The 2004-S Michigan State Quarter is worth anywhere from $1 in standard proof condition to over $100 for high-grade Deep Cameo silver specimens. Whether you found one in a collection or a mint set, its value depends heavily on the metal content and the preservation of its mirror-like finish.
| Coin Version | Condition | Estimated Value |
|---|---|---|
| 2004-S Clad Proof | PR 69 Deep Cameo | $3.00 – $5.00 |
| 2004-S Clad Proof | PR 70 Deep Cameo | $15.00 – $25.00 |
| 2004-S Silver Proof | PR 69 Deep Cameo | $12.00 – $18.00 |
| 2004-S Silver Proof | PR 70 Deep Cameo | $45.00 – $110.00 |
Identifying Your 2004-S Michigan Quarter Varieties
The Michigan State Quarter, released in 2004 as the 26th design in the 50 State Quarters Program, features an outline of the Great Lakes state. If you are using a top coin identifier app to check your pocket change, you might notice the “S” mint mark under the “In God We Trust” motto. This “S” signifies the San Francisco Mint, which exclusively produced Proof coins for collectors this year. It is important to know that these were not meant for general circulation, so if you find one in your change, it likely escaped from a broken-up proof set.
There are actually two distinct versions of the “S” mint mark quarter: the Copper-Nickel Clad version and the 90% Silver version. Distinguishing between them is the first step in determining your 2004-S Michigan state quarter value. One quick way to tell is to look at the edge of the coin. If you see a solid silver stripe, it is likely the 90% silver variety. If you see a copper stripe, it is a clad proof. For a more scientific approach, you can weigh the coin on a digital gram scale. The silver version is heavier, which is a key factor in the overall 2004 quarter price and rarity.
Many collectors use the CoinKnow app to quickly differentiate these varieties by scanning the coin’s surface. Because these coins were struck using special polished dies and planchets, they exhibit a “Deep Cameo” effect—frosted designs against a mirror-like background. These visual details are what drive the secondary market prices today.

Clad vs. Silver: 2004-S Michigan Proof Price Comparison
The material your coin is made of is the biggest price driver. In 2004, the U.S. Mint produced millions of these quarters in both compositions to satisfy collector demand. The silver version contains 0.1808 troy ounces of pure silver. Therefore, the silver Michigan quarter will always have a “floor” price determined by the current spot price of silver. Even if the coin is scratched or damaged, its melt value remains significant compared to the clad version, which is only worth its facial value if it is heavily worn.

In terms of market demand, collectors generally prefer the 90% silver sets. This preference creates a price gap that widens as the condition of the coin improves. While a clad proof might sell for a few dollars, a perfect silver proof can command a premium. To get the most accurate current market data, you should look for the Michigan quarter auction records and valuations to see what buyers are actually paying on platforms like eBay or Heritage Auctions.

Grading the 2004-S Michigan Quarter for Maximum Value
When dealing with proof coins, “grading” is everything. Professional grading services like PCGS or NGC use a 70-point scale. For the 2004-S Michigan State Quarter, a grade of PR 69 (Proof 69) is very common and usually doesn’t fetch a high price. However, a PR 70—representing a perfect coin with no visible flaws even under 5x magnification—is much rarer. The leap in value from a 69 to a 70 can be hundreds of dollars in some cases.
If you are unsure about the grade of your coin, the CoinKnow app can provide high-resolution comparisons to help you spot scratches or milk spots. Milk spots are white, cloudy residues that sometimes form on silver quarters due to the cleaning process at the Mint. These spots can significantly lower the grade and the 2004-S Michigan State quarter value. Collectors look for “Deep Cameo” (DCAM) or “Ultra Cameo” (UCAM) designations, which mean the contrast between the frosted Michigan design and the icy field is exceptionally sharp.
Why Condition and Packaging Matter for Collectors
Most 2004-S quarters are found inside original U.S. Mint cellophane or hard plastic cases. If you remove the coin from its original packaging, you risk exposing it to skin oils and environmental moisture, which can lead to toning or fingerprints. A toned coin (turning blue, gold, or purple) is sometimes desirable, but usually, proof collectors want a crystal-clear, brilliant finish. For those who find these coins “in the wild,” they are often described as “impaired proofs.”

