State quarters, minted from 1999 to 2008, have fascinated collectors since their release, with a few rare examples becoming especially valuable over time. While many state quarters hold sentimental value, a handful stand out due to unique errors, limited production, and historical appeal. Some of these coins, prized by numismatists, have skyrocketed in value, with a few estimated to be worth as much as $150 million.
Could one of these coins be hiding in your collection? Here are some of the rarest state quarters to look out for and what makes them so valuable.
The 1999 Delaware State Quarter: The “Spitting Horse” Error
As the first coin released in the state quarters series, the 1999 Delaware quarter is notable for its design honoring the historic 1776 ride of Caesar Rodney. However, what makes this coin especially valuable is the “Spitting Horse” mint error. This error appears as a line extending from the mouth of the horse on the coin, giving the impression of the horse “spitting.” Known for its rarity and appeal to collectors, pristine examples of this quarter with the error can command incredibly high prices.
The 2004 Wisconsin State Quarter: The “Extra Leaf” Error
The 2004 Wisconsin State Quarter, which depicts a cow, a wheel of cheese, and an ear of corn, features a unique minting error known as the “Extra Leaf.” Due to this mistake, an additional leaf appears on the corn stalk, with two variants: a high extra leaf and a low extra leaf. This error has made the Wisconsin quarter highly desirable, and collectors continue to seek out these coins for their collections, with the coin’s value soaring over time.
The 2005 Kansas State Quarter: The “In God We Rust” Error
The 2005 Kansas State Quarter, featuring a bison, has become famous for a humorous yet valuable mint error. Some of these coins display the phrase “In God We Rust” instead of “In God We Trust” due to a grease-filled die, which caused the “T” to be faint or missing. This unusual error has made the Kansas quarter a favorite among collectors, with its value climbing as a result of its rarity and the widespread appeal of its unusual error.
Other Valuable State Quarters with Noteworthy Errors
While the Delaware, Wisconsin, and Kansas quarters are among the most famous error coins, several other state quarters also contain unique and valuable errors. Here’s a look at some other quarters collectors prize:

The fact that many of these errors were caught early and corrected further enhances the value of the limited number of error coins that were released.
