The 2005-S Oregon Silver State Quarter is worth anywhere from $5 in lightly circulated condition to over $20 or more in perfect mint state grades, with some proof examples fetching even higher prices among collectors. If you found one of these coins in your collection or inherited it from a family member, you’re in the right place to learn exactly what it’s worth and why.
What Makes the 2005-S Oregon Silver Quarter Special
The 2005-S Oregon State Quarter is part of the U.S. Mint’s 50 State Quarters Program, which ran from 1999 to 2008. The “S” mintmark means this coin was struck at the San Francisco Mint — and that’s a big deal. The San Francisco Mint produced these coins specifically as collector pieces, either as clad proof or 90% silver proof versions.
The silver version is the one collectors really pay attention to. Unlike quarters you’d find in everyday circulation, the 2005-S Silver Oregon Quarter contains genuine 90% silver content, making it a small but meaningful precious metal holding in addition to its numismatic value.
The Oregon design features the majestic Crater Lake, the deepest lake in the United States, surrounded by evergreen trees and a small bird in the sky. It’s one of the more visually appealing designs in the entire State Quarters series, which adds to its popularity among collectors.

If you’re unsure whether your coin is the silver version or the clad version, a coin identifier and value app can help you quickly distinguish between the two and get an estimated value based on the coin’s details and condition.
2005-S Oregon Silver Quarter Value by Grade
The value of your 2005-S Oregon Silver Quarter depends heavily on its grade and condition. Proof coins from the San Francisco Mint are graded on a scale from PR60 to PR70, with PR70 being a perfect, flawless coin. Here’s a general breakdown of current market values:

| Grade | Description | Estimated Value |
|---|---|---|
| PR65 | Gem Proof, minor blemishes | $6 – $9 |
| PR67 | Superb Gem Proof | $10 – $15 |
| PR68 | Near-perfect surfaces | $14 – $20 |
| PR69 | Nearly flawless | $18 – $28 |
| PR70 DCAM | Perfect Deep Cameo Proof | $30 – $60+ |
The “DCAM” designation stands for Deep Cameo, referring to the frosted devices (raised designs) against a mirror-like field. PR70 DCAM coins are the pinnacle of quality and command a significant premium. You can explore current market price data for State Quarter proofs to compare values across similar coins from this era.
How Many Were Minted and Why That Matters
The 2005-S Silver Oregon Quarter had a mintage of approximately 1.678 million coins. While that sounds like a lot, keep in mind that most of these were sold in annual proof sets directly to collectors — they were never intended to circulate.

This means that unlike the billions of clad quarters made at the Philadelphia and Denver Mints, the San Francisco silver proofs were always handled with care by collectors. As a result, most surviving examples are still in excellent condition today.
However, because collector-focused coins were made in relatively modest numbers compared to business strike quarters, finding a high-grade certified example (especially PR70 DCAM) can still be a challenge. That’s where the value really starts to climb.
CoinKnow is a great tool for checking mintage numbers and understanding how rarity impacts value for coins just like this one. Many collectors use it to quickly pull up historical production data and compare prices across different years in the State Quarters series.

Silver Content and Melt Value
One important factor that sets the 2005-S Oregon Silver Quarter apart from its clad counterpart is its actual precious metal content. The coin contains 90% silver and 10% copper, with a total silver weight of approximately 0.1808 troy ounces.
As silver prices fluctuate, so does the base melt value of this coin. When silver trades around $25 per troy ounce, your coin’s melt value is roughly $4.50. If silver climbs higher — which it has done in recent years — that floor price rises accordingly.
This means your 2005-S Oregon Silver Quarter will almost always be worth more than a regular quarter, even if it’s heavily worn or damaged. The silver content alone gives it a built-in minimum value that regular clad quarters simply don’t have.
For a more detailed look at how current silver prices affect the complete value breakdown for 2005 quarters including silver versions, it’s worth checking updated resources that factor in both numismatic and melt values together.

Tips for Selling or Collecting Your 2005-S Oregon Silver Quarter
If you’re thinking about selling your coin, condition is everything. A raw (ungraded) PR69 coin will typically sell for less than a professionally graded and slabbed coin with the same grade from PCGS or NGC.
For coins that appear to be in exceptional condition — particularly those with no visible marks, strong cameo contrast, and sharp details — it’s worth considering professional grading. The cost of grading is usually justified when dealing with PR69 or PR70 candidates.
On the other hand, if you’re collecting these for fun or as part of a complete State Quarters set, you don’t necessarily need to chase top grades. A nice PR67 or PR68 example from a complete silver proof set offers excellent visual appeal at a fraction of the price of a certified PR70.
CoinKnow makes it easy to track which coins you already have in your collection and which ones you’re still hunting for, whether you’re building a complete State Quarters silver proof set or just starting your coin collecting journey.

Frequently Asked Questions
Q: How do I know if my 2005-S Oregon Quarter is silver or clad?
A: The easiest way is to look at the edge of the coin. A silver quarter will show a solid silver-grey edge with no copper stripe visible. Clad quarters have a distinct reddish-copper band around the edge. You can also weigh the coin — silver quarters weigh about 6.25 grams, while clad versions weigh about 5.67 grams. Using CoinKnow or a coin identification app can also help confirm this quickly.
Q: Is the 2005-S Oregon Silver Quarter worth keeping or should I sell it?
A: If it’s in great condition with strong cameo contrast, it’s worth holding onto — especially if silver prices rise or a particularly high-grade example becomes harder to find. If you have a common PR65 or PR66 example, its value is modest but still above face value. Consider what you paid for it and whether it fits your collecting goals before deciding.
Q: Where is the best place to sell a 2005-S Oregon Silver Quarter?
A: Online auction platforms like eBay are popular choices for selling proof state quarters. For higher-grade certified coins, dealers who specialize in modern U.S. proof coinage or auction houses can get you closer to full market value. Always research recent sold prices before listing to set a realistic asking price.
