The U.S. State Quarters Program (1999–2008) was a monumental success, featuring designs that celebrated each state’s unique history and culture. While most state quarters are worth face value, a select few with minting errors have become highly sought after by collectors, some worth millions of dollars. These accidental imperfections turn ordinary coins into extraordinary treasures, offering a glimpse into the quirks of the minting process.
Let’s dive into the notable state quarters with minting mistakes and their surprising values.
Delaware’s “Spitting Horse” Quarter (1999)
The Delaware quarter, featuring Caesar Rodney on horseback, was the first in the state quarters series. However, a minting error known as the “Spitting Horse” has made some of these coins legendary.
Key Features:
- Error: A die crack near the horse’s mouth creates the illusion of saliva.
- Value: Estimated up to $150 million for high-grade examples.
- Collector Appeal: This error is iconic and instantly recognizable, making it highly desirable.
This quarter is an exceptional example of how a seemingly small flaw can transform a coin into a prized collector’s item.
Wisconsin’s “Extra Leaf” Quarters (2004)
Symbolizing Wisconsin’s agricultural heritage, this quarter features a cow, cheese, and a corn plant. A unique minting error added an extra leaf to the corn stalk, creating two distinct error variants:
Key Features:
- Error Variants:
- High Extra Leaf: The added leaf appears higher on the stalk.
- Low Extra Leaf: The added leaf appears lower.
- Value: Significant premiums over face value, depending on condition.
- Collector Appeal: These variations are rare and highly sought after.
The extra leaf errors are a favorite among collectors due to their rarity and unique design flaw.
Kansas’s “In God We Rust” Quarter (2005)
The Kansas quarter, depicting a bison and the state motto, became infamous for its humorous “In God We Rust” error.
Key Features:
- Error: A grease-filled die caused the letter “T” in “TRUST” to disappear.

This coin is a perfect example of how an amusing mistake can increase a coin’s value and collector interest.
