The 2009-P Guam Quarter is worth anywhere from face value up to $15 or more depending on its condition, with certain error coins fetching hundreds of dollars from serious collectors. If you found one in your change jar or inherited a coin collection, you’re in the right place — let’s break down exactly what this coin is worth and why.
What Is the 2009-P Guam Quarter?
The 2009-P Guam Quarter is part of the U.S. Mint’s District of Columbia and U.S. Territories Quarter Program, which ran during 2009. This series honored six U.S. territories and the District of Columbia, and Guam was one of the featured designs. The “P” in the name tells you it was struck at the Philadelphia Mint.
The reverse design shows the outline of Guam’s island, a traditional latte stone, and a flying proa sailboat — symbols of Guamanian culture and heritage. The obverse features the classic George Washington portrait used on all Washington quarters. About 45.2 million of these were produced at the Philadelphia Mint, making them relatively common in circulation.

2009-P Guam Quarter Value by Condition
Most 2009-P Guam Quarters you find in pocket change are worth exactly 25 cents — their face value. Dealers and collectors generally don’t pay premiums for circulated examples because so many were made.
However, coins that were never used — called “uncirculated” or “mint state” coins — are a different story. These can carry a small but real premium, especially when graded by a professional service like PCGS or NGC.
Here’s a general value table to give you a clear picture:
| Condition | Grade | Estimated Value |
|---|---|---|
| Circulated (worn) | G to EF | Face value ($0.25) |
| About Uncirculated | AU-50 to AU-58 | $1 – $3 |
| Uncirculated | MS-60 to MS-64 | $2 – $6 |
| Choice/Gem Uncirculated | MS-65 to MS-67 | $8 – $15+ |
| Error Coins | Varies | $50 – $300+ |

Error Coins That Can Make Your Quarter Valuable
Here’s where things get exciting. Some 2009-P Guam Quarters were struck with minting errors, and those coins can be worth serious money — far beyond the typical value of a regular coin.
Common errors to look for include double die obverse (where design elements appear doubled), off-center strikes (the design is shifted from center), and die cap errors. These are rare but real. A strongly off-center 2009-P Guam Quarter, for example, can sell for $100 to $300 or more depending on how dramatic the error is.
To check your coin closely, grab a 5x or 10x loupe and examine the lettering, Washington’s portrait, and the design details on the reverse. CoinHix is a great app for spotting these kinds of errors — it uses AI to analyze your coin photos and flag unusual characteristics that might indicate a minting mistake.
How to Get Your 2009-P Guam Quarter Appraised
If you think your coin might be in excellent condition or you’ve spotted something unusual, getting it properly appraised is a smart move. The two most trusted professional grading services in the U.S. are PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Corporation). They will grade, authenticate, and encapsulate your coin in a tamper-proof holder.
Grading fees typically start around $30–$50 per coin, so it only makes financial sense for coins you genuinely believe are in top condition or have an error. For everyday checking, CoinHix lets you get an instant preliminary estimate right from your phone — no mailing anything anywhere.
You can also check recent eBay sold listings to see what real buyers have actually paid for similar coins. Just search “2009-P Guam Quarter MS65” and filter by completed sales for a realistic market snapshot.
Is the 2009-P Guam Quarter Worth Keeping?
For most people, the 2009-P Guam Quarter in average circulated condition is a fun piece of American history but not a big money-maker. That said, it’s absolutely worth keeping if it’s in shiny, uncirculated condition straight from a mint roll — those can bring $5 to $15 from collectors building territorial quarter sets.
And if you ever find a genuine error coin, you could be sitting on something worth hundreds. Always take a second look before spending your coins. Tools like CoinHix make it easy for beginners to screen coins quickly and decide whether a professional appraisal is worth pursuing.
The bottom line: don’t toss this quarter back into circulation without a quick inspection. It takes 30 seconds and could save you from accidentally spending a coin worth far more than 25 cents.
