The 2007-S Idaho State Quarter is worth anywhere from $1.25 in circulated condition to over $15 or more in pristine proof grades — and if you’ve got one sitting in a drawer or coin jar, it’s worth taking a closer look. These San Francisco Mint proof coins are a favorite among collectors for their crisp detail and historical charm.
If you’re not sure whether the coin you’re holding is really a 2007-S Idaho quarter or something else entirely, a coin identification app can help you confirm the mint mark, date, and design details in seconds. This is especially handy if you’re new to coin collecting and don’t yet know what to look for.
What Is the 2007-S Idaho State Quarter?
The 2007-S Idaho State Quarter was struck at the San Francisco Mint as part of the long-running 50 State Quarters Program, which ran from 1999 to 2008. The “S” mint mark distinguishes it from quarters produced at Philadelphia (P) or Denver (D). San Francisco primarily produced proof coins during this era — meaning these were specially made for collectors, not intended for everyday circulation.
The obverse features the familiar portrait of George Washington, while the reverse showcases the state of Idaho, complete with a peregrine falcon, an outline of the state, and the motto “Esto Perpetua,” which translates to “Let it be perpetual.” Idaho was the 43rd state admitted to the Union, and the reverse design celebrates that heritage beautifully.
Because these coins were sold in proof sets directly to collectors, they were never meant to bounce around in cash registers. That’s why most 2007-S Idaho quarters you’ll find still look sharp and detailed — and why they hold more value than their face value of 25 cents.
2007-S Idaho Quarter Value by Grade
The value of a 2007-S Idaho State Quarter depends heavily on its grade and whether it’s a standard clad proof or a silver proof version. The silver proof, made from 90% silver, is considerably more valuable than the standard copper-nickel clad version.
Here’s a quick breakdown of typical market values:
| Coin Type | Grade | Estimated Value |
|---|---|---|
| Clad Proof | PR65 | $1.25 – $3.00 |
| Clad Proof | PR69 | $5.00 – $10.00 |
| Clad Proof | PR70 (DCAM) | $12.00 – $18.00+ |
| Silver Proof | PR65 | $8.00 – $12.00 |
| Silver Proof | PR70 (DCAM) | $25.00 – $40.00+ |

How to Tell If You Have the Silver Proof Version
One question that comes up a lot is: how do I know if my 2007-S Idaho quarter is silver? The easiest method is to look at the edge of the coin. A standard clad proof will show a copper-colored stripe along the edge, because it’s made of copper sandwiched between two layers of nickel. A silver proof, on the other hand, will show a uniform silver-gray edge with no copper stripe at all.
You can also check original packaging. If the coin is still in its original U.S. Mint proof set packaging, look for the words “Silver Proof Set” on the label. Silver proof sets were sold at a premium and contained all five state quarters for that year in 90% silver.

What Affects the Value of Your 2007-S Idaho Quarter
Beyond whether it’s silver or clad, a few other factors influence how much your 2007-S Idaho State Quarter is worth on today’s market:
Eye appeal and cameo contrast — Proof coins with strong “deep cameo” (DCAM) designation, where the raised design is frosty white against a mirror-like background, are the most desirable. A coin graded PR70 DCAM represents perfection and commands the highest prices.
Certification — Coins graded and slabbed by PCGS or NGC carry more trust in the marketplace and often sell for more than raw, ungraded pieces.
Silver spot price — For silver proof versions, the value is partly tied to the current price of silver. When silver prices rise, so does the floor value of your coin.

Is the 2007-S Idaho Quarter Worth Keeping?
For most people, the 2007-S Idaho State Quarter isn’t going to fund a vacation — but it’s absolutely worth more than 25 cents, and a silver proof in top condition can fetch $30 or more from the right buyer. If you have the full 2007 Silver Proof Set still in its original box, that set as a whole is worth considerably more than its individual parts.
Even if your coin isn’t silver, a well-preserved proof quarter with strong cameo contrast is a satisfying piece to add to a collection or pass along to a young collector just getting started. Use CoinKnow to catalog and value your coins effortlessly, and you might be surprised at what your collection adds up to.
