| PR69 (Near Perfect) | $20.00 – $35.00 |

How to Identify the 2005-S Minnesota Silver Quarter
Finding a Minnesota quarter is common, but finding the silver version is a real win. Most quarters produced in 2005 were made of a copper-nickel clad composition for general circulation. However, the San Francisco Mint produced a limited number of “S” mint mark quarters in 90% silver. If you aren’t sure what you have, using a top coin identifier app can help you distinguish between a standard proof and the silver variety instantly.
The first thing to check is the mint mark located on the right side of George Washington’s portrait on the obverse. It must be an “S.” Next, look at the edge of the coin. A standard quarter will show a copper stripe along the rim. A silver quarter will have a solid, bright silver edge.
Finally, the weight is the ultimate giveaway. A copper-nickel quarter weighs 5.67 grams, while the silver Minnesota quarter weighs 6.25 grams. If you have a precise kitchen scale, this is the easiest way to confirm your find at home. Many collectors use the CoinKnow app to log these specific details and keep a digital inventory of their silver holdings.

The “Extra Tree” Varieties and Their Market Impact
While the silver composition makes the coin valuable, the 2005 Minnesota quarter is famous in the numismatic world for its die errors, specifically the “Extra Tree” variety. There are over 50 known versions where a manufacturing error created a “doubled die” effect on the reverse side. This looks like an extra spruce tree appearing next to the main design.
While most “Extra Tree” errors are found on the “P” and “D” mint mark coins for general circulation, they can occasionally appear on proof coins. You can find detailed numismatic valuations for state quarters that explain how these varieties can double or triple the price of a coin.

The most famous version is the “DDR-001,” where a very clear, distinct tree stands out to the right of the state map. If you think you’ve spotted an extra tree, take a high-resolution photo. Many users upload these to CoinKnow to get feedback from other enthusiasts about whether it’s a genuine error or just post-mint damage.
| Variety Type | Estimated Premium Value |
|---|---|
| Standard Silver Proof | $10 – $15 |
| Silver Proof (Deep Cameo) | $25+ |
| Minor Doubling Error | $40 – $60 |
| Major “Extra Tree” Variety | $100+ |
Why Silver Content Matters for Coin Value
The 2005-S Minnesota Silver Quarter isn’t just a collectible; it’s an investment in precious metals. Unlike everyday quarters, this specific coin contains 0.1808 troy ounces of pure silver. This means its “melt value”—the value of the metal alone—will fluctuate based on the current silver market price.
Even if the coin is scratched or damaged, it will never be worth just 25 cents. It will always be worth at least its weight in silver. However, because these were issued in special proof sets (the US Mint Silver Proof Set), they are rarely seen in bad condition. Most have been kept in protective plastic cases since they left the mint.

For those tracking their collection’s worth, understanding the current market value for 2005 quarters is essential because silver prices can change daily. Professional collectors often use CoinKnow to see live metal prices and how they affect the baseline price of their silver proof coins.
Understanding the “Proof” Finish and Grading
You might notice that the 2005-S Minnesota Silver Quarter looks different from other coins—it’s shinier, with a mirror-like background and frosted details. This is called a “Proof” finish. The San Francisco mint uses polished dies and strikes each coin at least twice to ensure every detail of the “Land of 10,000 Lakes” design pops.
The grade of the coin is what determines if it’s worth $10 or $150. Grading is done on a scale of 1 to 70. A “Perfect” PF70 coin has no visible flaws even under 5x magnification. Most coins that come directly out of a government-sealed proof set will grade at PF68 or PF69.

Getting a coin professionally graded by services like PCGS or NGC can be expensive, often costing $25-$50 per coin. It is usually only worth it if you believe your Minnesota Silver quarter is a perfect PF70 or carries a significant “Extra Tree” error. For most “everyday” finds, keeping them in an acid-free coin flip is enough to preserve their value.
| Mintage Type | Total Struck | Rarity Level |
|---|---|---|
| 2005-P (Circulation) | 239,600,000 | Very Common |
| 2005-D (Circulation) | 248,400,000 | Very Common |
| 2005-S Clad Proof | 3,344,679 | Uncommon |
| 2005-S Silver Proof | 1,678,649 | Scarce |
Where to Sell Your 2005 Minnesota Silver Quarter
If you’ve confirmed you have a silver quarter and are ready to turn it into cash, you have several options. For a quick sale, local coin shops are best, though they will typically offer you “wholesale” prices (around 60-70% of the market value) so they can make a profit on the resale.
For the highest price, online marketplaces like eBay are the way to go. Search for “2005-S Minnesota Silver Quarter” and filter by “Sold Listings” to see what people are actually paying. Avoid looking at “Active Listings,” as some sellers ask for unrealistic prices that no one actually pays.
Another great option is to attend a local coin show. This allows you to get multiple opinions from different dealers in one room. If you have a certified (graded) coin, these dealers might pay a premium to add it to their inventory. Always bring your research with you so you know exactly what your coin is worth before you start negotiating.

Summary of the Minnesota Quarter Design
The Minnesota state quarter was the 32nd coin released in the 50 State Quarters Program. The design features a scenic landscape of a lake with two people fishing, surrounded by a forest and an outline of the state. It signifies the state’s deep connection to nature and its reputation as a haven for outdoor enthusiasts.
The design was created by Charles Vickers and was chosen after a statewide competition. While millions of these designs are in circulation, the silver proof remains the “King” of the Minnesota quarters. Its beautiful Deep Cameo finish makes the trees and the fishermen stand out against the dark, mirrors of the background, making it a favorite for those who appreciate American craftsmanship.
Whether you are looking for silver content, error varieties, or a beautiful piece of history, the 2005-S Minnesota Silver quarter is a fantastic coin to own. Keep your eyes peeled on the edges of your quarters—you might just find a silver treasure hidden in plain sight.
FAQ
Q: How can I tell if my 2005 Minnesota quarter is silver without a scale?
A: The easiest way is the “tissue test” or the “edge test.” Look at the edge of the coin; if you see a copper/orange stripe, it is a standard clad coin worth 25 cents. If it is solid silver-colored, it is likely silver. Also, if you drop it on a hard table (carefully!), a silver coin will “ring” with a high pitch, while a clad coin will make a dull “thud.”

Q: Is the “Extra Tree” error only on silver quarters?
A: No, the “Extra Tree” variety is actually much more common on the quarters found in pocket change (minted in Philadelphia and Denver). While it is possible to find it on a silver proof, it is extremely rare and would be considered a major find for any collector.
Q: Should I clean my silver quarter to make it more valuable?
A: Never clean your coins! Cleaning a coin with chemicals or cloth creates microscopic scratches that can reduce the collector value by 50% or more. Coin collectors prefer “original” surfaces, even if they have a little natural toning or tarnish.
Q: Where is the mint mark on the 2005 Minnesota quarter?
A: The mint mark is on the “heads” side (obverse), just to the right of the ribbon in George Washington’s hair. You are looking for a small “S” to indicate it was minted in San Francisco, which is the only mint that produced the silver versions for that year.
