The 2019 S American Memorial Quarter is worth anywhere from $1 in circulated condition to over $500 for high-grade silver proofs. If you just pulled a 2019 quarter out of your pocket or a jar of loose change, finding that small “S” mint mark could mean you have something more valuable than a standard twenty-five cent piece.
Identifying Your 2019 San Francisco Mint Quarter
When people talk about the “American Memorial Quarter,” they are referring to the America the Beautiful series, which honored national parks and historic sites. In 2019, the U.S. Mint released five different designs: Lowell, American Memorial (Northern Mariana Islands), War in the Pacific, San Antonio Missions, and Frank Church River of No Return.
The “S” mint mark signifies that the coin was struck at the San Francisco Mint. Unlike the standard “P” or “D” quarters you see every day, S-mint quarters were generally not intended for general circulation. Many were sold in special sets or as limited rolls to collectors. If you are unsure exactly which design you have, using a top coin identifier app can quickly tell you the specific park it represents.
To find the mint mark, look at the front (obverse) of the coin with George Washington. To the right of his ponytail, you will see a tiny letter. If it is an “S,” you have a coin that was produced in much lower quantities than the billions of common quarters found in the wild. While most S-mint coins are Proofs with a mirror-like finish, some are “NIFC” (Not Intended For Circulation) business strikes, which are also highly sought after by enthusiasts using the CoinHix app to track their collections.
Distinguishing Between Clad and Silver Proof Versions
The value of your 2019-S quarter depends heavily on its metal composition. In 2019, the San Francisco Mint produced two distinct versions for collectors: Copper-Nickel Clad and 99.9% Fine Silver. Identifying which one you have is the first step in determining the current market price for 2019 American Memorial quarters found in collections.
Clad proof quarters have a copper core, which is visible as a reddish-brown stripe along the edge of the coin. These usually sell for a few dollars. However, the Silver Proof versions do not have a copper stripe; they are bright white all the way around the edge. Because these contain actual precious metal, they have a “melt value” that fluctuates with the price of silver, though their collector value usually exceeds the silver price alone.
Keep in mind that 2019 was a special year because it was the first year the Mint switched from 90% silver to 99.9% fine silver for proof sets. This makes the 2019-S silver quarters particularly desirable for those building a complete set of “silver state quarters.” Many people find that 2019-S coins in pristine condition are the crown jewels of their “pocket change” hunts, and they often use CoinHix to catalog these finds.
Value Breakdown and Price Guide
Prices for these quarters can vary wildly based on the specific design and the condition of the coin. Professionals use a grading scale from 1 to 70. Most coins found in circulation will be on the lower end, while those kept in original mint packaging will be MS (Mint State) or PR (Proof).
The American Memorial Park design, specifically, is a favorite because of its intricate depiction of the memorial honors the people who died during the Marianas Campaign of WWII. If you are monitoring the value of 2019 series quarters by condition, you will notice that high-grade specimens (PR69 or PR70) can fetch a significant premium at auction.
| Coin Type / Condition | Estimated Market Value |
|---|---|
| 2019-S Clad (Circulated) | $0.50 – $1.50 |
| 2019-S Clad Proof (PR65-69) | $4.00 – $12.00 |
| 2019-S Silver Proof (PR69) | $15.00 – $25.00 |
| 2019-S Silver Proof (PR70 Deep Cameo) | $50.00 – $150.00+ |
| 2019-S Business Strike (Uncirculated) | $2.00 – $8.00 |
Why the S Mint Mark Matters So Much
To the average person, a quarter is just a quarter. However, the rarity of the San Francisco strikes elevates them above the common “P” (Philadelphia) and “D” (Denver) coins. While billions of quarters are minted for commerce every year, S-mint coins are produced in the hundreds of thousands or low millions. This scarcity is what drives the 2019-S American Memorial Quarter value upward.
Collectors often look for “Deep Cameo” effects on S-mint proofs. A Deep Cameo coin has a heavy frosted appearance on the design elements (like the memorial or Washington’s head) and a highly polished, mirror-like background. These are the “perfectionist” versions of the coin and are the most valuable.
If you happen to find an S-mint quarter that doesn’t look shiny and mirror-like, you might have found an “Uncirculated Business Strike” from a special mint roll set. These are extremely rare to find in circulation because they were sold directly to collectors. Finding one in your change is like winning a small lottery. You can check the rarity levels and current bids on the CoinHix app to see if you should get your find officially graded.
Factors That Increase or Decrease Coin Value
Beyond the mint mark, the physical condition of the coin is the most important factor. Scratches, wear on the high points (like the curls in Washington’s hair), and dullness significantly lower the value. Even a silver quarter, if it is “beat up,” might only be worth its weight in silver rather than its collectible value.
Tarnish or “toning” can also impact price. Some collectors love beautiful rainbow toning and will pay a premium for it. Others prefer a blast-white, clean look. One thing you should never do is clean your coins. Cleaning a 2019-S quarter with polish or soap can create micro-scratches that ruin its numismatic value instantly.
Lastly, look for errors. While rare in 2019-S quarters, things like “doubled dies” or “clipped planchets” can turn a $5 coin into a $500 coin. If something looks “wrong” or “doubled” on the letters of the coin, it is worth consulting a professional or using an app to verify the error status before spending it.
Frequently Asked Questions
Q: How can I tell if my 2019-S quarter is real silver?
A: Look at the edge of the coin. If you see a solid silver-colored edge without a copper stripe, it is likely the 99.9% fine silver version. You can also use a precise scale; silver quarters weigh 6.25 grams, while clad quarters weigh 5.67 grams.
Q: Are the 2019-W quarters more valuable than the 2019-S quarters?
A: Generally, yes. In 2019, the West Point Mint (“W” mint mark) released 2 million of each design directly into circulation as a “Great American Coin Hunt” promotion. These are very rare and highly valuable in any condition. However, a high-grade Silver Proof 2019-S can still compete with a 2019-W in terms of value.
Q: Should I spend a 2019-S quarter if I find one in my change?
A: No, you should keep it! Even the most common clad 2019-S quarter is worth more than its 25-cent face value to a collector. It is best to put it in a protective sleeve or flip to preserve its condition.
Q: What is the highest price ever paid for a 2019 quarter?
A: Some “W” mint quarters and “S” silver proofs in perfect PR70 condition have sold at major auctions for several hundred dollars, especially if they are part of a renowned set or possess a unique error.
