1999-P Delaware Spitting Horse Quarter
The Delaware Spitting Horse quarter is a quirky and captivating coin. It was part of the very first batch of state quarters released in 1999 and features a die break near the horse’s mouth, creating the illusion that it is spitting.
While initially thought to be rare, more of these coins have surfaced over time, making them moderately priced at $10 to $20. However, due to its unique design flaw, this quarter remains a favorite among collectors. If you find one in your change, it’s definitely worth holding onto.
2004-D Wisconsin Extra Leaf Quarters
A true gem among error coins, the Wisconsin Extra Leaf quarters feature an additional leaf on the corn stalk, either in a high or low position. This unexpected variation was likely caused by a minting error, but its exact origin remains a mystery.
Because of its rarity and the intrigue surrounding its creation, collectors are willing to pay $50 to $65 for a well-preserved specimen. If you have a 2004 Wisconsin quarter, take a close look at the corn stalk—you might be holding a small fortune.
2005-P Minnesota Doubled Die Quarter
The Minnesota quarter from 2005 is famous for its doubled die error, which appears as extra spruce trees on the reverse side of the coin. Some variations are subtle, while others are bold and dramatic.
- Minor doubled die errors typically sell for $5 to $25.
- More dramatic versions can be worth up to $100.
This error is easy to overlook, so checking Minnesota quarters with a magnifying glass is a great idea. If you spot extra trees, you might have a valuable coin in your collection.
2009-D District of Columbia Doubled Die Quarter
Released as part of the U.S. Territories series, the 2009-D District of Columbia quarter features jazz legend Duke Ellington sitting at a piano. A unique minting error caused doubling in the letters “ELL” of his name and on the piano keys.
Because of this distinct error, collectors seek out this coin, which typically sells for around $75. While it may not be as well-known as other state quarter errors, its connection to a legendary musician adds to its desirability.
1999-S Pennsylvania and New Jersey Proof Silver Quarters
The 1999-S Pennsylvania Proof Silver and 1999-S New Jersey Proof Silver quarters are both made from 90% silver, making them more valuable than standard quarters. These were struck in limited quantities and were never intended for circulation.
- Pennsylvania Proof Silver Quarters sell for around $35.
- New Jersey Proof Silver Quarters sell for around $30.
If you come across a quarter with an “S” mintmark from the first year of the State Quarters series, check if it’s silver—it could be worth much more than pocket change.
The U.S. State Quarters program produced billions of coins, but only a handful have become truly valuable due to errors, rare mintages, and unique features. Whether it’s a die break, a doubled design, or a silver proof, these quarters have transformed from everyday change into sought-after collector’s items.
So the next time you get a handful of change, take a closer look—you just might find a hidden treasure waiting to be observed.
