If you recently found one of these coins in your change jar or inherited a collection, you’re in the right place. This guide will walk you through everything you need to know about this historic coin and what it might be worth.
What Is the 1999-P Pennsylvania State Quarter?
The 1999-P Pennsylvania State Quarter was struck at the Philadelphia Mint and released as part of the United States Mint’s 50 State Quarters Program, which ran from 1999 to 2008. Pennsylvania was the second state featured in the series, following Delaware, which was honored earlier that same year. The coin features the Commonwealth’s keystone symbol, an outline of the state, and the motto “Virtue, Liberty, Independence.” For collectors and everyday coin hunters alike, the “P” mintmark on this coin identifies its Philadelphia origin.
If you’re not sure whether the coin you’re holding is this particular issue, a good coin identification app can help you confirm the date, mintmark, and variety within seconds. Tools like CoinKnow make it easy to scan your coin and get instant identification results — no coin expertise required.
How Much Is the 1999-P Pennsylvania Quarter Worth?
For most people, the 1999-P Pennsylvania State Quarter pulled from pocket change is worth face value — 25 cents. These coins were minted in enormous quantities (349,000,000 pieces), so circulated examples are extremely common. However, if your coin looks fresh and shiny with no visible wear, it may grade as uncirculated, and that changes things.
Here’s a general value breakdown by condition:
| Grade | Condition | Estimated Value |
|---|---|---|
| Circulated (G–VF) | Worn, visible use | $0.25 – $0.50 |
| Extremely Fine (EF–AU) | Light wear, sharp details | $0.50 – $1.50 |
| MS-63 | Uncirculated, minor marks | $3 – $6 |
| MS-65 | Gem uncirculated | $8 – $15 |
| MS-67 or higher | Superb gem | $20 – $100+ |

Factors That Affect the 1999-P Pennsylvania Quarter Value
Several things can push the value of your 1999-P Pennsylvania quarter higher or lower than the averages listed above.
Strike quality matters a great deal. Because Philadelphia struck nearly 350 million of these coins, quality control wasn’t perfect on every piece. Well-struck coins with full, crisp details command a premium. Surface preservation is equally important — bag marks, hairlines, and contact marks from coin-on-coin contact during shipping can reduce an otherwise uncirculated coin’s grade. Eye appeal, a somewhat subjective factor, also plays a role. Coins with bright, original luster tend to attract more competitive bidding at auction.
Error coins can also boost value significantly. If your coin shows signs of a double die, off-center strike, or clipped planchet, it may be worth considerably more than a normal example. Always inspect your coin carefully under good lighting before assuming it’s an ordinary piece.
Should You Get It Graded?
For most circulated 1999-P Pennsylvania quarters, professional grading isn’t cost-effective — the grading fee would exceed the coin’s value. However, if you believe your coin is in MS-65 condition or better, submitting it to PCGS or NGC for certification could make sense. A certified MS-67 example, for instance, can sell for multiples of what a raw coin would bring.

Tips for Finding More Valuable State Quarters
If you enjoy hunting through rolls of quarters, keep your eyes open for coins with obvious mistakes, deep cameo contrast (common on proof issues), or original mint luster. The 1999-P Pennsylvania quarter is a great starting point, but the 50 State Quarters series as a whole contains several coins that carry meaningful premiums in top grades. CoinKnow can help you build a checklist of key dates and varieties to watch for as you search through your collection.
FAQ
Q: Is the 1999-P Pennsylvania State Quarter rare?
A: No, it is not rare. With a mintage of 349,000,000, it’s one of the more common State Quarters in circulation. However, high-grade uncirculated examples in MS-67 or above are genuinely scarce and can be worth $20 to $100 or more.
Q: What does the “P” mintmark mean on my 1999 Pennsylvania quarter?
A: The “P” stands for the Philadelphia Mint, one of the two main U.S. mints that produced State Quarters. The other facility was the Denver Mint, which used a “D” mintmark. Philadelphia-minted coins are generally available in large quantities and are not considered premium over Denver issues unless in superb condition.
Q: Can I sell my 1999-P Pennsylvania quarter for more than face value?
A: In circulated condition, probably not through most channels. But if your coin grades MS-65 or higher, selling it to a coin dealer, listing it on eBay, or submitting it to auction could yield anywhere from $8 to several times that amount. Use a tool like CoinKnow to get a preliminary value estimate before approaching a buyer.
