The 2006-S North Dakota Silver States Quarter Dollar is worth anywhere from $5 in lightly circulated condition to over $20 or more in pristine proof grades — and if you’ve found one in a old collection or coin roll, it might be more special than you think. This guide will walk you through exactly what makes this coin valuable and how to figure out what yours is worth.
What Is the 2006-S North Dakota Silver Proof Quarter?
The 2006-S North Dakota quarter is part of the U.S. Mint’s 50 State Quarters Program, which ran from 1999 to 2008. The “S” mintmark means it was struck at the San Francisco Mint — and when it carries the silver designation, that means it’s composed of 90% silver rather than the standard copper-nickel clad used in everyday circulation coins.
These silver proof quarters were never released into general circulation. They were sold directly by the U.S. Mint in special Silver Proof Sets aimed at collectors. So if you’ve got one, it didn’t come from pocket change — it came from a coin set, likely passed down or found in someone’s collection.
The reverse design features North Dakota’s iconic landscape — American bison grazing near the Badlands — representing the state’s natural heritage. It’s one of the more striking designs in the entire State Quarters series.

2006-S North Dakota Silver Quarter Value by Grade
The value of your 2006-S North Dakota Silver Quarter depends heavily on its grade — meaning its physical condition. Proof coins are graded differently than circulation coins. They’re graded on the PR (Proof) scale from PR60 to the perfect PR70.
Most 2006-S Silver Proof quarters you’ll encounter will fall in the PR65 to PR69 range. A PR65 coin shows full proof characteristics with only minor contact marks, while a PR69 represents a nearly perfect coin. The top grade, PR70, is extremely rare and commands a significant premium.
Here’s a quick value breakdown:
| Grade | Description | Estimated Value |
|---|---|---|
| PR65 | Nice proof, minor blemishes | $5 – $8 |
| PR67 | Sharp proof, minimal marks | $8 – $12 |
| PR68 | Near-gem proof | $10 – $15 |
| PR69 | Near-perfect proof | $14 – $22 |
| PR70 | Perfect proof (rare) | $40 – $80+ |

How Does the Silver Content Affect Its Worth?
Here’s something many people overlook: the 2006-S North Dakota Silver Quarter has real silver in it. Each coin contains 0.1808 troy ounces of silver. When silver spot prices are around $25 per troy ounce, the melt value alone is roughly $4.50.
That silver floor means this coin will always carry some intrinsic value, even if it’s not in the best condition. When silver prices rise, so does your coin’s base value.
This is one reason collectors and everyday coin finders alike should take these S-mint silver proofs seriously. CoinHix is a great tool for tracking real-time silver values and seeing how spot price movements affect your coin’s worth on any given day.

Is It Worth Getting Your 2006-S North Dakota Silver Quarter Graded?
If you think your coin might be a PR69 or PR70, professional grading by PCGS or NGC could absolutely be worth the cost. A certified PR70 coin from a top grading service can sell for several times the value of a raw (ungraded) example.
However, for most people who find one of these in an old proof set, submitting for grading probably won’t make financial sense unless the coin looks absolutely flawless. Grading fees typically start around $20–$30 per coin, which can eat up your profit if the coin grades lower than expected.

FAQ
Q: How do I know if my 2006-S North Dakota quarter is silver or clad?
A: Look for the “S” mintmark on the obverse (front) of the coin. If it came from a U.S. Mint Silver Proof Set, it’s 90% silver. You can also check the edge — a silver coin won’t show the orange-brown copper stripe you’d see on a clad coin. Apps like CoinHix can also help you identify the composition quickly.
Q: How many 2006-S North Dakota Silver Proof quarters were made?
A: The U.S. Mint produced approximately 1.5 million Silver Proof Sets in 2006, each containing the North Dakota silver quarter. While that sounds like a lot, most were kept by collectors and never circulated, keeping the overall quality of surviving examples quite high.
Q: Can I spend a 2006-S North Dakota Silver Quarter?
A: Technically yes — it’s legal tender worth 25 cents. But you’d be spending a coin worth at least $5 to $20+ for its silver and collector value. It’s always worth knowing what you have before spending old coins.
