After 11 years of steady growth, the 50 State Quarters program (1999–2008) has transitioned from a nostalgic hobby into a serious market for numismatists. In 2025, collectors have moved away from collecting “raw” change and are instead paying record prices for error coins, experimental planchets, and high-grade certified specimens.
Here is the updated status of the State Quarter market for 2025–2026.
2025 Market Trends: What Has Changed?
The market for state quarters has matured significantly over the last decade. Three key trends are currently driving prices:
- The Error Boom: Interest in “In God We Rust” and “Extra Leaf” varieties is at an all-time high, with social media bringing millions of new hunters to the hobby.
- Condition Scarcity: Most uncirculated rolls have been opened and spent. Consequently, coins graded MS67 or higher by PCGS or NGC are seeing massive price jumps.
- Experimental Metals: The rarest coins in the series are “Experimental Planchet” quarters from 1999, which were struck on non-standard alloys.

How to Identify the Top 2025 Varieties
1. The Wisconsin “Extra Leaf” (2004-D)
This remains the most famous error of the 21st century. Look for a vertical line on the left side of the corn husk.
- High Leaf: The extra leaf is higher and touches the upper husk.
- Low Leaf: The extra leaf is lower and touches the cheese wheel.
- 2025 Note: Certified MS67 copies are now consistently fetching $1,500–$2,500.
2. The 1999 Experimental Planchets (P-Mint)
In 1999, the Mint tested new alloys (similar to the Sacagawea dollar). These quarters were accidentally released into circulation.
- How to Spot: They are a golden-yellow color, have a smooth edge (no ridges), and are significantly heavier (8.1gvs. 5.67g).
- Value: If you find a golden Delaware, Pennsylvania, or Connecticut quarter, it could be worth over $5,000.
3. The Kansas “In God We Rust” (2005-P)
Caused by a grease-filled die that blocked the letter “T.”
- The Hunt: Look for a 2005 Kansas quarter where the “T” in “TRUST” is completely missing or very faint.
- 2025 Trend: Clear, uncirculated versions are currently trending at $250+ on auction sites.
Collector Tips for 2026
- Check the 2008 Mintages: The final year of the program (Oklahoma, New Mexico, Arizona, Alaska, Hawaii) had some of the lowest mintages. Keep these in “brilliant uncirculated” condition.
- Silver Proofs: Every state has a 90% silver version. Look for the “S” mint mark and a solid silver edge. In 2025, these are worth $10–$40 each.
- Avoid “Plated” Quarters: Many companies sold “Gold-Plated” state quarters. These are not the rare experimental planchets and are usually only worth 25 cents to $1.
