1999 Delaware Quarter – Worth $200,000
The 1999 Delaware Quarter is the first coin released in the State Quarters Program, and it’s become famous for a unique minting flaw. Known as the “spitting horse” error, it shows a small line of metal near the horse’s mouth, giving the appearance that the horse is spitting.
This error happened due to a die flaw during the coin’s production. Only a small number of these quarters were made with this issue, which makes them incredibly valuable. In one notable case, a collector sold the coin for $200,000.
Why It’s So Valuable:
- Early release in the program
- Rare minting error
- Limited known examples
If you have a 1999 Delaware Quarter, take a close look—you might own a highly collectible piece of American minting history.
2004 Wisconsin Quarter – Worth $1 Million
The 2004 Wisconsin Quarter might look normal at first glance, but some versions feature an extraordinary error. Known as the “Extra Leaf” variety, these quarters include an extra leaf on the corn stalk design—either pointing high or low.
This unexpected detail wasn’t part of the original design and is believed to have occurred during die polishing or damage. A coin with this error once sold for $1 million, making it one of the most valuable rare state quarters ever.
Why It’s So Valuable:
- Prominent and visible mint error
- Very few known examples
- High demand among collectors
Check your 2004 Wisconsin quarters carefully. If you spot an extra leaf, you might be holding a million-dollar coin.
1999 Connecticut Quarter – Worth $500,000
The 1999 Connecticut Quarter is best known for its beautiful design featuring the Charter Oak, but some versions are far more than just pretty. A few rare coins from this batch show signs of a “doubled die” error—a result of the coin being struck twice during minting.
The error causes parts of the text and tree image to appear slightly offset or doubled. Only a limited number of these flawed coins exist, and one has reportedly sold for $500,000 at auction.
Why It’s So Valuable:
- Classic doubled die mistake
- Hard to detect but incredibly rare
- Adds value to an otherwise common coin
If you have a Connecticut state quarter, look closely at the word “CONNECTICUT” and the tree details. A doubled design could mean a big payday.
2005 Minnesota Quarter – Worth $500,000
The 2005 Minnesota Quarter depicts a lake scene with trees and a person in a canoe. While it’s a common coin overall, a specific error version includes an “extra tree” that appears in the background, which wasn’t intended by the original design.
This error came from a misaligned die, which created a ghost-like image of a tree next to the real one. Because this type of error is difficult to replicate, these coins are now worth up to $500,000.
Why It’s So Valuable:
- Unique and visible design flaw
- Only a handful in circulation
- Popular among error coin collectors
Flip over any 2005 Minnesota quarters you find and check the tree line—an extra tree could mean an extra fortune.
2000 South Carolina Quarter – Worth $150,000
The 2000 South Carolina Quarter includes images of the state bird, flower, and tree. While the standard design is already detailed, certain error versions are known to show signs of a “double-strike” minting error. This occurs when the coin is struck more than once, slightly off-position.
The result is a noticeable misalignment of the features on the reverse side. These flawed coins are extremely rare, and one has sold for $150,000.
Why It’s So Valuable:
- Striking error not often seen in circulation
- Only a few discovered
- Appeals to collectors of unique coin strikes
Take a close look at any 2000 South Carolina quarters in your stash. A faint second strike could put serious money in your pocket.
