The 2015-S Bombay Hook Quarter is worth anywhere from $0.25 in circulated condition to over $500 for high-grade silver specimens. Whether you found one in your pocket change or inherited a mint set, understanding the specific “S” mint mark variations is the key to discovering if you have a common coin or a rare treasure.

Version Type	Average Value	Mint State (MS/PF 67+)
2015-S Copper-Nickel Business Strike	$0.50 – $2.00	$15 – $35
2015-S Clad Proof	$3.00 – $5.00	$10 – $20
2015-S Silver Proof	$10.00 – $15.00	$40 – $500+

History and Design of the Bombay Hook Quarter

The 2015 Bombay Hook National Wildlife Refuge quarter is the 29th release in the “America the Beautiful” (ATB) series. This massive program, which began in 2010, commemorates national parks and historic sites across the United States. If you are unsure exactly which version you have, using a top coin identifier app can help you distinguish between the standard circulation strikes and the rarer collector editions.

The reverse design of this coin is particularly striking. It features a great egret in the foreground and a black-crowned night heron in the background, standing among the marsh grass of the Delaware refuge. The Bombay Hook National Wildlife Refuge was established in 1937 as a breeding ground for migratory birds. Because of the intricate details in the heron’s feathers and the marsh grass, this coin is a favorite among nature lovers and hobbyists alike.

When examining your coin, you will see “BOMBAY HOOK” across the top and “DELAWARE” at the bottom left. The date 2015 is centered at the bottom. While hundreds of millions of these quarters were minted in Philadelphia (P) and Denver (D) for general commerce, the “S” mint mark coins from San Francisco were produced in significantly lower numbers, making them more attractive to collectors using CoinKnow.

Understanding the Three 2015-S Quarter Variations

Not all “S” quarters are created equal. In 2015, the San Francisco Mint produced three distinct types of Bombay Hook quarters. First is the “Business Strike” S-mint. These were sold in special bags and rolls by the U.S. Mint and were not released into general circulation. If you find one in your change, someone likely broke open a collector set to spend it.

Second is the Clad Proof. These are specially polished coins with mirror-like backgrounds and frosted designs. They are made of the same copper-nickel material as your standard pocket change but look significantly more “shiny.” You can find 2015 quarter value updates that track these proof sets as they age in the market.

Finally, there is the Silver Proof. This is the most valuable version for the average person. It is composed of 90% silver and 10% copper. These coins have a distinct bright white luster and lack the copper “sandwich” edge visible on standard quarters. When a Silver Proof reaches a perfect grade, its value can skyrocket into the hundreds of dollars.

Mint Mark & Type	Mintage Volume	Rarity Level
2015-S Business Strike (NIFC)	Approx. 1,000,000	Uncommon
2015-S Clad Proof	600,000+	Scarce
2015-S Silver Proof	300,000+	Rare

Evaluating the 2015-S Bombay Hook Quarter Condition

The value of any coin is dictated by its “grade,” or its state of preservation. For the 2015-S Bombay Hook Quarter, collectors use the Sheldon Scale, which ranges from 1 to 70. A coin that has been touched by hands, scratched, or dropped is “Circulated.” Even an “S” mint coin loses most of its premium if it shows significant wear. Using CoinKnow allows you to compare your coin’s condition to high-resolution photos of graded examples.

Modern quarters are usually graded as “Mint State” (MS) or “Proof” (PF/PR). An MS65 coin is considered a high-quality “Gem,” while an MS68 or MS69 is almost perfect. Because 2015 is relatively recent, the market is flooded with high-grade coins. To truly make money, your coin needs to be a “Top Pop” (top population), meaning it is among the highest graded by professional services like PCGS or NGC.

When looking at America the Beautiful quarter price records, you will notice that even slight scratches across the heron’s body or the egret’s wing can drop the price from $50 down to $2. If you have a Silver Proof, ensure you handle it only by the edges to prevent skin oils from damaging the precious metal surface.

Are There Any Rare Bombay Hook Quarter Errors?

