Coin: The State Quarter program, which ran from 1999 to 2008, produced some of the most interesting and valuable modern coins in U.S. history. While most state quarters remain worth their face value of 25 cents, certain rare errors have transformed ordinary quarters into highly valuable collectibles. Some of these error coins are estimated to be worth as much as $150 million, making them among the most valuable modern U.S. coins.
The Delaware “Spitting Horse” Quarter (1999)
The first state quarter ever released has become one of the most valuable due to a distinctive error. The 1999 Delaware quarter, featuring Caesar Rodney’s historic 1776 ride, contains what collectors call the “Spitting Horse” error. This unusual mint mistake appears as a line extending from the horse’s mouth, creating the appearance of the horse spitting. In pristine condition, these error coins can command astronomical prices, with some estimates reaching $150 million.
Wisconsin’s “Extra Leaf” Quarter (2004)
The Wisconsin quarter, featuring iconic state symbols including a cow, cheese wheel, and corn stalk, became famous for its “Extra Leaf” error. This mistake resulted in an additional leaf appearing on the corn stalk, with two distinct variants: a high extra leaf and a low extra leaf. These error coins have become highly sought after by collectors, with values significantly higher than regular Wisconsin quarters.
Kansas “In God We Rust” Quarter (2005)
Perhaps the most humorous of the valuable errors is found on the 2005 Kansas quarter. Due to a grease-filled die during minting, some coins display “In God We Rust” instead of “In God We Trust.” This error has captured collectors’ imagination and created a substantial market for these unique quarters.
Other Valuable State Quarter Errors
Several other state quarters contain valuable errors worth noting:
- Connecticut (1999): Broad strike errors worth over $1,000
- New Hampshire (2000): Die crack errors valued at over $500
- Minnesota (2005): Extra tree errors fetching over $1,000
- Georgia (1999): Missing mint mark errors worth over $700
Understanding the Value
The extraordinary value of these error quarters stems from several factors:
- Rarity: Most mint errors are caught during quality control, making the few that escape into circulation extremely rare.
- Historical Significance: As part of the State Quarters program, these coins represent important aspects of each state’s heritage.
- Collector Interest: The unique nature of these errors, combined with the popularity of the State Quarters program, drives strong collector demand.
