The 1999-P New Jersey Quarter is worth anywhere from its $0.25 face value in circulated condition to over $600 in high-grade mint state. While most of the quarters you find in your pocket change are only worth spending, certain rare errors and pristine specimens can command a significant premium among collectors.

Condition	Estimated Value
Circulated (Average Wear)	$0.25
Uncirculated (MS63)	$1.00 – $3.00
Choice Uncirculated (MS65)	$10.00 – $25.00
Gem Mint State (MS67+)	$150.00 – $600.00+

History and Significance of the 1999 New Jersey Quarter

The 1999-P New Jersey State Quarter holds a special place in American numismatics as the third coin released in the ambitious 50 State Quarters Program. Struck at the Philadelphia Mint (denoted by the “P” mint mark), this coin commemorates the “Crossroads of the Revolution.” The reverse design features George Washington and his troops crossing the Delaware River, based on the famous 1851 painting by Emanuel Leutze.

If you are sorting through a jar of old change, using a top coin identifier app can help you quickly distinguish between common business strikes and potential treasures. In 1999, the U.S. Mint was still adjusting to the massive production demands of the new program, leading to various quality control issues. This makes finding a “perfect” 1999-P New Jersey quarter difficult, as most were tossed into bags and quickly scratched during transport.

For everyday Americans, the excitement of these quarters lies in their accessibility. While a typical 1999-P New Jersey Quarter is common, the historical imagery has made it a favorite for educators and casual collectors alike. When evaluating your collection, remember that the CoinKnow app can provide real-time market insights to help you decide which coins to keep and which to spend.

Determining the 1999-P New Jersey Quarter Value

The value of your 1999-P New Jersey quarter is almost entirely dependent on its grade—a professional assessment of the coin’s physical condition. Because hundreds of millions were minted, a coin that has been handled, scratched, or dirtied is typically only worth its face value of twenty-five cents. However, if you find a coin that looks like it just came off the press, you might be looking at a profit.

Collectors use a 70-point scale to determine worth. A coin in “Mint State” (MS) has no wear from circulation. For example, the 1999 New Jersey quarter auction prices for high-grade specimens show that coins graded MS67 or higher can fetch hundreds of dollars at major auction houses. Once a coin drops below MS63, the collector interest dips significantly, as these coins are still very easy to find.

To get an accurate sense of what your specific coin might bring on the market, you can check the latest 1999-P quarter value data to see how recent sales have trended. This data is vital because prices for mid-range coins can fluctuate based on supply and demand. If you’re unsure of the grade, CoinKnow offers high-resolution image comparisons to help you spot the difference between a common MS60 and a more valuable MS65.

Grade	Market Price (approx.)
MS60	$0.50
MS64	$5.00
MS66	$45.00
MS68	$1,200+

Key Design Features and Mint Marks

The obverse (front) of the 1999-P New Jersey quarter features a modified portrait of George Washington. Unlike quarters minted before 1999, which had the inscriptions “United States of America” and “Quarter Dollar” on the front, the State Quarters moved these to the rim to allow more space for the reverse design. Look for the “P” mint mark to the right of Washington’s ponytail to confirm it was minted in Philadelphia.

The reverse (back) is where the “New Jersey 1787” inscription resides. It depicts the iconic scene of Washington Crossing the Delaware. The text “Crossroads of the Revolution” is featured prominently. When checking your coin, pay attention to the details on Washington’s cape and the faces of the soldiers in the boat. On high-grade coins, these details should be crisp and sharp.

Collectors should also look for signs of “luster”—that satiny, cartwheel-like shine that spins around the coin when you tilt it under a light. If the luster is dull or broken, the coin is likely circulated. Taking photos of these details and uploading them to CoinKnow can assist in identifying whether the strike quality is “Strong” or “Weak,” which also impacts the final 1999-P New Jersey quarter value.

Valuable Errors to Look For

While standard New Jersey quarters are common, error coins are the “hidden lottery tickets” of the pocket change world. In 1999, several errors were documented for this series. Some of the most sought-after include “Die Cracks” and “Clad Layers.” A die crack occurs when the metal stamp used to strike the coin begins to break, leaving a raised line of extra metal on the finished quarter.

Another rare find is the “Off-Center Strike,” where the coin blank was not properly aligned, resulting in a partial image. These can be worth $20 to $100 depending on how much of the design is missing. There are also “Broadstrikes,” where the coin is struck without the retaining collar, making it look slightly flatter and wider than a normal quarter.

Error Type	Description	Estimated Value
Double Die Obverse	Doubling on letters or date	$25 – $100
Spitting Eagle	Die crack looking like a line (rare on NJ)	$10 – $30
Missing Clad Layer	One side is bright copper colored	$50 – $400

Tips for Selling Your 1999-P New Jersey Quarter

If you believe you have found a valuable 1999-P New Jersey Quarter, the first rule is: do not clean it! Cleaning a coin with chemicals or even a soft cloth can leave microscopic scratches that ruin its value. Serious collectors prefer original “patina” or surface grime over a shiny, cleaned coin that has lost its original mint luster.

To get the best price, consider having your coin professionally graded by services like PCGS or NGC if you believe it is in MS67 condition or better. For lower-grade coins or minor errors, online marketplaces like eBay are often the best bet. When listing, use clear, macro photography and mention specific details about the coin’s condition.

Before selling, it is always wise to double-check recent “Sold” listings rather than “Asking” prices. Many people list coins for thousands of dollars that never actually sell. Using tools like CoinKnow helps you stay grounded in reality by showing you what buyers are actually paying in current market conditions.

FAQs

Q: Is the 1999-P New Jersey Quarter rare?

A: Generally, no. The Philadelphia Mint produced over 363 million of these quarters. However, finding one in “Perfect” (MS68 or MS69) condition is extremely rare and those specific coins are highly valuable.

Q: How can I tell if my 1999-P New Jersey Quarter is silver?

A: The “P” mint mark indicates it is a copper-nickel clad coin. Silver quarters for this year were only minted in San Francisco and bear an “S” mint mark. If you look at the edge of a “P” quarter, you will see a copper stripe; a silver coin will be solid white/silver on the edge.

Q: What is the most expensive 1999-P New Jersey Quarter ever sold?

A: High-grade specimens in MS68 condition have sold for over $600 at auction. Rare errors, like those struck on experimental planchets, can sometimes reach even higher prices, though these are incredibly difficult to find in circulation.

Q: What is the difference between the “P” and “D” New Jersey quarters?

A: The “P” stands for Philadelphia and the “D” stands for Denver. There is usually very little difference in value between the two for circulated coins, though sometimes one mint has a slightly lower mintage or better strike quality for that specific year.
