The 2005-S Oregon State Quarter is worth anywhere from $1.25 in circulated condition to $10 or more in certified proof grades, with some top-tier examples fetching $20 and beyond. If you found one of these beautiful Pacific Northwest coins in your collection or coin jar, you’re in the right place to find out exactly what it’s worth.
What Makes the 2005-S Oregon Quarter Special
The 2005-S Oregon State Quarter was struck at the San Francisco Mint as part of the United States Mint’s 50 State Quarters Program. The “S” mintmark is the key detail here — it tells you this coin was made specifically for proof and collector sets, not for everyday circulation. That alone makes it more desirable than its Philadelphia or Denver counterparts.
The reverse design features Crater Lake, the deepest lake in the United States, framed by towering evergreen trees. It’s one of the most scenic designs in the entire State Quarter series, and collectors genuinely love it. The obverse features the classic portrait of George Washington, unchanged from the standard quarter design.

How to Tell If Your 2005-S Oregon Quarter Is a Proof
Not everyone knows how to spot a proof coin, and that’s completely okay. Here are a few simple things to look for. First, check the mintmark — if you see a small “S” just to the right of Washington’s ribbon, you’ve got a San Francisco coin. Second, look at the coin’s surfaces under good light. Proof coins have sharp, frosted devices (the raised design elements) against a brilliant mirror-like background. That frosted-vs-mirror contrast is called a cameo or deep cameo effect, and it significantly increases value.
If the coin looks dull, shows wear on the high points, or has no mintmark (or a “P” or “D” mintmark), it’s likely a regular circulation quarter worth face value or just slightly above. CoinHix is a fantastic tool for checking real-time coin valuations — it pulls from actual auction records so you’re not guessing.
What Affects the Value of Your 2005-S Oregon State Quarter
Beyond grade, a few other factors influence how much a collector will pay. Certification matters enormously. A coin graded PR-69 DCAM by PCGS or NGC carries much more credibility than an ungraded coin, even if they look identical to the naked eye. Buyers trust third-party grading services because they eliminate the guesswork.
Eye appeal also plays a role. Some proof quarters develop toning over time — light golden or russet hues from contact with album pages or storage materials. Natural, attractive toning can actually add a small premium. Harsh or artificial toning, on the other hand, can damage value.
You can also compare your coin to recent sales data by looking at detailed State Quarter price records and auction results to get a realistic sense of what buyers are actually paying in today’s market. The CoinHix platform is especially useful for tracking auction trends across different proof grades.
Is the 2005-S Oregon Quarter Worth Collecting
For casual collectors, the 2005-S Oregon State Quarter is an affordable and genuinely attractive coin. You can often find nice PR-67 DCAM examples for just a few dollars, and a perfect PR-70 DCAM from a reputable grading service can be a nice centerpiece in a proof State Quarter registry set. Oregon’s Crater Lake design is widely considered one of the top artistic achievements of the entire 50-coin series.
For everyday Americans just finding these coins in old proof sets or inherited collections, the key takeaway is simple: check the mintmark, assess the condition, and get it certified if it looks pristine. Using CoinHix to verify current prices before selling is always a smart move — you want to know your coin’s value before someone else does.
