The 2017-S Effigy Mounds Quarter is worth anywhere from $1.50 in uncirculated condition to over $600 for high-grade silver proofs. While quarters found in your pocket change are usually worth face value, those with the “S” mint mark are special collector editions that always carry a premium.

Understanding the 2017-S Effigy Mounds Quarter Release
The Effigy Mounds National Monument quarter was the first release of 2017 in the United States Mint’s “America the Beautiful” series. Identifying a rare coin in your collection starts with knowing the mint mark. Most quarters you see have a “P” or “D” for Philadelphia or Denver. However, the “S” mint mark denotes the San Francisco Mint. If you are unsure what you have in your hand, using a top coin identifier and value app can help you distinguish between a common circulation strike and a collector-only “S” mint version.
The 2017-S comes in three distinct varieties: the Copper-Nickel Clad Business Strike, the Copper-Nickel Clad Proof, and the 90% Silver Proof. Unlike the P and D quarters, the 2017-S quarters were not released for general circulation. They were sold directly to collectors in rolls and bags. This means if you find one in your change, someone likely broke open a collector set to spend it!
Evaluating these coins requires a keen eye for detail. The CoinKnow app is a fantastic tool for casual collectors to quickly scan their coins and get a ballpark estimate of their worth based on recent auction data. Because these coins were handled less by the public, their condition is often much better than your average quarter.

The Value of 2017-S Business Strike Quarters
The 2017-S Business Strike quarter is unique because it was made using the same process as circulation coins but was intended for collectors. Despite this, they are relatively affordable. Most uncirculated examples sell for around $1 to $5. However, if the coin is graded by a professional service like PCGS or NGC as MS67 or higher, the price jumps significantly.
Even though these weren’t meant for the grocery store, some “S” mint quarters do circulate. If you find a 2017-S in your pocket, it is likely worth at least a small premium over its face value. For those tracking the market, the current 2017 Effigy Mounds price trends show that high-grade specimens are increasingly sought after by set builders.

When checking your coins, look for “bag marks” or scratches. Since these were shipped in bags, they often bump into each other. A pristine, scratch-free 2017-S is the goal for any serious collector.
| Grade | Business Strike (Clad) Price |
|---|---|
| MS63 | $1.25 |
| MS65 | $5.00 |
| MS67 | $25.00 |
| MS68 | $150.00+ |
2017-S Silver Proof Effigy Mounds Quarter Worth
The most valuable version of the 2017-S Effigy Mounds quarter is the Silver Proof. These were struck on planchets containing 90% silver and 10% copper. You can tell if you have one by looking at the “edge” of the coin. If you don’t see a copper-colored stripe, it is likely silver. These coins were only sold in Proof Sets.
The 90% silver content gives these coins an “intrinsic” or “melt” value, but their collector value is much higher. A perfect PR70 Deep Cameo (DCAM) silver proof can command prices over $500 in certain auction settings, though most sell in the $30-$50 range.

Identifying 2017-S Effigy Mounds Error Quarters
Errors are where the real excitement begins for everyday coin hunters. While the San Francisco Mint has high quality control, some mistakes slip through. For the Effigy Mounds design—which features mound builders’ earthworks in the shapes of animals—collectors look for specific die cracks or doubling.
Look closely at the “mounds” on the reverse of the coin. Some collectors have reported “Leaking Mounds” or small chips in the die that look like extra bumps. While not as famous as the “Wisconsin Extra Leaf,” these small errors can turn a $1 coin into a $20 or $50 coin for the right buyer.

Using CoinKnow to compare your coin against high-resolution photos of known errors is a great way to verify your find. Remember, a genuine error is much more valuable than a coin that has just been damaged in the wash.
Factors That Influence the Value of Your Quarter
The value of a 2017-S quarter depends on three main things: Mint Mark, Grade, and Type. The mint mark is found on the right side of George Washington’s portrait. The grade refers to the physical condition of the coin—how many scratches it has and how much “luster” (the original shine) remains.
The “Strike Type” is also vital. Proof coins have a mirror-like finish and frosted details, making them look almost like jewelry. If you find a coin that looks exceptionally shiny, it’s probably a proof. A regular business strike “S” mint quarter will look like a normal quarter but will be in much better condition than what you usually find in a vending machine.
Finally, market demand plays a role. Since the Effigy Mounds design represents Iowa, it is particularly popular with collectors from the Midwest. Regional demand can sometimes drive prices higher at local coin shows.

How to Sell Your 2017-S Effigy Mounds Quarter
If you’ve identified that you have a valuable 2017-S Effigy Mounds quarter, the next step is selling it. For coins worth under $10, listing them on platforms like eBay might not be worth the fees and shipping. In these cases, it’s often better to keep them as part of a personal collection or sell them in a larger lot.
For high-grade silver proofs or certified MS68 quarters, Professional coin dealers or specialty auction houses are your best bet. Always ensure your coin is protected in a plastic “flip” or capsule to prevent further damage. Touching the surface of a proof coin with your fingers can leave oils that permanently damage the finish, lowering the price.
Before selling, always get a second opinion. A quick check on a reliable pricing database or a coin identification app will ensure you don’t get underpaid for a rare variety.
FAQ
Q: Why is my 2017-S quarter worth more than a regular quarter?
A: The “S” mint mark indicates it was produced in San Francisco. Unlike “P” (Philadelphia) and “D” (Denver) quarters, these were not made for general circulation. They were produced in lower quantities specifically for collectors, making them inherently rarer.

Q: How can I tell if my 2017-S quarter is silver?

Q: Is there a 2017-S Effigy Mounds quarter in my pocket change?

A: Rare high-grade specimens of the 2017-S Silver Proof in PR70 Deep Cameo condition have sold at auction for prices ranging from $300 to over $600 depending on the current market and the grading company.
