Though few people know that some of the coins they own might be worth a fortune, coin collecting is an intriguing pastime. Originally unveiled as part of the 50 State Quarters Program from 1999 to 2008, these state quarters are among the most valued U.S. coins. Although most of these quarters are just worth 25 cents, certain rare mistake coins and special editions have sold for shockingly high values—some even exceeding $6.7 million. If you’ve been holding onto state quarters, it might be time to review your collection. We present five of the most expensive state quarters here, along with the factors that contribute to their exceptional pricing.
1. 1999-P Delaware State Quarter – Spitting Horse Error
First among the 50 State Quarters series was the Delaware state quarter, issued in 1999. It shows Caesar Rodney, a patriot who rode 80 miles (ca. 129 km) in a storm voting for freedom in 1776. But collectors have taken notice of an erroneous variation of this quarter, sometimes referred to as the “Spitting Horse.” The horse seems to be spitting because of a die fracture extending from its mouth, which causes the mistake.
The rarity and quality of this mistake quarter make it so desirable. Although several of these mistake coins have been discovered in circulation, uncirculated copies or those graded MS-68 or above may bring thousands of dollars at auction. Once, a perfect Spitting Horse quarter brought in more than $6,000. Though not the most costly state quarter, this is a fantastic illustration of how minor minting mistakes may greatly increase the value of a coin.
2. 2004-D Wisconsin State Quarter – Extra Leaf Error
Among the most well-known mistake coins in the series, the 2004 Wisconsin state quarter This quarter, symbolizing Wisconsin’s agricultural legacy, features a cow, a wheel of cheese, and an ear of corn. However, some quarters minted at the Denver Mint contain a clear flaw: an additional leaf on the corn stalk. Two recognized forms of this mistake are the “Low Leaf” and the “High Leaf” ones.
These very unusual mistake quarters have value based on demand and condition. Collectors have paid between $300 and $2,000 for well-preserved samples recently; the highest-graded specimens have sold for around $30,000. Should one of these erroneous quarters find its way into your collection, its value may be much more than twenty-five cents.
3. 1999-S Pennsylvania State Quarter – Silver Proof
Although collectors often seek its silver proof form, the 1999 Pennsylvania state quarter may not be an erroneous coin. The U.S. Mint produced proof sets for collectors, some of which were 90% silver. Although most silver proof quarters sell for a little premium over their face value, several have had wonderful auction performance because of their quality and rarity.
One outstanding silver proof cent from Pennsylvania, rated PR70 Deep Cameo, sold for about $7,000. Its restricted mintage, flawless quality, and deep, mirror-like gloss contribute to its high value. Should you have a proof set from 1999, it would be advisable to see whether it contains a high-grade silver Pennsylvania quarter, as it might be much more valuable than you would have guessed.
4. 2005-P Minnesota State Quarter – Double Die Error
Released in 2005, the Minnesota state quarter is well-known for having double die errors. This mistake results from the coin’s design being stamped twice in quite different locations, producing an obvious double effect. On the Minnesota quarter, the background woods display the double effect.
There are several variations of this doubling; hence, some are rarer than others. Values could range from $50 to more than $5,000 based on the intensity of the doubling and the state of the coin. This quarter, collectors have discovered some of the most well-preserved copies with spectacular doublings, which have sold at even higher values.
5. 2000-P South Carolina State Quarter – Off-Center Strike
Another worthwhile coin is the South Carolina state quarter, mostly because of an off-center strike mistake. The coin strikes off-target, missing, or misaligned portions of the design. Off-center mistakes range in degree; more spectacular instances are worth more.
Off-center mistakes are quite rare in state quarters; hence, the value relies on the strike’s off-center position. A South Carolina quarter valued at hundreds of dollars can have an off-center strike of 50% or more but still display the date and mintmark. For those who hunt mistakes, this coin is absolutely a must-check, as some of the best-graded examples have sold for more than $15,000.
