The 2006-S Nevada Silver State Quarter is worth anywhere from $8 in typical proof condition to over $100 for a perfect specimen graded by a professional service. If you have recently discovered one of these shiny, silver-edged coins in a collection or a gifted set, you are likely holding a piece of numismatic history that is worth significantly more than its twenty-five-cent face value.
Understanding the Silver Proof Nevada Quarter
The 2006-S Nevada Silver State Quarter is not your everyday pocket change. While the Denver and Philadelphia mints produced billions of copper-nickel clad quarters for general circulation, the San Francisco Mint struck special “Proof” versions specifically for collectors. Among these proofs, there are two types: the standard clad version and the highly coveted 90% silver version.
To determine if your coin is the silver variety, you should look at the edge of the quarter. A standard quarter will show a copper stripe, while the silver proof will have a solid, bright silver edge. These coins were originally sold as part of the 2006 Silver Proof Set. If you find one outside of its original plastic lens, it has likely been “broken out” by a collector.

Using the CoinKnow app can help you quickly identify the luster and strike quality of your coin. Because these coins were never intended to spend time in a cash register, their value depends entirely on their “State of Preservation.” A single scratch or fingerprint can significantly lower the market price. The Nevada design itself, featuring three wild mustangs and a desert sunrise, is considered one of the most beautiful in the 50 State Quarters program.

Grading and Market Prices for Silver Nevada Quarters
When looking at the 2006 Nevada quarter price data, it is important to distinguish between “Raw” coins and “Graded” coins. A raw coin is one that hasn’t been officially authenticated by a service like PCGS or NGC. Most silver Nevada quarters found by casual collectors are raw and typically sell for a steady premium based on their silver content and collector appeal.

However, if a coin is sent for professional grading and receives a “Proof 70 Deep Cameo” (PR70DCAM) rating—indicating it is flawless even under magnification—the price jumps significantly. Collectors are often willing to pay a high premium for perfection. For the everyday American who just found one, the most important factor is the silver weight. Unlike the quarters in your cup holder, this coin is made of .1808 troy ounces of pure silver.
Even if the coin has a few milk spots or minor haze, its “melt value” provides a solid floor for its price. You can use CoinKnow to track the current spot price of silver and see how it affects your coin’s base worth. This ensures you never sell a silver quarter for just twenty-five cents.
| Condition / Grade | Estimated Market Value |
|---|---|
| Ungraded / Raw Silver Proof | $8.00 – $12.00 |
| PR67 Deep Cameo (Certified) | $15.00 – $20.00 |
| PR69 Deep Cameo (Certified) | $25.00 – $35.00 |
| PR70 Deep Cameo (Perfect Grade) | $75.00 – $130.00+ |
Key Features of the 2006-S Silver Proof Design
The Nevada quarter was the 36th coin released in the 50 State Quarters program. The reverse side features a majestic trio of wild stallions, which are iconic symbols of the Silver State. Behind them, the sun rises over the desert mountains, framed by sagebrush—the state flower. The word “Nevada” is at the top, and the date “1864” (the year Nevada joined the Union) sits just below the state name.

On the “heads” or obverse side, you will find the standard portrait of George Washington. The key identifier for this specific value profile is the small “S” mint mark located to the right of Washington’s ponytail. This “S” denotes the San Francisco Mint. If you check the 2006 silver quarter value guide, you will see that the silver proof is distinct from the clad proof because of its weight. A silver quarter weighs 6.25 grams, while a standard clad quarter weighs 5.67 grams.
Collectors also look for the “Deep Cameo” effect. This is when the raised parts of the design (the horses and mountains) have a frosted, white appearance, while the flat fields of the coin are so polished they look like a black mirror. This high-contrast finish is what makes the 2006-S Nevada Silver Quarter a favorite among enthusiasts.
How to Handle and Store Your Nevada Quarter
If you believe you have a high-value coin, handling it correctly is the most important step in preserving its worth. Never touch the flat surfaces of the coin with your bare fingers. The oils in human skin are acidic and can leave permanent, ugly fingerprints on the “mirror” finish of a proof coin. Always hold the coin by its edges.

Many people find these coins in “junk silver” bins or passed down in envelopes. If the coin is already loose, the best thing you can do is place it in a PVC-free plastic flip or a hard plastic coin capsule. Keeping the coin air-tight prevents oxidation, which can turn the silver a yellowish or brownish hue over time.
If you aren’t sure whether your coin is worth the cost of professional grading, using CoinKnow can provide a baseline assessment. Generally, unless the coin is absolutely perfect, it is best kept as a beautiful part of a personal collection rather than sent off for expensive certification.
Frequently Asked Questions
Q: Is every 2006 quarter with an “S” mint mark made of silver?
A: No. The San Francisco Mint produced both copper-nickel clad proofs and 90% silver proofs in 2006. To tell them apart, look at the edge of the coin. If you see a copper stripe, it is clad. If the edge is solid silver, it is the silver version.

Q: Where can I sell my 2006-S Nevada Silver Quarter?
A: You can sell these coins to local coin shops, at coin shows, or through online marketplaces like eBay. Because they have a high silver content, many precious metal buyers will also purchase them, though you will likely get a better price from a collector than a pawn shop.
Q: How can I tell if my 2006 Nevada quarter is a “Proof” coin?
A: Proof coins are struck twice with specially polished dies, giving them a mirror-like background and very sharp details. All 2006 Nevada quarters with an “S” mint mark are proofs. Quarters with “P” or “D” mint marks were made for general circulation and have a matte finish.
Q: Why is the Nevada quarter so popular among collectors?
A: The Nevada design is often cited as one of the best in the series due to its artistic representation of the American West. The image of the wild mustangs resonates with many people, making the 90% silver version a popular “gift” coin or centerpiece for state quarter albums.
