Identifying Your 2015-S Bombay Hook Silver Quarter
If you just looked through a jar of coins and spotted a 2015 quarter with a “S” mint mark, you might have hit a small jackpot. Most American quarters are “clad,” meaning they contain no precious metals. However, the San Francisco Mint produced a special version of the Bombay Hook National Wildlife Refuge quarter specifically for collectors using 90% silver. This makes the coin look whiter and sound much more melodic when dropped on a table compared to a standard coin.
To be sure what you have, you should use a top coin identifier app to verify the metal composition. If you don’t have a scale or specialized tools, look at the edge of the coin. If you see a solid silver stripe without a copper “sandwich” line in the middle, you likely have the silver version. Utilizing the CoinKnow app can help you scan the coin’s surface to detect the fine details that distinguish a proof strike from a circulation strike.

The Bombay Hook quarter is the 29th release in the America the Beautiful Quarters Program. The design features a great egret in the foreground with a black-crowned night heron in the background, set against a salt marsh. While millions were made for general use in Philadelphia and Denver, the silver “S” specimens were minted in much smaller quantities, directly impacting their scarcity and price today.

Determining the Mint State and Proof Value
Value in the coin world is almost entirely dependent on “grade,” which is a professional assessment of the coin’s wear and tear. A 2015-S Bombay Hook Silver Quarter that has been handled and spent is worth significantly less than one that has been kept in its original protective packaging. The silver content itself provides a “price floor,” meaning the coin will always be worth at least its weight in silver bullion.
When checking the current market, it is helpful to look at the detailed price trends for 2015 silver quarters. For those lucky enough to find a specimen that looks perfect—meaning no scratches, high luster, and a mirror-like field—the value can jump into the triple digits. Professional grading services like PCGS or NGC are often used for the highest-quality coins to certify their “PR70” status.

Silver vs. Clad: How to Tell the Difference
For everyday Americans, the most confusing part of the 2015 quarters is that the “S” mint mark was actually used for two different types of collector coins: the Silver Proof and the Copper-Nickel Clad Proof (and even some “S” Uncirculated Clad coins). This leads to a lot of confusion when trying to determine the true value of a 2015 Bombay Hook quarter found in circulation or a collection.
The easiest way to tell is the weight. A standard clad quarter weighs 5.67 grams, while a 90% silver quarter weighs 6.25 grams. If you have a precise kitchen scale, this is a foolproof way to know if you’re holding silver. Furthermore, the CoinKnow app can provide side-by-side visual comparisons so you can see the brilliance of a silver finish. Silver has a much higher reflectivity and a “colder” white tone than the slightly yellowish or grayish tint of nickel.

Market Demand for America the Beautiful Silver Quarters
The America the Beautiful (ATB) series is incredibly popular because it celebrates national parks and wildlife preserves across all 50 states and territories. The 2015-S Bombay Hook Silver Quarter is particularly sought after by bird watchers and nature enthusiasts, not just coin collectors. This “cross-over” appeal often keeps the prices stable even when the price of raw silver fluctuates.
Because these were originally sold in sets (like the 2015 Silver Proof Set), finding an individual one in the wild is rare. Most often, these coins enter circulation when a collection is stolen or accidentally spent by someone who doesn’t realize the “S” mark indicates a premium item. If you find one in your change, it is considered a “wild find” and should be put in a protective sleeve immediately to prevent further scratches.

Tips for Selling Your Silver Quarter
If you have realized your coin is a 2015-S silver specimen and you’re ready to sell, don’t just take it to a generic “We Buy Gold” shop. These shops often only pay the “melt value,” which is just the price of the metal. Because the Bombay Hook design is part of a collectible series, it often carries a numismatic premium above the silver price. Using CoinKnow can help you track recent auction results so you know exactly what collectors are currently paying.
Online marketplaces like eBay are great for selling individual quarters, but be sure to take high-quality, clear photos of both the front and back. Mention the “S” mint mark and the silver content clearly in the title. If the coin is in a plastic slab from a grading company, it will sell faster and for a more predictable price. Always check recent “Sold” listings rather than “Active” listings to see the actual cash value people are shelling out.
Frequently Asked Questions
Q: Is there a 2015-S Bombay Hook quarter that isn’t silver?
A: Yes. The San Francisco Mint also produced “Clad” proof quarters and “Clad” uncirculated quarters with the “S” mint mark. These are made of copper and nickel and are generally worth $1 to $5, significantly less than the 90% silver version.
Q: How can I tell if my 2015 quarter is an error coin?
A: Error coins might have “doubled dies” (where the letters look like they were stamped twice) or “off-center strikes.” While rare for the 2015-S silver series, any unusual bump or missing letter should be examined by an expert or a coin identification app.

Q: Where is the mint mark on the Bombay Hook quarter?
A: The mint mark is located on the “heads” side (obverse). Look to the right of George Washington’s ponytail, just below the “In God We Trust” motto. You are looking for a small letter “S.”
Q: Does the value of the coin change with the price of silver?
A: Yes, partially. Since the 2015-S Bombay Hook Silver Quarter contains actual silver, its “floor price” rises and falls with the global silver market. However, its collector value (numismatic value) usually stays higher than the raw metal price.
