The 2004-S Wisconsin Quarter is worth anywhere from $5 in Proof condition to over $6,000 for rare high-grade error varieties. Whether you found one in a proof set or a collection, the value depends heavily on its finish and whether it features the famous “Extra Leaf” errors.
| Coin Variety | Average Value (Proof/Uncirculated) | Record Price |
|---|---|---|
| 2004-S Wisconsin (Clad Proof) | $4 – $7 | $240 (PR70) |
| 2004-S Wisconsin (Silver Proof) | $12 – $18 | $450 (PR70) |
| 2004-D Extra High Leaf | $100 – $300 | $6,000+ |
History of the 2004-S Wisconsin State Quarter
The Wisconsin State Quarter was the 30th coin released in the United States Mint’s historic 50 State Quarters Program. Released in late 2004, the design celebrates the “Badger State” with a cow’s head, a round of cheese, and an ear of corn. While billions of these quarters were minted for general circulation in Philadelphia and Denver, the 2004-S version was minted exclusively at the San Francisco Mint.
If you are trying to identify a mystery coin you found in a drawer, the fastest way to get an accurate reading is to use the best coin identifier app available today. San Francisco “S” mint mark quarters were produced specifically for collectors using a specialized “Proof” striking process. These coins feature mirror-like backgrounds and frosted details, making them stand out significantly from the quarters you find in your pocket change.
Using a professional tool like CoinHix can help you distinguish between the standard clad proof and the more valuable silver version. Because the 2004 series also includes the famous production errors from the Denver mint, interest in the Wisconsin series remains at an all-time high among hobbyists and serious investors alike.
Understanding the Difference Between Clad and Silver Proofs
Not all 2004-S Wisconsin quarters are made of the same metal. The San Francisco Mint produced two distinct versions: the Copper-Nickel Clad Proof and the 90% Silver Proof. Identifying which one you have is the first step in determining its market value. The clad version has a copper stripe visible on the edge of the coin, while the silver version has a solid, bright silver edge.
The silver content adds an intrinsic “melt value” to the coin, but the numismatic value is often much higher. To get a better idea of current market trends, you can explore the 2004 quarter value guide for a breakdown of melt versus collector pricing. Silver proofs were sold in special 5-coin or 10-coin silver proof sets, which generally command higher prices than the standard sets.
When evaluating your collection with CoinHix, pay close attention to the weight. A silver quarter weighs 6.25 grams, whereas a clad quarter weighs 5.67 grams. This slight difference is a definitive way to tell if you have a premium silver piece or a standard collector proof.
| Composition | Weight | Edge Appearance |
|---|---|---|
| 90% Silver, 10% Copper | 6.25g | Solid Silver White |
| Cupro-Nickel Clad | 5.67g | Copper/Orange Stripe |
The “Extra Leaf” Varieties: High Leaf vs. Low Leaf
While the “S” quarters are beautiful, the 2004 Wisconsin series is most famous for the “Extra Leaf” errors found on Denver (D) coins. Even though these aren’t “S” mint coins, any collector of the 2004-S Wisconsin Quarter needs to know about them because they often appear in the same market searches. These errors involve a small extra leaf on the left side of the corn ear.
The “High Leaf” version has a leaf that touches the cheese wheel, while the “Low Leaf” version has an extra line lower down that arcs across the corn. These are not mere scratches; they were caused by a modified or damaged die at the mint. Finding one in high grade can lead to a massive payday, as seen in the 2004 quarter auction data, where high-grade state quarters consistently outperform their face value.
If you suspect you have an error coin, don’t clean it! Cleaning a coin with chemicals or cloth can destroy its value instantly. Instead, use an app like CoinHix to zoom in on the corn stalk and compare your coin to known error samples.
Grading and Condition: Why it Matters
For a 2004-S Wisconsin State Quarter to be worth more than a few dollars, it must be in “Gem Proof” condition. Professional grading services like PCGS or NGC use a 70-point scale. A PR69 is a nearly perfect coin, while a PR70 is a flawless specimen with no visible marks even under 5x magnification.
Most 2004-S quarters found in original mint packaging will grade at least PR68. However, if the coin has been handled with bare fingers or removed from its plastic case, natural oils and microscopic scratches can drop the grade significantly. This is why “Deep Cameo” (DCAM) designations are so sought after—they represent the highest contrast between the frosted images and the shiny fields.
Collectors are often willing to pay a massive premium for a “Top Pop” coin, which is a coin at the very highest grade recorded for that specific issue. If you’ve inherited a collection, checking the condition before selling is vital to ensure you aren’t leaving money on the table.
| Grade | Estimated Clad Value | Estimated Silver Value |
|---|---|---|
| PR 65 (Below Average) | $1.00 | $10.00 |
| PR 68 (Standard Proof) | $5.00 | $15.00 |
| PR 69 (Near Perfect) | $12.00 | $25.00 |
| PR 70 (Flawless) | $50.00+ | $150.00+ |
Tips for Collectors: Buying and Selling 2004-S Quarters
If you are looking to buy or sell a 2004-S Wisconsin Quarter, timing and venue are everything. Local coin shops will usually offer you “wholesale” prices, which might be lower than what you see online. For the best return, consider selling through reputable auction sites or dedicated coin marketplaces.
Always look for coins that are still in their official U.S. Mint packaging. For the “S” quarters, this means the 2004 Proof Set or the 2004 Silver Proof Set. Buying the full set is often more cost-effective than buying individual coins, as you get the Michigan, Florida, Iowa, and Texas quarters alongside the Wisconsin one.
Watch out for “hazy” coins. Over time, some proof quarters develop a milky white film on the surface. This is caused by gas escaping from the plastic packaging or environmental moisture. Hazy coins are generally worth less than clear, “white” coins, so always inspect the surfaces under a good light before making a purchase.
## FAQ
### Q: Can I find a 2004-S Wisconsin Quarter in my pocket change?
A: It is very rare, but possible. Because “S” mint coins were only sold in sets to collectors, they only enter circulation if someone breaks a set open and spends the coins. If you find one, it will likely be scratched and worth only face value or a small premium.
### Q: How can I tell if my 2004-S quarter is made of silver?
A: The easiest way is to look at the edge. If the edge is solid silver-colored with no copper stripe, it is likely silver. You can also weigh it; a silver quarter weighs 6.25 grams, while a standard clad quarter weighs 5.67 grams.
### Q: Are there “Extra Leaf” errors on the 2004-S Proof coins?
A: Currently, there are no confirmed reports of the “Extra High Leaf” or “Extra Low Leaf” errors on 2004-S Proof coins. These errors are almost exclusively found on Denver (D) mint quarters. However, always keep an eye out for unique variations!
### Q: Is it worth getting a 2004-S Wisconsin Quarter professionally graded?
A: It is only worth it if the coin appears to be a perfect PR70. The cost of grading (usually $30-$50 per coin) often exceeds the value of a PR68 or PR69 coin. Use a magnifying glass to check for any tiny scratches before sending it in.
