The 2006-S Nebraska State Quarter is worth anywhere from $0.75 in circulated proof condition to over $45 for high-grade silver specimens.

| Coin Type (2006-S) | Condition / Grade | Estimated Value |
|---|---|---|
| Clad Proof (Copper-Nickel) | PR 65 to PR 69 | $0.75 – $5.00 |
| Clad Proof (Copper-Nickel) | Deep Cameo PR 70 | $15.00 – $25.00 |
| 90% Silver Proof | PR 65 to PR 69 | $8.00 – $15.00 |
| 90% Silver Proof | Deep Cameo PR 70 | $35.00 – $45.00+ |
Understanding the 2006-S Nebraska State Quarter Value
The Nebraska State Quarter was the 37th coin released in the 50 State Quarters Program. For many casual hunters, the search begins at the top coin identifier app to distinguish between common business strikes and the more valuable “S” mint mark variations.
The San Francisco Mint (S) exclusively produced proof coins for this series. Unlike the quarters you find in your drive-thru change, these were sold in sets directly to collectors. They feature a mirror-like field and frosted details.
If you have a 2006-S Nebraska quarter, it is either a “Clad Proof” (made of copper and nickel) or a “90% Silver Proof.” Distinguishing between these two is critical for determining value. To get an instant read on your collection, the CoinKnow app can help you analyze the luster and edges to see what you really have in your hand.

Clad vs. Silver: Why the 2006-S Nebraska Price Varies
The primary factor driving the 2006-S Nebraska States Quarter dollar value is the metal composition. Clad proofs have a copper core that is visible on the edge of the coin. Silver proofs, however, have a solid white, shiny edge and are composed of 90% silver and 10% copper.
Silver coins inherently carry more value because of their “melt” worth. Even if the coin is damaged, the silver content alone makes it worth significantly more than 25 cents. Collectors who study the 2006 quarter value data know that silver versions often double or triple the price of their clad counterparts.

| Mintage Type | Total Coins Struck | Rarity Level |

The Chimney Rock Design and Condition Grading
The reverse of the Nebraska quarter features “Chimney Rock” and a covered wagon. This design celebrates Nebraska’s role as a gateway to the West. For proof quarters, the sharpness of the wagon wheels and the texture of the rock formation are vital for grading.
A “Proof” coin is not just a condition; it is a manufacturing process. However, within the proof category, coins are graded from PR 60 to PR 70. A PR 70 represents a “perfect” coin with no visible flaws even under 5x magnification.

Most 2006-S Nebraska coins found outside of their original mint plastic cases will have tiny scratches or fingerprints. This causes the value to drop to the lower end of the spectrum. If your coin looks exceptionally flashy, it might be worth a professional appraisal.
Comparing the 2006-S Nebraska Quarter to Other State Issues
While the 2006-S Nebraska quarter is a beautiful coin, it is part of a larger set that includes Nevada, West Virginia, Colorado, and North Dakota. Comparing the Nebraska coin to others, such as the high mintage 2006 Nevada quarter, reveals that S-mint proofs almost always hold a premium over P or D mint business strikes.
The CoinKnow app is an excellent resource for comparing these values side-by-side. Investors often look for “Key Dates” in the state quarter series, and while Nebraska is not considered rare, the 90% silver proof is a staple for any serious set builder.

The market for these coins usually sees small but steady increases. As more 2006 proof sets are broken up and the coins are sold individually, the supply of pristine, original-packaging specimens decreases, which can drive up prices for top-tier grades.
| Grade Range | Clad Market Price | Silver Market Price |
|---|---|---|
| PR 60 – PR 63 | Face Value – $0.50 | $5.00 – $7.00 |
| PR 65 – PR 67 | $1.50 – $3.00 | $10.00 – $14.00 |
| PR 69 Deep Cameo | $5.00 – $8.00 | $18.00 – $22.00 |
| PR 70 Deep Cameo | $25.00+ | $45.00+ |
How to Spot a 2006-S Nebraska Error Coin
Error hunters always search for “Proof Errors,” which are extremely rare. Because the San Francisco Mint uses higher quality control for proof coins, errors like double dies or off-center strikes are much harder to find than on regular quarters from Philadelphia or Denver.
Keep an eye out for “Die Doubling” on the lettering of “NEBRASKA” or “1867.” While no major 2006-S Nebraska errors have dominated the headlines yet, thousands of collectors use cameras and magnification to find new varieties every day.
If you suspect you have found an error, compare your coin to high-resolution images. A genuine error on an S-mint proof coin can skyrocket the 2006-S Nebraska States Quarter dollar value from a few dollars to hundreds or even thousands of dollars at auction.

Final Tips for Storing Your Nebraska Quarters
Because these coins are proof strikes, they are very sensitive to the environment. Oils from your skin can leave permanent “milky” spots or fingerprints on the mirror-like surface. If you find one, handle it only by the edges.
The best way to preserve the 2006-S Nebraska State Quarter value is to keep it in a PVC-free plastic flip or a specialized coin capsule. This prevents the silver from tarnishing and protects the clad versions from scratches.
Whether you are a casual hobbyist or a dedicated numismatist, these coins offer a tangible piece of American history. Always check your change, but keep a special eye out for that “S” mint mark that marks a coin intended for collectors.
