History and Design of the George Rogers Clark Quarter

The 2017 George Rogers Clark National Historical Park quarter was the 40th release in the “America the Beautiful” (ATB) series. This program honors national parks and historic sites from every state and territory. This specific coin celebrates the location in Vincennes, Indiana, commemorating the crucial role General George Rogers Clark played during the American Revolution.

If you are unsure if you have a George Rogers Clark quarter or a different release from that year, using a top coin identifier app can help you distinguish between the various designs instantly. The reverse design of this coin shows George Rogers Clark leading his men through the flooded plains of the Illinois territory to attack Fort Sackville.

Collectors often look for the fine details in the muskets and the ripples in the water. To get the most accurate George Rogers Clark quarter value information, you must first verify that your coin features the “S” mint mark, located on the obverse to the right of George Washington’s ponytail. CoinKnow makes this process incredibly easy by analyzing the image and identifying the mint mark for you.

What Makes the “S” Mint Mark Special?

Most quarters you find in your pocket will have a “P” (Philadelphia) or “D” (Denver) mint mark. Coins minted in San Francisco bearing the “S” mark are typically intended for collectors. In 2017, the San Francisco Mint produced two types of “S” quarters: Copper-Nickel Clad proofs and 90% Silver proofs.

Unlike the common business-strike Philadelphia coins, which you can track via the latest 2017-P ATB quarter price data, the “S” mint coins are rarely found in general circulation. If you find an “S” quarter in your change, it was likely broken out of a proof set by mistake.

Because these coins are struck specifically for collectors, they feature a “mirror-like” finish on the flat surfaces and a frosty, matte appearance on the raised designs. This is referred to as a “Cameo” effect. Determining if your coin is the clad version or the silver version is the first step in unlocking its true market value.

Mint Mark	Mintage Type	Est. Mintage
2017-S Clad	Proof Set Only	Approx. 800,000
2017-S Silver	Silver Proof Set Only	Approx. 550,000
2017-S Circulated	NIFC (Not Intended for Circulation)	Approx. 900,000

Identifying Clad vs. Silver 2017-S Quarters

The biggest price jump for the George Rogers Clark quarter occurs between the standard clad version and the silver version. In 2017, the U.S. Mint was still using 90% silver for proof quarters. Since the price of silver fluctuates, the value of the silver proof quarter will always be higher than the clad version.

One easy way to check is to look at the edge of the coin. If you see a solid silver-colored stripe, it is likely silver. If you see a copper or brownish stripe through the center of the edge, it is a standard clad quarter. You can also use a digital scale; a silver quarter weighs 6.25 grams, while a clad quarter weighs 5.67 grams.

For a more high-tech approach, the CoinKnow app can help you categorize your collection and keep track of metal content values. It is a fantastic tool for everyday Americans who have discovered a hoard of coins and don’t want to spend hours researching each individual weight and edge profile.

Understanding the Grade and Value of 2017-S Proofs

When professional coin graders like PCGS or NGC look at a 2017-S George Rogers Clark quarter, they look for “Deep Cameo” (DCAM) or “Ultra Cameo” (UCAM) designations. A perfect grade is a PF70 (Proof 70). Very few coins remain in perfect condition, especially if they have been handled outside of their original plastic lens.

If your coin has fingerprints, scratches, or has lost its mirror-like shine, it will likely grade in the PF60 to PF63 range. Even in lower proof grades, these coins still carry a premium over their face value because of their lower mintage numbers compared to the hundreds of millions produced in Philadelphia and Denver.

Grade Designation	Clad Price Range	90% Silver Price Range
PF 63	$3.50 – $4.50	$10.00 – $12.00
PF 67	$7.00 – $10.00	$18.00 – $22.00
PF 69	$12.00 – $15.00	$25.00 – $30.00
PF 70	$18.00 – $25.00	$45.00 – $60.00

Are There George Rogers Clark Quarter Errors?

Error hunting is one of the most exciting parts of coin collecting. While modern minting processes at the San Francisco Mint are very precise—especially for proof coins—errors can still occur. Look for “doubled die” errors, where the lettering or George Rogers Clark’s muskets appear to have a slight shadow or doubling.

Other things to look for include “strike-throughs,” where debris got between the coin die and the blank, leaving a permanent depression. Because proof coins are inspected individually, these errors are extremely rare and can skyrocket the coin’s value. If you suspect you have found an error, compare your coin to thousands of others using the CoinKnow database to see if it matches known varieties.

The most common “mistake” isn’t an error at all, but rather “post-mint damage.” If the coin has been scratched or dinged while in a vending machine, it won’t be worth more than its face value or melt value. Only errors that occurred at the Mint are considered valuable by collectors.

Where to Sell Your 2017-S Quarter

If you discover that you have a high-grade 2017-S Silver George Rogers Clark Quarter, you might be wondering where to sell it. For coins worth less than $20, online marketplaces like eBay are often the best bet. However, keep in mind that shipping and seller fees can eat into your profit.

For high-grade PF70 or certified error coins, you might consider reaching out to a local coin shop or a reputable auction house. Collectors are always looking for “S” mint quarters to complete their America the Beautiful albums, especially the silver proof versions which were produced in smaller quantities.

Before you sell, make sure you have a firm grasp of the coin’s condition. Using digital tools helps you avoid being low-balled by buyers. Knowledge is power in the numismatic world, and knowing the current market trend for Indiana’s national park quarter will ensure you get a fair price for your find.

FAQ

Q: Why is the George Rogers Clark Quarter from San Francisco more valuable than Philadelphia?

A: The San Francisco Mint (“S”) primarily produces proof coins for collectors in limited quantities. The Philadelphia (“P”) and Denver (“D”) mints produce coins for billions of everyday transactions, making them much more common and less valuable in used condition.

Q: How can I tell if my 2017-S Quarter is silver without weighing it?

A: Look at the edge of the coin. A clad quarter will show a visible copper ring (orange/brown color). A 90% silver quarter will have a solid, bright silver edge. Also, the silver version usually sounds like a higher-pitched “ring” when gently tapped, though weighing it is the safest method.

Q: Is a 2017 George Rogers Clark quarter with no mint mark rare?

A: No. A coin with no mint mark was made in Philadelphia (though in 2017, many Philadelphia quarters actually had the ‘P’ mark). These are very common and usually only worth their face value of 25 cents unless they are in perfect, uncirculated condition.

Q: Can I find a 2017-S George Rogers Clark quarter in my pocket change?

A: It is possible, but rare. These are “Non-Intended for Circulation” (NIFC) or proof coins. If you find one, someone likely spent a coin collectors’ set by mistake. These “circulated proofs” are usually worth about $0.50 to $1.00 because they have been damaged by other coins.

Q: What is the highest price ever paid for this quarter?

A: While standard silver proofs sell for $30-$50, perfect PF70 specimens with special labels or error coins can sometimes reach over $100 at specialized auctions, depending on collector demand at the time.
