The 2005-S Minnesota Silver Proof Quarter is worth anywhere from $5 to $15 in typical proof condition, with top-grade examples selling for $25 or more depending on quality and eye appeal. If you found one of these coins or inherited a collection that includes it, you’re holding something a little more special than your average pocket change.
What Makes the 2005-S Minnesota Quarter Different
Not every State Quarter is created equal, and the 2005-S Minnesota Silver Proof is a perfect example of that. The “S” mint mark tells you this coin was struck at the San Francisco Mint — a facility that has been producing collector-quality proof coins for decades. What really sets it apart is the silver content: these coins are made of 90% silver, giving them both numismatic and intrinsic metal value.
Regular clad State Quarters were made for everyday circulation. The Silver Proof versions, however, were sold directly to collectors in special mint sets and never intended for spending. That means most examples you come across today are in excellent condition, often still in their original packaging.
If you’re not sure whether the quarter in your hand is silver or clad, a coin identifier and value app can help you confirm the composition and get an instant value estimate right from your phone.

The Minnesota Design and Its Collector Appeal
The reverse design of the 2005 Minnesota State Quarter features the state’s iconic lakes and forests, with a loon swimming in the foreground, a pair of common loons in the background, and a classic outline of the state. The inscription reads “Land of 10,000 Lakes,” which is a proud nod to Minnesota’s natural identity.

Collectors tend to enjoy this design because it’s detailed and tells a real story about the state it represents. Among the 50 State Quarters series, Minnesota is generally considered a mid-range coin in terms of collector demand — not the rarest, but still a coin worth keeping in good condition.
The obverse, like all State Quarters, features a portrait of George Washington designed by John Flanagan, along with the date, “IN GOD WE TRUST,” and the “S” mint mark just below the date ribbon.

How to Tell If Your Coin Is Worth More
Proof coins with a strong “cameo” or “deep cameo” designation — where the raised design appears frosty white against a mirror-like background — tend to command higher prices. If your coin has that sharp contrast, it could grade PR-69 DCAM or even PR-70 DCAM, which are the most desirable and valuable versions.
CoinKnow is a great tool for home collectors who want to evaluate coins without sending them to a grading service right away. The app walks you through key factors like luster, strike sharpness, and surface preservation, so you can make an educated estimate before spending money on professional grading.
Coins that have been cleaned, wiped, or improperly stored lose value quickly. Original untouched proof coins, especially those still in their government-issued packaging, are always worth more to buyers and dealers. If your coin is loose and shows hairline scratches from cleaning, expect to see the value drop significantly below the chart values above.

Selling or Keeping Your 2005-S Minnesota Silver Quarter
If you’re thinking about selling, the best venues are eBay, coin shows, and local coin dealers. Silver proof sets from 2005 containing the Minnesota quarter often sell for $15 to $30 as a complete set, which can sometimes get you more than selling individual coins.
If you plan to keep it, store the coin in a proper coin flip or hard plastic holder away from moisture and direct sunlight. CoinKnow also includes a collection tracker so you can log your coins, monitor silver spot prices, and see how your collection grows in value over time.

Frequently Asked Questions
Q: Is the 2005-S Minnesota Quarter made of real silver?
A: Yes. The 2005-S Minnesota Proof Quarter is struck in 90% silver and 10% copper. It was sold as part of the U.S. Mint’s Silver Proof Set and was never made for circulation. Regular clad versions exist, but those have no silver content.
Q: How do I know what grade my 2005-S Minnesota Silver Quarter is?
A: Look for the sharpness of the design details, the reflectivity of the fields, and the frost on the raised devices. Coins with heavy cameo contrast and no visible marks typically grade PR-69 or higher. For a more precise answer, you can use CoinKnow to get a preliminary assessment or submit the coin to PCGS or NGC for official grading.
Q: Where is the mint mark on the 2005 Minnesota Quarter?
A: The “S” mint mark is located on the obverse (front) of the coin, just below the date and above the word “QUARTER DOLLAR.” This small letter confirms the coin was struck at the San Francisco Mint specifically for collector proof sets.
