State quarters were a huge hit when they were released between 1999 and 2008, but did you know that some of these coins have rare errors that make them worth big money? If you have a collection of state quarters, you might want to check them for mistakes that could add serious value to your change.
Here’s a look at 8 fascinating state quarter errors, what they are, and how they affect the value of these collectible coins.
1. 2004-D Wisconsin Extra Leaf Quarter – Worth Up to $1,500
One of the most famous state quarter errors is the Wisconsin “Extra Leaf” quarter. Some quarters show an extra “low leaf” or “high leaf” on the ear of corn on the reverse side.
How It Affects Value:
- Low Leaf Error: Worth $100 to $1,000
- High Leaf Error: Worth $200 to $1,500
If you have one of these, you could be sitting on a highly valuable error coin!
2. 1999-P Delaware Spitting Horse Quarter – Worth Up to $500
This error makes it look like Caesar Rodney’s horse is spitting. The mistake was caused by a die crack on the coin.
How It Affects Value:
- In circulated condition, it’s worth $20 to $100
- In uncirculated condition, it can reach $500 or more
Check your Delaware quarters—this small flaw makes a big difference in value!
3. 2005-P Minnesota Doubled Die Quarter – Worth Up to $300
Some Minnesota quarters have a doubled die error, meaning parts of the design are duplicated slightly. You can spot this error by looking at the trees on the coin’s reverse.
How It Affects Value:
- Some minor doubled dies are worth $50 to $100
- Stronger doubling can fetch $200 to $300
If you have one, it’s worth a closer inspection!
4. 2000-P South Carolina Quarter with Misaligned Die – Worth Up to $250
Some South Carolina quarters were struck with a misaligned die, meaning the design isn’t centered properly.
How It Affects Value:
- If the misalignment is minor, it’s worth about $20
- If the design is way off-center, it can go for $200 to $250
These errors are rare but highly collectible!
5. 2002-P Tennessee Quarter Clad Layer Missing – Worth Up to $1,000
Some Tennessee quarters are missing the top clad layer, revealing the copper core underneath. This gives the coin a half-silver, half-brown look.
How It Affects Value:
- Partial missing layers: Worth $100 to $300
- Fully missing clad layer: Can reach $1,000
Coins missing their outer nickel layer are highly sought after by collectors!
6. 1999-P Connecticut Broadstrike Error – Worth Up to $500
A broadstrike error happens when a coin is struck without the collar that gives it a proper edge. This results in a wider, stretched-out quarter.
How It Affects Value:
- Common broadstrike errors are worth $50 to $200
- Uncirculated ones can sell for $300 to $500
If your Connecticut quarter looks unusually wide, it might be a broadstrike error!
7. 2007-P Wyoming Double Die Quarter – Worth Up to $200
Some Wyoming quarters feature a doubled die error, where parts of the design—like the horse and rider—appear slightly doubled.
How It Affects Value:
- Minor doubling: Worth $50 to $100
- Strong doubling: Can sell for $150 to $200
This is another quarter worth checking with a magnifying glass!
8. 2006-P Colorado Cud Error Quarter – Worth Up to $150
A cud error happens when part of the coin die breaks, leaving a raised blob of metal on the coin. Some Colorado quarters show a large cud near the mountains.
How It Affects Value:
- Small cuds: Worth $20 to $50
- Large cuds: Can go for $100 to $150
These errors are fun to find and increase in value over time!
Final Thoughts
State quarters with errors can be worth hundreds or even thousands of dollars. The Wisconsin Extra Leaf quarter and the Tennessee missing clad quarter are among the most valuable, but even smaller errors—like the Spitting Horse or doubled die quarters—can bring in extra cash.
Check your change carefully—you never know if you have a valuable quarter hiding in your pocket!
