State quarters are among the most popular coins for collectors in the U.S. Issued between 1999 and 2008, each quarter represents one of the 50 states with a unique design on the reverse.
While most of these coins are only worth 25 cents, a few rare and error versions are worth far more. If you’ve been collecting or holding on to these coins, here are seven valuable state quarters you’ll definitely want to watch for.
Delaware 1999-P
The first coin in the State Quarters Program is the 1999 Delaware quarter, featuring Caesar Rodney on horseback. Some of these coins show a die crack that makes it look like the horse is spitting.
Nicknamed the “Spitting Horse” quarter, these errors are fairly rare. If you manage to find one in uncirculated condition, it could fetch up to $20 from eager collectors.
Wisconsin 2004-D
One of the most famous state quarter errors is the 2004 Wisconsin “Extra Leaf” quarter. These coins feature an extra leaf on the corn stalk in the design — and there are two known variations: the “Extra High Leaf” and the “Extra Low Leaf.”
Uncirculated examples of these error coins have sold for as much as $3,000, making them a top priority for coin enthusiasts.
Minnesota 2005-P
The 2005 Minnesota quarter is known for its doubled die error. If you look closely at the trees to the right of the design, you might spot doubling, where the design appears twice.
These doubled die quarters are valued between $50 and $100 if uncirculated. It’s one of the more noticeable and collectible errors from the State Quarters Program.
Nevada 2006-P
Similar to Minnesota, the 2006 Nevada quarter has its own doubled die error. Look at the fine details in the lettering and parts of the design, and you might notice a faint doubling effect.
In uncirculated condition, these error coins typically sell for $30 to $50, making them a solid find for collectors.
South Carolina 2000-P
This one’s a little different. The 2000 South Carolina quarter has an error caused by an improperly annealed planchet. This results in discoloration or an unusual appearance on the coin’s surface.
Collectors value these error coins at around $200 if they’re in uncirculated condition, mainly because of their unusual look and scarcity.
Pennsylvania 1999-P
Another valuable error quarter is the 1999 Pennsylvania coin, which features a double die reverse. This is where the text and the state outline appear slightly doubled.
If you come across one of these in uncirculated condition, it could be worth up to $100 to the right buyer.
Ohio 2002-P
Last on our list is the 2002 Ohio quarter, which also features a double die reverse error. You can spot this by looking closely at the astronaut and the surrounding lettering.
These coins can command up to $300 in uncirculated condition, making them one of the higher-value errors from the State Quarters series.
