How to Identify Valuable Quarter Errors
Here’s a step-by-step checklist to help you verify your coin’s authenticity:
1. Use Magnification (10x+):
Look for extra leaves, missing letters, or unusual lines.
2. Inspect the Edge:
Check for collar cracks or rim breaks.
3. Check the Weight:
A genuine quarter should weigh about 5.67g (±0.10g).
Red Flags for Fakes:
Avoid coins with tool marks, incorrect weights, or unnatural doubling — these are often counterfeits.
Where to Find Rare Quarters
Looking to hunt your own treasure? Try these proven methods:
1. Bank Rolls:
Buy $10 rolls of quarters and check them one by one.
2. Mint Sets (1999–2008):
Some hidden gems are found in unopened Mint packaging.
3. CoinStar Reject Trays:
Yes — people have found rare quarters in CoinStar machines! 
True Story:
A lucky collector found a 2004-D Extra Leaf Wisconsin Quarter in change and sold it for $28,000!
Why Authentication Is a Must
To get top dollar, your coin must be professionally authenticated.
Coins graded by PCGS or NGC:
- Often sell for 3–5x higher
- Gain instant trust from buyers
- Cost around $25–$50 per coin
Authentication also helps confirm the exact error type, which can double your coin’s market demand.
