Understanding the 1999-P New Jersey State Quarter
The New Jersey quarter was the third coin released in the historic 50 State Quarters Program, minted in 1999. Featuring General George Washington crossing the Delaware River, this coin captured the imagination of the American public. Because billions of these coins were produced to ensure everyone could collect them, finding a basic circulated version is very easy.
If you are unsure whether the coin in your hand is a standard issue or a rare gem, using a top coin identifier app can help you distinguish the subtle differences in luster and strike quality. Most people use CoinKnow to get an instant valuation by simply snapping a photo of the coin’s obverse and reverse.
The “P” mint mark on this quarter indicates it was produced at the Philadelphia Mint. At the time, the Philadelphia Mint struck over 363 million New Jersey quarters. This high mintage is the primary reason why common circulated versions are only worth their face value. However, the market for “Gem” condition coins remains competitive among registry set collectors.

Value Factors for the 1999 Philadelphia New Jersey Quarter
When determining the price of your quarter, the most critical factor is the “Grade.” Grading refers to the physical condition of the coin on a scale from 1 to 70. A coin that has been jingling in pockets for years is considered “Circulated,” while a coin that looks exactly as it did the day it left the mint is “Mint State” (MS).

Professional grading services like PCGS or NGC are often used for high-value coins, but for everyday finds, the CoinKnow app provides a reliable baseline. Most collectors look for “Full Drum” details or sharp lines on Washington’s boat to determine if a coin is worth a premium.
According to recent auction data, the 1999-P New Jersey Quarter price guides show that coins graded MS68 are incredibly rare, with only a handful known to exist. These top-tier coins are the ones that reach the hundreds or even thousands of dollars at specialized coin auctions.

Rare Errors to Look For in New Jersey Quarters
Errors are where the real money is for the average person. Sometimes the minting process goes wrong, creating unique coins that collectors crave. For the 1999-P New Jersey Quarter, several error types have been documented by the community.
One common error is the “Die Crack,” where the metal stamp used to hit the coin begins to break, leaving raised lines of metal on the coin’s surface. Another sought-after error is the “Off-Center Strike,” where the coin blank wasn’t aligned properly, resulting in a partial image.
Before you spend your quarters at the grocery store, check for anything “weird.” If you find a coin where the image is doubled (a “doubled die”) or parts of the design are missing, use CoinKnow to see if other collectors have reported similar finds. These errors can turn a 25-cent coin into a $50 or $100 treasure.

Grading Your New Jersey Quarter Like a Pro
If you want to know if your coin is worth more than face value, you need to understand the visual cues of different grades. A “Circulated” coin will have scratches, dullness, and flattened details on Washington’s hair or the soldiers in the boat.
To reach a “Mint State” grade, the coin must have “Luster,” which is that satin-like shimmer you see on brand-new coins. Even a tiny scratch visible to the naked eye can drop a coin from an MS67 to an MS64, significantly impacting the 1999 New Jersey quarter value data that collectors use to make offers.
Most 1999 quarters found today have “bag marks” from bumping into other coins at the mint. Finding a flawless “P” mint New Jersey quarter is like finding a needle in a haystack, which is why the few that exist are so valuable. High-resolution photos and comparison tools in apps like CoinKnow can help you spot these fine details.

| Feature | What to Look For |

| Strike Sharpness | Are the words “Crossroads of the Revolution” crisp? |
Where to Sell Your 1999-P New Jersey Quarter
If you believe you’ve found a high-value New Jersey quarter, you have several options for selling. For common coins worth $5 to $20, eBay is a great platform. Many collectors browse eBay looking to fill gaps in their state quarter folders.
For coins that are potentially worth hundreds of dollars, it is best to have them professionally graded by PCGS or NGC first. Once slabbed (placed in a protective plastic holder with a grade), you can sell them through major auction houses like Heritage Auctions or GreatCollections.
If you just want a quick sale or are curious, local coin shops are a good starting point. However, be aware that shops need to make a profit and may offer you 50-70% of the actual market value. Knowing your coin’s value beforehand via a pricing app ensures you get a fair deal.
FAQ
Q: Is the 1999-P New Jersey Quarter made of silver?
A: No, the standard 1999-P New Jersey Quarter is a “clad” coin, made of a copper-nickel alloy. There are silver versions of the 1999 quarter, but they were only minted in San Francisco (S mint mark) and were sold in special Proof Sets, not released into general circulation.

Q: What is the most expensive 1999-P New Jersey Quarter ever sold?
A: The record for a 1999-P New Jersey Quarter is over $1,000 for a specimen graded MS68. However, such high grades are exceptionally rare for the Philadelphia mint due to the high volume and rough handling during production.
Q: How can I tell if my New Jersey quarter is an error coin?
A: Look for anomalies like clipped edges, dramatic doubling of the words or dates, or “filled” letters where the minting die was clogged with grease. If the coin looks drastically different from a standard quarter, it might be an error.
Q: Does the “P” mint mark make it more valuable?
A: Not necessarily. The “P” just means it was made in Philadelphia. Usually, the “D” (Denver) and “P” mints have similar values for circulating coins. The “S” (San Francisco) proof coins are typically more valuable because they were made in much smaller quantities for collectors.
