Why Coin Errors Matter
Coin errors and misprints have fascinated collectors for decades. Whether it’s a doubled die, an off-center strike, or a rare overdate, mint errors offer a glimpse into the manufacturing quirks of U.S. coinage — and sometimes, into extraordinary value.
Collectors love error coins for:
- Their rarity and visual uniqueness
- The chance to find valuable pieces in everyday change
- Their connection to U.S. Mint history and craftsmanship
- Opportunities for massive returns compared to face value
Some errors are minor curiosities worth a few dollars. Others, like the 1955 Doubled Die Lincoln Cent or the 1937-D 3-Legged Buffalo Nickel, have achieved legendary status, commanding four-, five-, and even six-figure prices.
Whether you’re checking an old collection or hunting through pocket change, learning to spot errors opens up an exciting and rewarding corner of numismatics.
Types of U.S. Coin Errors
Understanding the different types of errors is crucial for collectors. Here are the major categories:
- Doubled Dies: Caused by a misalignment during die creation, resulting in a noticeable doubling of design elements like dates and lettering.
- Off-Center Strikes: Coins struck when the blank (planchet) is improperly positioned, resulting in missing parts of the design.
- Broadstrikes: Coins struck without a collar, causing them to spread and appear larger than normal.
- Clipped Planchets: Coins missing a curved piece, often from a misfeed in the blanking machine.
- Wrong Planchet Strikes: Coins accidentally struck on blanks meant for a different denomination.
- Die Cracks & Cud Breaks: Raised lines or missing sections caused by cracked or damaged dies.
Each type carries its own appeal and collectible premium based on visibility, severity, and scarcity.
