The 2006-D North Dakota State Quarter is worth anywhere from 25 cents in circulated condition to around $5 or more in uncirculated mint state — and certain high-grade examples have sold for significantly higher at auction. If you found one of these coins in your pocket change or an old collection, you’re in the right place.

What Is the 2006-D North Dakota State Quarter?
The 2006-D North Dakota State Quarter was minted at the Denver Mint as part of the U.S. Mint’s 50 State Quarters Program, which ran from 1999 to 2008. The “D” mintmark on the reverse stands for Denver, distinguishing it from the Philadelphia Mint version (2006-P). North Dakota was the 39th state to be featured in the series, and its quarter design showcases two grazing bison against a backdrop of the state’s signature badlands and a rising sun — a nod to the natural beauty and heritage of the Great Plains state.
The Denver Mint produced over 359 million of these quarters in 2006, making them fairly common in circulation. Most coins you’ll find in pocket change are well-worn and only worth face value. However, coins that were never circulated — especially those graded MS65 or higher by professional grading services like PCGS or NGC — can fetch a real premium among collectors.
How Much Is the 2006-D North Dakota Quarter Worth?
For most people, the honest answer is: not much more than face value if it’s been used. But condition is everything in coin collecting, and even a small difference in grade can mean a big jump in price.
| Condition / Grade | Estimated Value |
|---|---|
| Circulated (worn) | Face value ($0.25) |
| About Uncirculated (AU50–AU58) | $0.50 – $1.00 |
| Mint State MS63 | $1.00 – $2.00 |
| Mint State MS65 | $3.00 – $5.00 |
| Mint State MS67 or higher | $20.00 – $100.00+ |
| Proof (Deep Cameo, PR69–PR70) | $10.00 – $50.00+ |

Factors That Affect the 2006-D North Dakota Quarter’s Value
Several factors determine whether your 2006-D North Dakota State Quarter is worth more than a quarter:
Grade and condition — This is the single biggest factor. Coins with sharp details, original luster, and no contact marks or scratches are worth far more. A coin graded MS67 by PCGS can be worth 50 to 100 times its face value compared to an MS63 example.
Strike quality — Some 2006-D quarters came with exceptionally sharp strikes, and full-detail coins are more desirable to collectors.
Errors and varieties — Like all coins in the State Quarters series, some 2006-D North Dakota quarters were struck with minor errors — doubled dies, off-center strikes, or die cracks. Error coins can sometimes be worth considerably more, sometimes hundreds of dollars depending on the error type and severity.
Holder and certification — Coins graded and encapsulated by PCGS or NGC tend to sell for more than raw (ungraded) coins because buyers trust the authentication. If you think your coin is in exceptional shape, professional grading might be worth the investment.
How to Check the Current Value of Your 2006-D North Dakota Quarter
The best way to know what your specific coin is worth today is to compare it to recent sales. Coin values shift with collector demand and auction results, so a price guide from a few years ago may not reflect current market conditions.
For a quick overview of what 2006 quarters are worth across different mint marks and grades, dedicated coin value resources are a great starting point. You can also use CoinKnow to scan and look up your coin on the go — it pulls together grading information and recent price data so you’re not left guessing.
Local coin dealers, eBay completed listings, and major auction houses like Heritage Auctions are also reliable places to check real-world sale prices.
FAQ
Q: Is the 2006-D North Dakota State Quarter rare?
A: No, it’s not considered rare. Over 359 million were minted in Denver, making it one of the more common State Quarters. That said, high-grade examples (MS67 and above) are scarcer and do carry collector value.
Q: How do I know if my coin is uncirculated?
A: An uncirculated coin will have its original mint luster — a slight shine or “cartwheel” effect when you tilt it under light. There should be no wear on the high points of the design. If you’re unsure, CoinKnow can help you compare your coin’s appearance to graded examples.
Q: Where can I sell my 2006-D North Dakota State Quarter if it’s in great condition?
A: If you believe it’s MS65 or higher, consider submitting it to PCGS or NGC for grading first. Once certified, you can sell through eBay, coin shows, or major auction houses for the best price. For circulated examples, a local coin shop or online marketplace is your best bet.