While the 2015-S versions are generally high-quality because they were made for collectors, errors can still occur. Error hunting is one of the most exciting parts of coin collecting for everyday Americans. One thing to look for on Bombay Hook quarters is “Die Cracks.” These appear as raised lines of metal where the coin die began to break during the striking process.

Another common error to look for is the “Doubled Die.” This happens when the hub strikes the die twice at slightly different angles, resulting in doubling on the lettering or the birds’ features. While a major doubled die hasn’t been widely publicized for the 2015-S Bombay Hook, minor doubling can still command a premium from specialized collectors.

If you suspect you have an error, don’t clean the coin! Cleaning a coin is the fastest way to destroy its numismatic value. Instead, use a magnifying glass or a digital microscope to zoom in on the “S” mint mark and the lettering. If the doubling is clear and distinct, your $0.25 coin could suddenly be worth $20, $50, or even more.

How to Identify a Silver vs. Clad Quarter

Many people find an “S” mint quarter and immediately assume it is silver. However, most San Francisco quarters from 2015 are actually clad (copper-nickel). Identifying the difference is crucial for determining the 2015-S Bombay Hook Quarter value. The easiest method is the “Edge Test.” Look at the side of the coin; if you see a brownish-orange stripe, it is a clad coin. If the edge is solid silver-white, it’s likely a 90% silver proof.

Another method is the “Weight Test.” A standard clad quarter weighs approximately 5.67 grams. In contrast, a 90% silver quarter is heavier, weighing roughly 6.25 grams. Most jewelry scales or small kitchen scales can help you verify this at home. If you want a digital solution, CoinKnow provides detailed specs to help you cross-reference your findings.

The silver content alone makes the 2015-S Silver Proof worth significantly more than face value, regardless of the collector market. As the price of silver fluctuates, the “melt value” of these quarters provides a solid floor for their price. Typically, the silver value stays around $4 to $6, but the collector value for a pristine 2015-S Silver Bombay Hook quarter is usually higher.

Material	Weight	Edge Appearance
Clad (Copper-Nickel)	5.67g	Visible copper layer
90% Silver	6.25g	Solid silver/white

Where to Sell Your 2015-S Bombay Hook Quarter

If you’ve determined that your quarter is a high-grade silver proof or a rare “S” business strike, your next step is finding a buyer. For common circulated “S” clad quarters, you might find a buyer on eBay for $1 or $2, but after shipping and fees, it’s often not worth the effort. These are best kept in a folder as part of a complete ATB set.

For high-value silver versions or coins that look absolutely perfect (MS68 or higher), consider professional grading. Once a coin is “slabbed” by PCGS or NGC, it becomes much easier to sell to serious collectors. Online marketplaces and local coin shops are the most common outlets. Be warned that coin shops usually pay “wholesale” prices, while selling directly to other collectors online can net you “retail” prices.

Always keep an eye on current market trends. The America the Beautiful series remains popular, and as the program ended in 2021, many collectors are now looking back to fill the holes in their collections. This renewed interest can drive up the price of earlier issues like the 2015 Bombay Hook.

FAQ

Q: Why is there an “S” on my 2015 Bombay Hook quarter?

A: The “S” stands for the San Francisco Mint. Unlike Philadelphia (P) or Denver (D) coins, “S” mint quarters were not intended for general circulation. They were produced specifically for collectors in proof sets or limited-edition rolls.

Q: Is the 2015-S Bombay Hook Quarter made of real silver?

A: Some are, and some are not. The San Francisco Mint produced both “Clad” (copper-nickel) and “90% Silver” versions of the Bombay Hook quarter. You can check the edge or weigh the coin to determine which one you have.

Q: How much is a circulating 2015-P or 2015-D Bombay Hook quarter worth?

A: Generally, if it has a P or D mint mark and you found it in your change, it is only worth its face value of $25 cents. However, if it is in “uncirculated” condition (still looks brand new/shiny), it might be worth $0.50 to $1.00 to a collector.

Q: What is the most expensive 2015-S Bombay Hook quarter ever sold?

A: High-grade Silver Proofs (PR70 Deep Cameo) typically represent the highest sales, often reaching between $100 and $500 depending on the auction and current silver prices. Standard clad versions rarely exceed $30 unless they are in perfect condition.
