The 1911-S Barber Quarter Dollar is worth anywhere from $45 in worn condition to over $1,200 in uncirculated mint state. Finding one of these silver coins in your change or an old collection is an exciting discovery because the San Francisco mint produced very few of them compared to other years.

History and Rarity of the 1911-S Barber Quarter

The 1911-S Barber Quarter is a fascinatng piece of American numismatic history, featuring a design by Charles E. Barber that graced silver coinage for twenty-four years. By 1911, the San Francisco mint was focused on a variety of denominations, and the production of quarters was significantly lower than the outputs seen in Philadelphia or Denver. This scarcity is exactly why ordinary Americans get so excited when they stumble upon one today. If you are unsure if your coin is the right one, using a top coin identifier app can help you confirm the date and mint mark in seconds.

The 1911-S is often considered a “semi-key” date in the series. While it isn’t quite as rare as the legendary 1896-S or 1901-S, it is far more valuable than a common-date Barber quarter from the late 1890s. Most of these coins saw heavy circulation during the early 20th century, meaning they were passed from hand to hand during the Wilson and Taft administrations. Finding one with original detail remaining is a rare treat for any collector.

To get the most accurate valuation, many hobbyists use the CoinKnow app, which provides real-time market data based on recent auction results. This helps ensure you don’t sell a valuable San Francisco coin for silver scrap prices. Because this coin contains 90% silver, it will always have “melt value,” but its numismatic rarity usually pushes the price much higher than the raw metal cost.

Identifying the S Mint Mark and Coin Details

To determine the 1911-S Barber Quarter Dollar value, you must first verify that it was actually struck in San Francisco. The “S” mint mark is located on the reverse (back) of the coin, specifically just below the eagle’s tail feathers and above the letters “R” and “T” in the word “QUARTER.” If there is no letter there, the coin was minted in Philadelphia and is worth significantly less.

The design itself is iconic. The obverse features Liberty wearing a Phrygian cap and a laurel wreath, while the reverse showcases a heraldic eagle holding an olive branch and arrows. Because these coins are over 110 years old, the details are often worn smooth. However, even a heavily worn 1911-S retains a premium because only 982,000 were ever minted.

Feature	Specification
Composition	90% Silver, 10% Copper
Weight	6.25 Grams
Diameter	24.3 mm
Mintage	982,000

Determining the Grade and Condition

The condition, or “grade,” of your coin is the biggest factor in determining its final price. Collectors use a scale from 1 to 70. For a 1911-S Barber Quarter, the difference between a coin where Liberty’s face is flat and one where you can read the word “LIBERTY” in her headband can be hundreds of dollars. Many people who find these coins use the CoinKnow app to compare their coin’s appearance to high-resolution images of graded samples.

In “Good” condition, the motto “IN GOD WE TRUST” on the front will be nearly gone, and the rim will be worn down into the letters. As you move up to “Fine” or “Very Fine,” you will start to see the leaves in the wreath and the individual feathers on the eagle’s wings. If you happen to find one that looks shiny and new with no scratches, you could be looking at a four-figure payday.

Much like the 1911 Barber dime worth, the quarter from this year is highly sought after when it maintains its original luster. Always handle these coins by the edges to avoid leaving fingerprints, which can corrode the silver over time and lower the grade.

1911-S Barber Quarter Value Chart by Grade

When selling or buying, it is helpful to have a breakdown of what each grade typically sells for in the current market. These prices reflect coins that have been certified by professional grading services like PCGS or NGC. Raw, uncertified coins often sell for slightly less because their grade isn’t “guaranteed” to the buyer.

Grade	Market Value (USD)
G-4 (Good)	$48
F-12 (Fine)	$125
EF-40 (Extremely Fine)	$310
AU-58 (Choice About Uncirculated)	$675
MS-63 (Mint State)	$1,650
MS-65 (Gem Uncirculated)	$4,200+

Why the San Francisco Mint Matters

In 1911, the San Francisco Mint (S) was often producing coins in much smaller quantities than Philadelphia (No Mint Mark) or Denver (D). For the Barber Quarter series, San Francisco is known for producing some of the rarest dates. While the 1911-S is not the rarest of all, its mintage of under 1 million makes it a “low mintage” coin by modern standards. For comparison, modern quarters are often minted in the hundreds of millions.

Collectors who are trying to complete a “date and mint mark” set of Barber Quarters often find the 1911-S to be one of the more difficult holes to fill. This steady demand from collectors keeps the 1911-S Barber Quarter Dollar value stable even when the price of silver fluctuates. It is a true collector’s item rather than just a bullion coin.

The CoinKnow platform can help you track the auction history specifically for “S” mint coins from this era. Because many of these coins were saved in the West, they occasionally turn up in estate sales in California, Oregon, and Washington. If you live in these areas, it’s worth checking through old family jars of silver.

Tips for Selling Your 1911-S Quarter

If you decide to sell your 1911-S Barber Quarter, do not clean it! This is the most important rule in coin collecting. Cleaning a coin with polish or even soap and water creates microscopic scratches that look “unnatural” to professional buyers. A cleaned coin can lose up to 50% of its value immediately. Collectors prefer the “patina” or natural toning that comes with age.

Instead, take clear, high-resolution photos of both sides of the coin. You can use an app to get a preliminary idea of the grade and then visit a local coin shop for a professional opinion. If the app suggests the coin is in “Extremely Fine” or better condition, it might be worth sending it to a grading service like PCGS to maximize your profit.

Selling Channel	Pros/Cons
Local Coin Shop	Fast cash, but usually 60-70% of retail value.
Online Auctions (eBay)	Higher potential price, but fees and shipping risks.
Professional Auction Houses	Best for high-value MS-65+ grades.