An impaired proof is a coin that was struck as a proof but has entered circulation. It may have scratches, dullness, or “bag marks” from hitting other coins. While these are still cool to find, their value drops significantly. Usually, an impaired clad proof is worth only 25 cents, while an impaired silver proof is worth its weight in silver. Identifying these subtle differences is made easier by using digital tools like CoinKnow to track your collection’s worth over time.
| Condition Grade | Market Price (Clad) | Market Price (Silver) |
|---|---|---|
| Impaired/Circulated | $0.25 – $0.50 | $5.00 – $7.00 (Melt) |
| PR 68 Deep Cameo | $1.50 – $2.00 | $10.00 |
| PR 69 Deep Cameo | $4.00 | $15.00 |
| PR 70 Deep Cameo | $25.00 | $90.00+ |
Design Elements and the History of the Michigan Quarter
The 2004 Michigan quarter is visually striking, featuring the state’s outline and the Great Lakes system. The design reflects Michigan’s pride as the “Great Lakes State.” Designed by Donna Weaver, it was released on January 26, 2004. For everyday Americans, this coin is a reminder of the massive success of the State Quarters program, which encouraged millions of people to start looking at their change again.
When checking the value of this coin, focus on the details of the lakes and the text “Great Lakes State.” On high-value proof editions, these areas should be perfectly frosted and stand out against the background. If you notice any weird doubling in the letters or the year, you might have found an error coin. Errors in proof coins are extremely rare because of the high level of quality control at the San Francisco Mint, making any confirmed error highly valuable to specialists.

How to Sell Your 2004-S Michigan Quarter
If you’ve determined that your quarter is a high-grade silver proof, you might be wondering how to cash in. For coins worth less than $10, selling on eBay might not be worth the shipping costs and fees. In those cases, it’s often better to keep the coin as part of a larger set or sell it to a local coin shop in a bundle. However, if you have a PR 70 graded specimen, a specialized auction house or a dedicated coin marketplace is your best bet.
Before selling, always double-check the current silver spot price if you have the silver version. The intrinsic value of the metal provides a safety net for your investment. Keeping your coins in protective flips (acid-free plastic holders) will ensure that their condition doesn’t degrade while you wait for the right buyer.
| Sales Channel | Pros | Cons |
|---|---|---|
| Local Coin Shop | Immediate cash, no shipping | Lower payout (wholesale) |
| eBay | Reach more collectors | Fees and shipping risk |
| Coin Shows | Expert feedback available | Must travel to event |
Frequently Asked Questions
Q: How can I tell if my 2004-S Michigan quarter is silver without a scale?
A: Check the edge of the coin. A silver proof will have a solid, bright silver edge. A clad proof will show a distinct copper-colored stripe running through the center of the edge. Additionally, if you gently tap the coin (be careful!), the silver version has a higher-pitched, melodic ring compared to the duller thud of a clad coin.

Q: Is a 2004-P or 2004-D Michigan quarter worth anything?
A: Generally, Michigan quarters with “P” (Philadelphia) or “D” (Denver) mint marks are worth only 25 cents if they are found in circulation. However, if they are in “Uncirculated” condition (MS 65 or higher), they can be worth $1 to $5. Rare specimens in MS 68 or higher can sell for much more, but these are very hard to find in pocket change.
Q: What is the rarest 2004 Michigan quarter?
A: The rarest and most valuable is the 2004-S Silver Proof in a perfect PR 70 Deep Cameo grade. Beyond that, any coins with significant minting errors, such as a major double die or an off-center strike, would be considered extremely rare and valuable to collectors.
Q: Why does my Michigan quarter look shiny but has no “S” mint mark?
A: You likely have a high-grade business strike from the Philadelphia or Denver mint. While these aren’t proof coins, they can still be very shiny if they haven’t been touched much. These are typically worth face value unless they are in pristine, uncirculated condition.
