If you’re one of those people who casually toss spare change into a jar or glove compartment, it might be time to take a second look. A rare 1999 U.S. quarter is creating a buzz among collectors — and it could be worth up to $10,000 depending on its condition and minting error. Coin experts are urging Americans to check their pocket change, as this valuable coin might be hiding in plain sight.
What Makes the 1999 Quarter So Valuable
The quarter in question isn’t just any old coin from 1999 — it’s the Delaware State Quarter with a rare minting error. Released as part of the U.S. Mint’s State Quarters Program, the Delaware quarter was the first in the series, featuring Caesar Rodney on horseback. However, a small batch of these coins left the mint with a dramatic die crack and off-center strike, making them unique and highly desirable to collectors.

In numismatic terms, the 1999 Delaware quarter error is often called a “spitting horse” variety, named for a raised die line that appears to extend from the horse’s mouth. While ordinary Delaware quarters are worth only 25 cents, versions with this defect can fetch thousands of dollars depending on condition and grade.
According to collectors and auction records, pristine or uncirculated examples graded MS67 or higher have sold for between $3,500 and $10,000. Even circulated coins showing the error can bring in a few hundred dollars.
How to Identify the Rare 1999 Delaware Quarter
Here’s how to tell if your 1999 quarter might be valuable:
- Look for the Delaware design. The coin features Caesar Rodney riding a horse with “Delaware 1787” inscribed below.
- Check the mint mark. Coins with “P” (Philadelphia) or “D” (Denver) mint marks may both have the error, but the “P” version is more frequently reported to contain it.
- Inspect the horse’s mouth. If you notice a fine raised line or “spit mark” extending outward, you may have the “spitting horse” variety.
- Examine for off-center strikes or die cracks. Any major imperfections can significantly raise value.
If you think you have one, avoid cleaning or polishing it, as that can reduce its collector value. Instead, have it graded by a professional service such as the Professional Coin Grading Service (PCGS) or Numismatic Guaranty Company (NGC).
Where to Sell or Verify Your Coin
Collectors recommend contacting certified coin dealers or listing your coin through auction platforms that specialize in numismatics, such as Heritage Auctions or GreatCollections. You can also check estimated value through coin grading services or reputable dealers.
The U.S. Mint (www.usmint.gov) provides official background on the 50 State Quarters Program, but remember — the Mint does not buy back coins or appraise them. Always deal through a verified coin grading company or trusted auction site.
Why These Rare Quarters Matter
The 1999 Delaware quarter was part of a groundbreaking initiative by the U.S. Mint to honor each state with its own design. Over the years, some coins developed production flaws due to the immense demand, making them both rare and collectible. As the years pass, fewer of these error coins remain in circulation, which only increases their potential value.
