The 2006-D North Dakota State Quarter is worth anywhere from face value to over $15 in circulated condition, and certified mint state examples can fetch $25 or more depending on grade. If you found one in your change jar or inherited a coin collection, you’re in the right place to find out exactly what you’ve got.

What Is the 2006-D North Dakota State Quarter?

The 2006-D North Dakota State Quarter was struck at the Denver Mint as part of the United States Mint’s popular 50 State Quarters Program, which ran from 1999 to 2008. The “D” mint mark stands for Denver, and it appears on the obverse (heads side) just below the date.

The reverse design features a dramatic scene of two American bison grazing on the North Dakota plains, with the iconic Badlands buttes rising in the background. This design was meant to celebrate North Dakota’s natural heritage and wide-open landscapes.

How Much Is the 2006-D North Dakota Quarter Worth in Circulated Condition?

Let’s be honest — most 2006-D North Dakota quarters you find in pocket change are going to be worth exactly 25 cents. These coins were minted in huge numbers (around 359,000,000 pieces), so circulated examples with wear are common.

That said, a coin in average circulated condition (what coin graders call “Fine” to “Extremely Fine”) might fetch 25 to 50 cents from a dealer or a fellow collector. It’s not much, but it’s still a real piece of American history.

Where things start to get more interesting is when you have a coin in near-uncirculated or fully uncirculated condition. A coin that was never spent and shows no wear can be worth $1 to $5 in raw (ungraded) uncirculated condition, and considerably more if it’s been professionally graded.

Value in Mint State — Where the Real Money Is

Coins graded by professional services like PCGS or NGC on a scale from MS-60 to MS-70 command premium prices. The higher the grade, the more collectors are willing to pay.

Errors and Varieties That Can Make Your Coin More Valuable

Most 2006-D North Dakota quarters are standard issues, but error coins are a whole different story. Mint errors happen when something goes wrong during the striking process, and collectors love them.

Some errors to look for include:

Double Die — where design elements appear doubled or blurry. Hold your coin under a loupe or magnifying glass and look at the lettering and the bison image closely.

Off-Center Strikes — where the design is not properly centered on the coin. Even a 5–10% off-center strike can double or triple the value.

Missing Clad Layer — where one of the outer copper-nickel layers didn’t bond properly, giving the coin an unusual color or texture.

If you think you’ve spotted something unusual, CoinKnow is a great tool to photograph your coin and compare it with known error varieties. Getting a second opinion before sending a coin in for grading can save you time and money.

Should You Get Your 2006-D North Dakota Quarter Graded?

This is the question most people ask, and the honest answer is: it depends. Professional grading through PCGS or NGC typically costs $20 to $40 per coin for basic services, and sometimes more. If your coin is only worth $3 to $8, it probably doesn’t make financial sense to pay for grading.

However, if you genuinely believe you have a near-perfect MS-67 or higher example — or a coin with a notable error — then professional grading is absolutely worth it. A certified MS-67 can sell for $30 to $50 or more, and an MS-68 could potentially be worth much more if it’s a top-pop coin.
