Ever thought that the change jingling in your pocket might be worth more than its face value? Some state quarters, due to unique errors or limited mintages, have become highly sought after by collectors, fetching prices that can make your jaw drop. Let’s dive into eight of these rare gems that have collectively amassed over $553,000 in value.

The Allure of State Quarters
Before we jump into specifics, it’s essential to understand why certain state quarters have skyrocketed in value. Introduced between 1999 and 2008, the U.S. Mint’s 50 State Quarters Program celebrated each state with unique designs. While most of these quarters are common, specific errors or anomalies have turned some into valuable collectibles.
1. 1999-P Delaware “Spitting Horse” Quarter
What’s the Buzz?
The Delaware quarter, featuring Caesar Rodney on horseback, became famous for the “spitting horse” error—a die crack near the horse’s mouth, making it appear as if it’s spitting.

Depending on its condition, this error coin can fetch between $400 and $5,000.

Similar to the Georgia quarter, some Connecticut quarters were struck on experimental planchets intended for the Sacagawea dollar.
Value Check
These rare coins have fetched significant sums at auctions, with one example selling for $4,888.
7. 2004-P Texas “Grease Strike Through Error” Quarter
A Faded Design
This error occurs when grease clogs the die, resulting in missing or faint design elements.
Value Check
Such error coins can be quite valuable, depending on the extent of the error and the coin’s condition.
8. 2005-P Kansas “In God We Rust” Quarter
A Divine Error
Some Kansas quarters are missing the “T” in “In God We Trust,” reading “In God We Rust” due to a grease-filled die.
Value Check
These coins can fetch between $100 and $1,000, depending on their condition.
Conclusion
