The Hidden Treasure: 3 Rare State Quarters Nearing $150 Million in Value

The U.S. Mint’s State Quarter Program, running from 1999 to 2008, introduced excitement into coin collecting by showcasing designs celebrating each state’s heritage. Most state quarters are only worth their face value, but some error coins have become very valuable collectibles, with certain rare examples fetching prices as high as $150 million. Let’s take a look at some of these incredible errors and what makes them so special.

Delaware “Spitting Horse” Quarter (1999)

Caeser Rodney astride his horse adorns the 1999 Delaware Quarter-the first in the State Quarters series. Because of a die crack, there resulted what collectors know as the “Spitting Horse” variety-the line extending out of the horse’s mouth looks like it is spittle.

Feature	Details
Error	Die crack near the horse’s mouth
Value	Estimated up to $150 million (high grade)
Collector Appeal	Unique and recognizable error

This silly error has helped make it the most popular State Quarter error.

Wisconsin “Extra Leaf” Quarter appeared in 2004.

The 2004 Wisconsin Quarter, celebrating the state’s agricultural heritage, features a cow, a cheese wheel, and a corn stalk. A mint error added an extra leaf to the corn stalk, with two variations:

Feature	Details
Error Variants	High extra leaf and low extra leaf
Value	Significant premiums over face value
Collector Appeal	Highly desirable due to unique design error

Both variants of the extra leaf error are prized by collectors, with values climbing significantly based on condition and rarity.
