Some state quarters have transcended their face value, turning into rare collectibles worth thousands—or even hundreds of thousands—of dollars. These coins, often overlooked in loose change, can feature unique errors or varieties that boost their desirability. Here’s a look at the famous $725,000 2000-P Sacagawea Mule Quarter and other valuable state quarters you might encounter.
The $725,000 2000-P Sacagawea Mule Quarter
The 2000-P Sacagawea Mule Quarter is among the rarest and most valuable U.S. coins, with its worth estimated at up to $725,000. This coin earned the nickname “mule” because it features an unusual minting error: the obverse (front) of a Washington quarter combined with the reverse (back) design of the Sacagawea dollar. Produced at the Philadelphia Mint in 2000, only a handful of these error coins exist, making them extremely rare and valuable to collectors and investors alike.
1999 Georgia State Quarter – Off-Center and Double Die Varieties
The 1999 Georgia state quarter is another sought-after piece, with certain variations fetching up to $10,000. This coin becomes valuable when it features notable minting errors, such as off-center strikes or double-die varieties, where details appear doubled due to a misalignment during the striking process. These imperfections are relatively rare, enhancing the coin’s collectible appeal and value.
2004 Wisconsin State Quarter with Extra Leaf Error
In 2004, a minting error on the Wisconsin state quarter introduced an extra leaf on the corn stalk depicted on the coin’s reverse side. Known as the “extra leaf” error, it comes in two forms: the “high leaf” and the “low leaf.” Both varieties are valued at around $2,000 to $3,000, depending on their condition. This subtle difference has turned the Wisconsin state quarter into a popular and valuable find among collectors.
2005 Minnesota State Quarter with Double Die Extra Tree Error
The 2005 Minnesota state quarter is notable for a “double die” error that adds an extra tree on the coin’s reverse side. This coin, also known as the “extra tree” quarter, typically brings in up to $1,000 for collectors. Spotting the extra tree requires a close inspection, but the added value makes this error coin an exciting discovery for hobbyists and serious collectors.

How do I determine if I have a valuable state quarter?

Why are error quarters so valuable?
Error coins are rare due to the precision required in minting. Mistakes are usually caught early, so those that reach circulation are often in limited supply, making them more desirable to collectors.
