The 2009-D Guam Quarter is worth anywhere from its face value of $0.25 in circulated condition to over $15 for high-grade Mint State specimens. While most examples you find in your pocket change are only worth a quarter, certain rare errors and high-quality strikes can fetch a premium from dedicated collectors.
| Condition / Grade | Estimated Value |
|---|---|
| Circulated (Average Wear) | $0.25 – $0.35 |
| About Uncirculated (AU50) | $0.50 – $0.85 |
| Uncirculated (MS63) | $1.50 – $3.00 |
| Gem Uncirculated (MS65+) | $10.00 – $35.00+ |
Why the 2009-D Guam Quarter is Special
The 2009 Guam Quarter was released as the third coin in the District of Columbia and U.S. Territories Quarters Program. This series followed the highly successful 50 State Quarters program. Many people aren’t aware that 2009 was a unique year for American coinage. Due to the economic recession at the time, the demand for new coinage dropped significantly. As a result, the mintage numbers for all 2009 quarters, including the Guam design from the Denver Mint (marked with a “D”), are much lower than the quarters produced in previous years.
If you are looking for an easy way to check your spare change, using a top coin identifier app can help you distinguish between common circulation strikes and rare varieties. For everyday Americans, the 2009-D Guam quarter represents a piece of Pacific island heritage. The reverse design features the outline of the island, a “Flying Proa” (a traditional sailing vessel), and a latte stone, which is a pillar used in ancient Chamorro structures. Because of the lower production numbers, these coins are harder to find in transition than quarters from 2008 or 2010, making them a “key date” for casual neighborhood collectors.

Understanding the 2009-D Guam Quarter Mintage
The Denver Mint produced exactly 43,600,000 Guam quarters in 2009. While 43 million sounds like a huge number, it is relatively small compared to the 200-400 million produced for most other states. This lower supply is the primary reason why even a standard 2009-D quarter can sometimes sell for slightly above face value in local coin shops. Collectors often look for “D” mint marks because the Denver strikes can sometimes have sharper details than their Philadelphia counterparts, though this varies from batch to batch.

When evaluating your collection, you might find that the 2009 Guam quarter worth is highly dependent on the luster and the absence of scratches. Most of these coins were snatched up by collectors immediately, so finding a truly pristine example in your pocket is rare. If you have a handful of these and aren’t sure which ones to keep, the CoinKnow app can provide instant recognition. Simply snap a photo, and the app uses AI to compare your coin’s condition against thousands of auction records to give you an estimated market price.

Grading the 2009-D Guam Quarter
To determine the real value of your 2009-D Guam quarter, you must understand grading. Professional graders use a 70-point scale. A coin graded MS60 (Mint State) has no wear but may have many “bag marks” (scratches from hitting other coins at the mint). However, if your coin is an MS67 or MS68, it is considered “Gem” quality. At this level, the value can jump from a few dollars to nearly $50 or more. This is because very few 2009-D quarters were handled carefully enough to stay in perfect condition.
For the average person at home, you can look for the “frost” on the island and the proa boat on the back of the coin. If the details of the sail look flat or smooth, the coin has been in circulation and is likely only worth its 25-cent face value. If the sail and the latte stone are sharp and shiny, you might have something special. Identifying these subtle differences is exactly what the CoinKnow app was designed for, helping you spot high-grade specimens without needing a magnifying glass.

Rare Errors to Look For in 2009 Quarters
Errors are where the real money is in modern coin collecting. While the 2009-D Guam quarter doesn’t have a famous “major” error like the 2004 Wisconsin Extra Leaf, there are several “minor” errors that can increase the value to $10 or $20. Look for “Die Cracks,” which look like raised jagged lines on the surface of the coin, or “Clipped Planchets,” where a piece of the coin appears to be missing in a curved shape.
Another common error to check for is a “Double Die.” This happens when the die used to strike the coin has a slight misalignment, causing the letters or numbers to look doubled. In the 2009 series, some collectors have reported minor doubling on the words “GUAM” or “E PLURIBUS UNUM.” While these aren’t yet worth thousands of dollars, they are highly collectible and often sell for a premium on platforms like eBay. If you think you’ve found a weird-looking letter, it’s always worth a second look before spending it at the grocery store.
| Error Type | Estimated Premium |
|---|---|
| Die Crack (Obverse or Reverse) | +$5 to +$15 |
| Off-Center Strike (5-10%) | +$10 to +$25 |
| Double Die (Minor) | +$3 to +$10 |
Collecting the Territories Series
The 2009-D Guam quarter is just one part of a six-coin set released that year. The other territories included Puerto Rico, American Samoa, the U.S. Virgin Islands, the Northern Mariana Islands, and the District of Columbia. Because all six coins had relatively low populations, many people try to collect the full “Denver and Philly” set. A complete set of 2009 quarters in Uncirculated condition can sell for $15 to $25, which is quite a jump from the $3.00 face value of the twelve coins!

If you’re starting a collection, the most important thing is storage. Never clean your coins! Cleaning a coin with chemicals or a cloth creates tiny scratches that ruin its numismatic value. Instead, place your 2009-D Guam quarters in individual cardboard flips or a coin album. This preserves the “Mint State” luster that collectors pay for. You can use the CoinKnow app to keep a digital inventory of your collection, making it easy to track the value of your Guam quarters and other territorial finds as prices fluctuate.
FAQs regarding Guam Quarter Values
Q: How can I tell if my 2009 Guam quarter is from Denver?
A: Look on the front (obverse) of the coin, to the right of George Washington’s ponytail. You will see a small letter “D.” This indicates it was minted in Denver. If you see a “P,” it was minted in Philadelphia, and an “S” means it is a proof coin from San Francisco.
Q: Are there any 2009-D quarters made of silver?
A: No, all 2009-D quarters are made of a copper-nickel clad composition. Only the “S” mint mark proof quarters from San Francisco were sometimes struck in 90% silver for special collector sets. If yours has a “D,” it is a base metal coin.

Q: Is it worth getting my 2009-D Guam quarter professionally graded?
A: Generally, it is only worth paying for professional grading (like PCGS or NGC) if the coin is in perfect condition (MS67 or higher). Since grading costs about $20-$30 per coin, the coin needs to be worth significantly more than that to make it a good investment.
Q: Where is the best place to sell my 2009-D Guam quarter?
A: For common circulated coins, you might find a buyer on eBay as part of a lot. For high-grade or error coins, consider a local coin shop or a specialized online auction. Using an app to verify the value first is a smart move before you negotiate.
