The 2007-S Idaho State Quarter is worth anywhere from $3 to $5 in typical proof condition, but deep cameo examples graded PR70 by major grading services can sell for $20 or more. If you found one of these coins or inherited a proof set, you’re in the right place to find out exactly what it’s worth.
What Makes the 2007-S Idaho Quarter Different From the Rest
The 2007-S Idaho State Quarter was struck at the San Francisco Mint specifically for collectors. That “S” mintmark is the key detail — it means this coin was never intended for everyday pocket change. Instead, it was part of the official United States Mint Proof Sets sold directly to collectors each year.
The coin features the iconic Peregrine Falcon perched on a gloved hand, with the state outline of Idaho in the background and the motto “Esto Perpetua” (It is forever) inscribed beneath. It’s a clean, well-designed coin that many collectors genuinely enjoy owning.
Because it was produced using specially polished dies and planchets, the 2007-S has sharper details and a mirror-like finish compared to coins from the Philadelphia or Denver mints. If you’re not sure whether your coin has an “S” mintmark, use a coin identifier and value app to confirm what you have before making any decisions.
2007-S Idaho Quarter Value by Grade and Condition
Like all proof coins, the 2007-S Idaho Quarter’s value depends heavily on its grade. Proof coins are graded on the standard 70-point Sheldon scale, but collectors pay special attention to the cameo contrast — the frosted design against a mirror-like field.
Here’s a breakdown of what these coins typically sell for:
| Grade | Designation | Estimated Value |
|---|---|---|
| PR65 | Proof | $3 – $5 |
| PR67 | Proof | $5 – $8 |
| PR69 DCAM | Deep Cameo | $8 – $15 |
| PR70 DCAM | Deep Cameo (Perfect) | $20 – $40+ |
Coins that have been handled, cleaned, or scratched will fall toward the lower end of the range. A coin still in its original proof set packaging is likely to be in PR65 or better condition.

How Many 2007-S Idaho Quarters Were Made
The San Francisco Mint produced approximately 2,374,778 proof versions of the 2007-S Idaho State Quarter. That’s actually a relatively modest mintage compared to earlier State Quarter proof issues from the late 1990s and early 2000s, which often topped 3 or 4 million.
Lower mintage generally supports stronger long-term collector demand. While this coin is still affordable today, that mintage number gives it a bit more staying power than some of its more common counterparts.
Most 2007-S Idaho quarters came packaged in the annual United States Mint Proof Set, which included all five State Quarters for that year alongside the cent, nickel, dime, and half dollar. If you have the complete set in its original case, that adds a small premium to the overall value.

Should You Get Your 2007-S Idaho Quarter Graded
This is one of the most common questions collectors ask, and the honest answer is: it depends. Professional grading through PCGS or NGC costs between $20 and $40 per coin for standard service. For most 2007-S Idaho quarters worth $3 to $15, grading fees would eat up any potential profit.
However, if you believe your coin is a PR70 DCAM — meaning it has absolutely no flaws, perfect cameo contrast, and has never been touched — then professional grading could push its value to $30 or more, making it worthwhile.

Tips for Storing and Protecting Your Proof Quarter
If you want to preserve the value of your 2007-S Idaho Quarter, proper storage matters. Proof coins are sensitive to fingerprints, humidity, and air exposure. Even a tiny smudge from handling can reduce the grade and hurt the value.
Always hold proof coins by the edges, never touching the face. Store them in individual coin flips, hard plastic holders, or airtight capsules. Avoid PVC-based holders, which can cause a green chemical residue over time that damages the surface.
If your coin came in the original Mint packaging, keep it there. The original cases are acid-free and designed specifically to protect proof surfaces. Removing the coin from its original packaging almost always reduces its appeal to buyers and may lower the grade.
CoinHix also includes a collection tracker so you can log your coins, note their conditions, and monitor price trends over time — a handy tool whether you’re just starting out or building a serious collection.
