The 2006-S North Dakota Silver State Quarter is worth anywhere from $8 in typical proof condition to over $50 for high-grade specimens. While most quarters you find in your pocket are made of copper and nickel, this special silver version was minted specifically for collectors and holds a higher intrinsic and numismatic value.

Condition / Grade	Estimated Market Value
PR 65 (Standard Proof)	$8 – $12
PR 69 (Near Perfect)	$15 – $22
PR 70 (Perfect Grade)	$45 – $80+

Identifying the 2006-S North Dakota Silver State Quarter

Found a shiny quarter and wondering if you’ve hit the jackpot? If you have recently discovered an old collection or inherited some coins, the first step is identifying exactly what you have. Using a top coin identifier app can quickly tell you if your North Dakota quarter is the common version or the valuable silver proof. The 2006 North Dakota quarter features two grazing American bison in the foreground with a rugged sunset over the Badlands in the background.

The “S” mint mark located on the obverse (the “heads” side) signifies it was minted in San Francisco. However, not all “S” quarters are silver. In 2006, the U.S. Mint produced both “Clad” proofs and “Silver” proofs. To tell the difference, look at the edge of the coin. If you see a solid silver-colored stripe without any trace of copper/orange, you likely have the 90% silver version. If you aren’t sure, CoinKnow can help you distinguish between these varieties using high-resolution image recognition.

The Intrinsic Value of 90% Silver Quarters

Unlike the quarters we use at the vending machine, the 2006-S Silver North Dakota quarter is made of 90% silver and 10% copper. This means the coin has “melt value.” Even if the coin were scratched or damaged, it would still be worth its weight in silver. As of current market rates, the silver content alone makes this coin worth significantly more than its twenty-five-cent face value. For those tracking their portfolio, checking the latest market prices for 2006 state quarters is a great way to stay updated.

Collectors value these coins not just for the metal, but for the “Deep Cameo” finish. This refers to the sharp contrast between the frosted design (the bison and mountains) and the mirror-like background. Because these were sold in protective plastic sets, they often remain in beautiful condition. If you find one “in the wild” or loose in a jar, it may have lost some of its luster, but it remains a silver treasure.

Silver Content	90% Silver (.1808 troy oz)
Weight	6.25 grams (Heavier than clad)
Edge Appearance	Solid silver (No copper line)

Grading and How It Affects Your Quarter’s Worth

In the world of coin collecting, condition is everything. A 2006-S North Dakota Silver Quarter is graded on a scale from 1 to 70. Since these were proof coins, they usually start at a grade of PR 63 or higher. A “Proof 70” is considered a perfect coin with no visible flaws even under 5x magnification. The difference in price between a PR 69 and a PR 70 can be dozens of dollars. For a detailed breakdown of current 2006 quarter value guides, you should compare your coin against certified sold listings.

If you believe your coin is a perfect 70, you might consider having it “slabbed” or certified by a professional service like PCGS or NGC. However, for most everyday finds, using CoinKnow to get an instant estimate of the grade is the most cost-effective first step. It helps you decide if the coin is worth the $20-$30 fee for professional grading.

Mintage Figures and Rarity

The 2006-S Silver North Dakota quarter had a mintage of approximately 1,585,008. While 1.5 million sounds like a lot, it is a tiny fraction compared to the hundreds of millions of Philadelphia and Denver quarters minted for circulation that year. This relative scarcity is what keeps the price stable. These coins were never meant to be spent; they were sold as part of the “2006 United States Mint Silver Proof Set.”

When these sets are broken up and the coins are sold individually, they become “singles.” Collectors often buy these singles to complete a “Silver State Quarter” album. Because the 2006 set included other popular states like Nevada and Nebraska, the silver North Dakota coin remains a staple for enthusiasts of the series.

Mint Location	Mintage Type	Approximate Mintage
Philadelphia (P)	Circulation	305,800,000
Denver (D)	Circulation	359,000,000
San Francisco (S)	90% Silver Proof	1,585,008

Common Errors to Look For

Even though proof coins are made with extra care, errors can still occur. For the 2006 series, collectors look for “doubled die” errors where letters or numbers appear to have a faint ghost image. On the North Dakota quarter, check the bison’s horns or the text “North Dakota” for any signs of doubling. While silver proof errors are extremely rare, they can command prices in the hundreds or even thousands of dollars if verified.

If you notice something unusual about your coin, don’t clean it! Cleaning a coin with chemicals or cloth can permanentely damage the surface and strip away its collector value. Instead, take a high-quality photo and use CoinKnow to compare it with known error databases. An authentic error on a silver proof coin is a dream find for any hobbyist.

Where to Sell Your 2006-S Silver Quarter

If you’ve confirmed your coin is the 90% silver version and you’re ready to cash in, you have several options. For a quick sale, a local coin shop (LCS) will usually offer you the “wholesale” price, which is often close to the silver melt value or slightly above. This is the fastest way to get cash in hand.

For higher-grade coins (PR 69 or PR 70), online marketplaces like eBay or specialized numismatic auctions are better. You can reach a global audience of collectors willing to pay a premium for a specific state they need. Always check “Sold Items” rather than “Active Listings” to see what people are actually paying. This provides the most realistic expectation of what your North Dakota silver quarter is worth today.

FAQ

Q: How can I tell if my 2006-S quarter is silver or clad?

A: Check the edge of the coin. A silver quarter will be solid silver-white all the way through. A clad quarter will have a visible copper-colored stripe along the rim. Additionally, a silver quarter weighs 6.25 grams, while a clad quarter weighs only 5.67 grams.

Q: Is the 2006-P or 2006-D North Dakota quarter worth anything?

A: Most 2006-P and 2006-D quarters found in pocket change are only worth their face value of 25 cents. However, if they are in “Uncirculated” (perfect) condition, they can be worth $1 to $5 to a collector.

Q: Why does my silver quarter have a frosted look on the design?

A: This is called a “Cameo” effect. It is a result of a special minting process used for proof coins where the dies are polished and sandblasted to create a contrast between the shiny background and the matte design.

Q: Are there any 2006 North Dakota quarters worth thousands?

A: Only extremely rare errors or coins that receive a perfect PR 70 grade from a professional service tend to reach very high price points. Most silver proofs sell in the $8 to $30 range.
