The 50 State Quarters Program, launched by the U.S. Mint between 1999 and 2008, remains one of the most popular coin series ever produced. While most of these quarters are worth only face value—25 cents—some feature valuable errors that can make them worth a lot more. Collectors and coin enthusiasts eagerly seek out these rare mistakes, which can sometimes fetch over $1,000 at auction. Let’s explore some of the most valuable error quarters in the 50 State series and what makes them so special.
Top 50 State Quarters with Valuable Errors
- 2004 Michigan State Quarter (Struck on a Foreign Planchet) One of the most famous errors in the 50 State Quarters series is the 2004 Michigan quarter, which was accidentally struck on a foreign planchet—meaning the coin was minted on a blank intended for a different type of coin. This mistake results in a coin that’s typically worth between $1,000 and $3,000 depending on its condition and rarity.
- 2005 Wisconsin State Quarter (Extra Leaf Error) The 2005 Wisconsin quarter has two varieties of errors involving an extra leaf in the corn stalk. Some coins feature an additional leaf near the base of the corn stalk, which was not part of the original design. These coins can fetch anywhere from $500 to $1,000 or more, with the error being much more valuable when found in good condition.
- 1999 Delaware State Quarter (The “Spitting Horse” Error) The 1999 Delaware quarter, which was the first in the series, is known for its “Spitting Horse” error. This happens when excess metal is left around the horse’s mouth, giving the appearance of the horse “spitting.” Depending on its grade and the extent of the error, these quarters can be worth between $300 and $1,500.
- 2000 New Hampshire State Quarter (Double Die Obverse) The 2000 New Hampshire quarter is rare due to a double die obverse error, which causes a noticeable doubling of the lettering and date on the coin’s front. This error can make the coin worth between $500 and $1,000 or more, depending on its condition and how clear the doubling is.
- 2004 Texas State Quarter (Missing “In God We Trust” Motto) Some 2004 Texas quarters were minted without the “In God We Trust” motto, which is usually visible on the obverse of U.S. coins. This error is rare and can result in a value of $300 to $800, depending on the coin’s overall condition.
Why These Error Quarters Are Valuable
Coins with minting errors are sought after by collectors because they are considered unique, often because they were produced unintentionally. The rarity of these mistakes increases their value significantly. Errors like double strikes, off-center prints, missing or misaligned features, and wrong planchet types create coins that are different from the regular circulation pieces, making them stand out in the market.
How to Spot Valuable Error Quarters
Identifying an error quarter can sometimes be tricky, especially if you’re not familiar with the specific mistakes to look for. However, here are some tips on how to spot valuable 50 State Quarters with minting errors:
- Examine the Design: Look for any doubling of the lettering, date, or other features. These could be signs of a double die error.
- Check the Edge: Some error quarters may have off-center strikes or bent edges that deviate from the usual round shape.
- Inspect the Features: Look for unusual features like extra leaves, missing letters, or misplaced mint marks.
- Use Magnification: A magnifying glass or jeweler’s loupe can help you spot the subtle details of small errors like struck-through grease or foreign planchet mistakes.
