2007-S Idaho State Quarter Value: Is Your Proof Coin Rare?
The 2007-S Idaho State Quarter is worth anywhere from $0.25 in circulated condition to over $50 in perfect Deep Cameo proof condition. While most quarters found in change are common, the “S” mint mark indicates a special collector’s edition that requires a closer look to determine its true market value.
| Condition / Grade | Estimated Value (USD) |
|---|---|
| Circulated (Spent in stores) | $0.25 – $0.50 |
| Proof (Clad) PR67-69 | $3.00 – $12.00 |
| Proof (Silver) PR69 | $15.00 – $35.00 |
| Perfect Grade PR70 DCAM | $45.00 – $90.00+ |
Identifying the 2007-S Idaho States Quarter Dollar
If you have found a 2007 Idaho quarter and noticed a small “S” under the “In God We Trust” motto, you are holding a “Proof” coin. Unlike the millions of quarters struck in Philadelphia or Denver for daily commerce, the San Francisco Mint produced these specifically for collectors. If you are unsure what version you have, using a free coin identifier app can help you distinguish between the different finishes instantly.
The Idaho quarter design features the Peregrine Falcon and an outline of the state with the motto “Esto Perpetua” (Let it be perpetual). Because these coins were sold in protective plastic sets, finding one in your pocket change usually means someone broke open a set and spent it. This significantly lowers the value. However, the high-gloss, mirror-like finish of a 2007-S coin makes it stand out from the duller “P” or “D” versions.
To get the most accurate estimate, many collectors use CoinKnow to track the current market demand. This app is incredibly useful because the market for modern state quarters fluctuates based on how many “perfect” graded coins are currently available on the retail market.
The Difference Between Clad and Silver 2007-S Idaho Quarters
One of the most important factors for the 2007-S Idaho States Quarter Dollar Value is the metal composition. In 2007, the San Francisco Mint produced two different types of proof quarters: one made of copper-nickel (clad) and one made of 90% silver. Telling the difference is crucial because the silver version is inherently more valuable due to its precious metal content.
A quick way to check is to look at the edge of the coin. If you see a solid silver stripe, it is likely the 90% silver version. If you see a copper or “sandwich” stripe, it is the standard clad proof. You can also weigh them; a clad quarter weighs 5.67 grams, while a silver quarter weighs 6.25 grams. For more detailed pricing on neighboring states released the same year, you can check the Montana state quarter value data to see how they compare.
| Composition Type | Weight | Edge Appearance |
|---|---|---|
| Copper-Nickel Clad | 5.67g | Orange/Copper Stripe |
| 90% Silver | 6.25g | Solid Silver/White |
Determining the Value of Proof 70 Deep Cameo Grades
In the world of coin collecting, condition is everything. A 2007-S Idaho Quarter that has been handled by human hands will likely grade as a “Proof 60-63,” making it a $3 coin. However, a “Perfect” PR70 Deep Cameo (DCAM) coin is a different story. These coins have no visible scratches, even under 5x magnification, and the contrast between the frosted falcon and the mirror background is sharp.
Professional grading services like PCGS or NGC are the ones who assign these top grades. If you have a coin that looks flawless, it might be worth sending in for grading. To see how these grades affect the price across the entire 2007 series, you can view this 2007 state quarter value guide to understand the premium paid for high-grade specimens.
While waiting for a formal grade, CoinKnow can provide you with recent auction results for coins in similar conditions. This prevents you from overpaying for a coin that might actually be common, or conversely, selling a rare silver proof for the price of a standard clad one.
Mintage Figures and Why They Matter for Idaho
The mintage for the 2007-S Idaho proof quarters is relatively low when compared to the hundreds of millions of Philadelphia and Denver quarters produced that year. The U.S. Mint struck approximately 2.3 million clad proofs and about 1.3 million silver proofs for the Idaho design. While a million sounds like a lot, it is a tiny fraction of the overall state quarter production.
Because these sets were sold as part of a five-coin set (including Montana, Washington, Wyoming, and Utah), individual Idaho halves of the set are often sold separately by dealers today. If you have the original packaging (the “Lens” or blue/red box), your coin will typically be worth more than a “raw” or loose coin that has been touched.
| Mint Mark | Mintage Type | Quantity Produced |
|---|---|---|
| 2007-P | Business Strike | 294,600,000 |
| 2007-D | Business Strike | 286,800,000 |
| 2007-S | Clad Proof | 2,374,778 |
| 2007-S | Silver Proof | 1,313,481 |
Common Errors on 2007 Idaho Quarters
While errors on proof coins are extremely rare because of the intense quality control at the San Francisco Mint, they can happen. Collectors are always on the lookout for doubled dies, where the lettering or the falcon image appears slightly “shadowed” or doubled. On a proof coin, an error like this could potentially skyrocket the value into the hundreds or even thousands of dollars.
Other errors to look for include “Clad Layers” missing or “Off-Center” strikes. If you notice something odd about your Idaho quarter, do not clean it! Cleaning a coin destroys its numismatic value. Instead, use an app like CoinKnow to zoom in and compare your coin with known error varieties. It is better to have a dirty, rare error than a shiny, ruined one.
For the everyday American, most 2007-S Idaho quarters will be worth their silver melt value or a small collector premium. If you find one in a drawer, keep it in a soft flip or a plastic capsule to preserve whatever mirror finish it still has. These are beautiful pieces of American history that represent the unique geography of the Gem State.
FAQ
Q: Can I find a 2007-S silver quarter in my pocket change?
A: While it is extremely rare, it does happen. This occurs when someone unknowingly spends a silver proof set. If you find one that sounds higher-pitched than a normal quarter when dropped on a table and has a solid silver edge, check it immediately!
Q: Why is my 2007 Idaho quarter “gold” colored?
A: The U.S. Mint never released gold Idaho quarters. If yours is gold, it has likely been plated by a private company for a novelty set. These are generally worth only $0.25 to $1.00 because collectors consider the plating to be “damage.”
Q: Is the Idaho quarter more valuable than other 2007 quarters?
A: Generally, all 2007 proof quarters (Montana, Washington, Idaho, Wyoming, Utah) have similar values. However, Idaho is popular among bird enthusiasts due to the Peregrine Falcon design, which can sometimes lead to a slightly faster sale at coin shows.
Q: How can I tell if my 2007-S is “Deep Cameo”?
A: A Deep Cameo (DCAM) coin will have a heavy, white frosted look on the falcon and the state outline, making them pop against a black, mirror-like background. If the frosting is light or non-existent, it is just a standard proof.
