Since the launch of the 50 State Quarters Program in 1999, these coins have been cherished by collectors across the United States. While most state quarters are worth their face value, a select few have become prized collectibles due to unique errors, low mintages, or intriguing design variations. Some of these coins could turn an ordinary coin collection—or even your spare change—into a small fortune.
Let’s explore some of the most sought-after state quarters, including errors and variations that have captivated collectors and driven up their market value.
1. Delaware Quarter (1999): The Spitting Horse
The Delaware quarter features Caesar Rodney on horseback, commemorating his historic ride for American independence. However, some of these coins exhibit a “spitting horse” error, caused by a die crack near Rodney’s mouth.
- Value: Depending on condition, these coins can sell for anywhere from $100 to $20,000.
Collector’s Tip: Look closely for the die crack—it’s a small but valuable detail!
2. Wisconsin Quarter (2004): The Extra Leaf
The Wisconsin quarter highlights the state’s dairy heritage with a design featuring a cow, cheese, and an ear of corn. Certain coins were mistakenly minted with an extra leaf on the corn—either a “high leaf” or “low leaf” variation.
- Value: These coins have fetched between $300 and $10,000 at auction.
Collector’s Tip: Inspect the corn’s leaves carefully for any unusual extra details.
3. Kansas Quarter (2005): In God We Rust
The Kansas quarter, showcasing a buffalo and sunflowers, is famous for a striking mint error that causes the motto “In God We Trust” to appear as “In God We Rust.” This happens when grease clogs part of the die.
- Value: Coins with this error can be worth between $50 and $3,000.
Collector’s Tip: Check the motto carefully for any missing letters or faint impressions.
4. Minnesota Quarter (2005): The Extra Tree
The Minnesota quarter celebrates the state’s natural beauty with a depiction of lakes and forests. Some of these coins show an extra tree in the design, caused by a minting error.
- Value: These variations can fetch $150 to $5,000, depending on their condition.
Collector’s Tip: Use a magnifying glass to spot additional trees in the forest scene.
5. Connecticut Quarter (1999): Doubled-Die Error
The Connecticut quarter features the Charter Oak, an important symbol of American independence. A rare doubled-die error causes parts of the design or lettering to appear doubled.
- Value: These coins can range from $200 to $10,000, depending on their clarity and grade.
Collector’s Tip: Look for doubling in details like the branches of the tree or the coin’s text.
6. Arizona Quarter (2008): Design Alteration
The Arizona quarter, depicting the Grand Canyon and a saguaro cactus, is a favorite among collectors. Some coins feature an error where parts of the design—such as the cactus—appear missing or altered.
- Value: These coins can sell for $100 to $8,000.
Collector’s Tip: Check for unusual gaps or missing parts in the design.
7. Georgia Quarter (1999): Lettering and Design Errors
The Georgia quarter highlights the state’s iconic peach emblem and the phrase “Wisdom, Justice, Moderation.” Some coins have errors in the lettering or design, making them rare finds.
- Value: These coins can command prices between $50 and $3,500.
Collector’s Tip: Inspect the lettering for any irregularities, such as missing or doubled text.
8. Tennessee Quarter (2002): Musical Heritage
