The 1999-P Delaware State Quarter is worth anywhere from 25 cents in heavily worn condition to over $15 or more in uncirculated mint state — and certain high-grade examples have sold for $100 or beyond at auction. If you found one of these coins in your change jar or inherited a collection, you’re in the right place to find out exactly what it’s worth.
What Makes the 1999-P Delaware Quarter Special
The 1999-P Delaware State Quarter holds a special place in American coin history. It was the very first coin released in the United States Mint’s 50 State Quarters Program, which ran from 1999 through 2008. Delaware earned that honor because it was the first state to ratify the U.S. Constitution back in 1787 — hence its nickname, “The First State.”
The obverse (front) features the classic portrait of George Washington, while the reverse shows Caesar Rodney’s famous horseback ride. That patriotic imagery, combined with the coin’s status as the inaugural State Quarter, makes it particularly popular among collectors.
The “P” mintmark means this coin was struck at the Philadelphia Mint. Billions were produced — about 373,400,000 to be exact — so most circulated examples are easy to find. But that doesn’t mean every 1999-P Delaware quarter is worth the same. Condition is everything when it comes to value.

Error Coins That Could Be Worth a Lot More
Most 1999-P Delaware quarters are common, but there are some error coins that can dramatically increase the value of your coin. Errors happen during the minting process and are highly sought after by collectors.

Some known errors and varieties to look for include:
– Die cracks or cuds — raised lines or blobs caused by a broken die
– Off-center strikes — the design is noticeably shifted from center
– Doubled die — parts of the design appear doubled or blurry
– Clipped planchet — a chunk of the coin’s edge is missing
If your 1999-P Delaware quarter looks “off” in any way, don’t spend it. Have it evaluated by a professional coin dealer or submit it to PCGS or NGC for grading. An off-center error at 15% or more can be worth $50 to over $200. A dramatic error? Even more.

How to Get Your 1999-P Delaware Quarter Graded and Sold
If you believe your coin is in uncirculated condition, the best thing you can do is get it professionally graded. The two most respected grading services in the U.S. are PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company). A certified grade gives buyers confidence and almost always increases the sale price.
For everyday collectors, you can also sell through platforms like eBay, Heritage Auctions, or local coin shows. Circulated examples are unlikely to fetch more than face value at most shops, but gem mint state coins with strong eye appeal can attract serious bidders.
If you’re unsure where to start, CoinKnow helps you understand your coin’s grade range before you commit to a grading submission — saving you time and money.

Is the 1999-P Delaware Quarter Worth Keeping
For most people, a circulated 1999-P Delaware quarter is a sentimental piece of history rather than a financial windfall. But that doesn’t mean it’s worthless — it’s the coin that kicked off one of the most popular collecting programs in U.S. history, and it remains a must-have in any State Quarter set.
If your coin looks bright, shinier than a typical quarter, and has no visible wear on the high points of the design, it could be uncirculated and worth a small premium. And if you spot any unusual features — doubling, off-center imagery, or strange textures — set it aside immediately.
Even if your coin is only worth a quarter in monetary terms, it carries the story of Delaware’s proud place in American history. That’s something worth holding onto.
