1. 1999‑P Delaware Quarter
The very first coin in the Statehood series, this quarter is even rarer when struck on a Sacagawea dollar experimental planchet, showing a smooth edge, heavier weight (about 8.1g), and a metallic sheen. Only a few exist—and one graded MS66 sold for nearly $6.7 million
2. 2004‑D Wisconsin “Extra Leaf”
The Extra Leaf quarter from Wisconsin is famous for showing an extra corn leaf—either a “Low” or “High” variety. In high mint-grade (MS67), specimens have sold for up to $6,000
3. 1999‑P Georgia Quarter
Similar to Delaware’s coin, the Georgia quarter was accidentally struck on a Sacagawea alloy planchet, giving it a golden or greenish hue, lacking reeded edges, and weighing more than the standard 5.67 g. One example has sold for about $10,000
4. 1999‑P Connecticut Quarter
One of the rarest coins due to its Sacagawea planchet error, the Connecticut quarter boasts a golden color, smooth edge, and heavier feel. A premium-grade MS69 coin fetched around $10,500
5. 2000‑P South Carolina Quarter
Featuring the Carolina wren and palmetto tree, this quarter is still common in circulation—but in ultra-high mint state (MS69), it becomes extremely rare. One such coin sold for approximately $8,000
Understanding Why These Quarters Are Valuable
Error & Experimental Rarity
- Sacagawea planchet errors (Delaware, Georgia, Connecticut) feature different weight, color, and lack reeding due to wrong metal composition.
- Minting errors like the Wisconsin Extra Leaf create distinct visual anomalies, boosting collectability.
Condition (Mint State Grades)
- Grades from MS66 to MS69 denote near-perfect condition: crisp design details, no wear or marks.
- These grades drastically increase value.
Limited Quantity
- Only handfuls of these coin types were produced—especially experimental and mint-error varieties—making them extremely rare.
Modern state quarters may seem ordinary, but a few rare specimens—like the Delaware experimental planchet or Wisconsin Extra Leaf—can be worth thousands, even millions.
With sharp eyes and a bit of luck, you might find a hidden treasure in your pocket. Stay observant, educate yourself on identifying traits, and you might just hold a piece of numismatic history. Happy hunting!
