extremely desirable. Depending on its condition, the coin has fetched prices between $100,000 and over $1,000,000, setting records at auctions.
3. 2000 Sacajawea Dollar/Washington Quarter Mule
This modern-day error coin combines the design features of two distinct coins: the Sacajawea Dollar and the Washington Quarter.
How It Happened
In 2000, an inexperienced mint operator mistakenly paired a Washington Quarter obverse die with the reverse die of the Sacajawea Dollar. These mismatched dies created the rare “mule” error.
What It’s Worth
Collectors have paid between $50,000 and $100,000 for these coins, making it one of the most valuable mint errors of modern times.
4. 1974 Aluminum Penny
The 1974 Aluminum Penny represents a fascinating experiment in cost reduction that never saw full circulation.
What Makes It Unique
To cut costs, the U.S. Mint struck approximately 15,000 aluminum pennies and distributed them to Congress for approval. However, the plan was scrapped due to concerns about wear and visibility. Most of the coins were destroyed, but a few managed to escape into private hands.
Market Value
This experimental coin is incredibly rare, with one example fetching $250,000. Legal disputes surrounding ownership have added to its mystique.
5. 1937 D Three-Legged Buffalo Nickel
The 1937 D Three-Legged Buffalo Nickel is famous for its visually striking error: the buffalo on the reverse side appears to have only three legs.
The Mistake
Over-polishing of the die at the Denver Mint removed the front leg of the buffalo, creating this unique and collectible error.
Collector Interest
This coin is valued between $550 and $5,000, depending on its condition, and remains a favorite among numismatists.
6. 1982 No Mint Mark Dime
A seemingly small omission, the lack of a mint mark on the 1982 No Mint Mark Dime makes it a notable modern error coin.
The Issue
The die used to strike this dime accidentally omitted the “P” mint mark that was standard for coins minted in Philadelphia.
Value
This relatively affordable error coin sells for $200 to $1,000, making it an accessible entry point for collectors interested in mint errors.
7. 1999 Wide “AM” Penny
The 1999 Wide “AM” Penny showcases a subtle but intriguing minting error involving the spacing of letters.
What Happened?
Proof coin dies, which have wider spacing between the letters “A” and “M” in “AMERICA,” were mistakenly used to strike circulation coins, resulting in this rare variety.
Why It’s Collectible
With prices ranging from $300 to $2,000, this coin’s rarity and subtle error make it a fascinating addition to any collection.
8. 2004 Wisconsin Extra Leaf Quarter
This error coin is known for an extra leaf that appears on the reverse side’s corn stalk design.
The Story Behind the Error
It’s believed that this error was intentional, added during the die creation process at the Wisconsin Mint. The extra leaf distinguishes this coin from standard quarters.
Value and Appeal
Collectors value this coin between $100 and $1,500, depending on its condition, as the added detail makes it a unique find.
