Understanding the San Francisco Minted Nevada Quarter
If you’ve recently looked through a collection or found a shiny quarter with an “S” mint mark, you’re holding a piece of the United States Mint’s “50 State Quarters” program. The Nevada quarter was the 36th coin released in this historic series, celebrating the “Silver State.” To accurately identify your find, you might want to use a top coin identifier app to ensure you aren’t overlooking any rare varieties.
Unlike the quarters minted in Philadelphia (P) or Denver (D) for general circulation, the “S” mint mark indicates the coin was struck at the San Francisco Mint. These are “Proof” coins, specifically made for collectors. They feature a mirror-like finish and sharp details.
If you are unsure whether your coin is a standard strike or a proof, the CoinKnow app can help you distinguish between the different finishes by analyzing the luster and strike quality. Knowing exactly what you have is the first step in determining if you’ve found a common pocket piece or a collector’s treasure.

Clad vs. Silver: Which Nevada Proof Do You Have?
In 2006, the San Francisco Mint produced two distinct types of Nevada quarters: the Copper-Nickel Clad version and the 90% Silver version. Distinguishing between these two is vital because the silver content alone gives the latter a higher baseline value.
The Clad version has a copper core, which you can usually see by looking at the edge of the coin. If you see a strip of orange/brown, it is clad. If the edge is solid silver-white, you likely have the silver proof.

Checking the weight is another way to tell. A standard clad quarter weighs 5.67 grams, while a 90% silver quarter weighs 6.25 grams. Many collectors use CoinKnow to log their different versions and keep track of their bullion value versus their numismatic value. You can find detailed 2006 quarter value assessment data to see how these two versions compare in today’s market.
| Feature | Clad Proof (S) | Silver Proof (S) |
|---|---|---|
| Composition | 8.33% Nickel, Balance Copper | 90% Silver, 10% Copper |
| Edge Appearance | Visible Copper Stripe | Solid Silver/White Color |
| Mint Mark | S | S |
Grading the 2006-S Nevada Quarter
Value is almost entirely dependent on the “Grade” or the condition of the coin. Because proof coins were sold in protective plastic sets, many remain in near-perfect condition. However, even the slightest scratch or “haze” on the surface can drop the price significantly.
The highest possible grade for a coin is 70. A PR70 (Proof 70) 2006-S Nevada quarter is considered “perfect” under 5x magnification. These are rare and highly sought after by registry set collectors.

Most people will find PR69 coins, which look perfect to the naked eye but have a microscopic flaw. For more information on how condition affects the bottom line, refer to the current auction prices for 2006 Nevada quarters to see what buyers are actually paying for high-grade examples.
Rare Errors and Varieties to Watch For
While major errors are rare in proof sets because of the U.S. Mint’s strict quality control, they do happen. Collectors look for “Double Dies,” where the design appears doubled, or “Clipped Planchets,” where a piece of the coin is missing from the manufacturing process.
Interestingly, most “errors” reported by beginners on 2006-S quarters are actually just environmental damage or “toning.” Toning occurs when the metal reacts with the oxygen in the air, creating a rainbow effect. Some collectors pay a premium for beautiful natural toning.

If you suspect your coin has a unique error, using CoinKnow to compare your coin against known error databases is a smart move. An authenticated error on a proof coin can turn a $5 coin into a $100+ prize overnight.
| Error Type | Visual Indicator | Rarity |
|---|---|---|
| Doubled Die | Doubling on letters or sagebrush | Very Rare |
| Improperly Annealed | Reddish or black surface tint | Rare |
The Symbolism of the Nevada Quarter Design
The Nevada quarter features a stunning design that includes three wild Mustangs, the Nevada desert sun rising behind snow-capped mountains, and a border of sagebrush—Nevada’s state flower. The banner reads “The Silver State.”
The design was created by Don Everhart and was chosen from thousands of submissions. For many everyday Americans, the beauty of the design is what makes it worth keeping, regardless of the financial value.
When you find one of these in a collection, you aren’t just looking at twenty-five cents; you are looking at a piece of American history minted during a time of great interest in numismatics. The 2006-S Nevada Proof is an essential piece for anyone trying to complete a “Silver Proof State Quarter” set.

Where to Sell Your 2006-S Nevada Quarter
If you decide that you want to cash in on your find, you have several options. For common clad proof quarters valued under $10, local coin shops or eBay are your best bets. Keep in mind that shipping costs might eat up your profit on lower-value items.
For high-grade PR70 coins or silver proofs, you might consider professional grading services like PCGS or NGC. A coin in a “slab” (a plastic case with a certified grade) sells for much more than a “raw” coin.
Before selling, always check current “Sold” listings on auction sites rather than “Asking” prices. This gives you a realistic expectation of what a buyer will actually pay. Armed with this knowledge and your research, you’ll be ready to get the best price possible for your Nevada State Quarter.
FAQ
Q: Is a 2006-S Nevada quarter rare?
A: The “S” mint mark quarters are not found in daily circulation because they were sold only in proof sets. While not “rare” in the sense that millions were made, they are considered “numismatic” items and are much harder to find than the P or D versions.

Q: How much silver is in a 2006-S Nevada quarter?
A: The 90% silver version contains approximately 0.1808 troy ounces of pure silver. Its value fluctuates based on the current spot price of silver, but it is always worth significantly more than its face value.
Q: Can I find a 2006-S quarter in my pocket change?
A: It is highly unlikely but possible. Sometimes people break open proof sets and spend them by mistake. If you find one, it is likely “impaired,” meaning it has scratches from circulation and will be worth less than a coin still in its original packaging.
Q: What is the highest price ever paid for a 2006-S Nevada Quarter?
A: Perfect PR70 Deep Cameo Silver Proofs have been known to sell for over $500 at major auctions when they are part of a highly competitive registry set collection. Most, however, sell in the $15 to $50 range.
