1973-S Washington Quarter Value: Price Guide for Collectors

The 1973-S Washington Quarter is worth anywhere from $1 in typical proof condition to over $500 for elite specimens with perfect grades and heavy frosting. While these coins were not released into general circulation, many Americans find them in inherited collections or old proof sets and wonder about their current market standing.

Condition / Grade	Estimated Market Value
PR 65 (Common Proof)	$1.00 – $3.00
PR 67 Deep Cameo	$5.00 – $12.00
PR 69 Deep Cameo	$25.00 – $45.00
PR 70 Deep Cameo (Perfect)	$250.00 – $600.00+

History and Production of the 1973-S Quarter

By 1973, the United States Mint had fully stabilized its copper-nickel clad production after transitioning away from silver in 1965. The San Francisco Mint, denoted by the “S” mint mark, was exclusively tasked with producing “Proof” coinage for collectors. Unlike the Philadelphia and Denver quarters meant for your pocket change, the 1973-S was struck with specially polished dies and planchets to create a mirror-like finish.

If you have discovered one of these coins in a box of old belongings, you are likely looking at a piece from a 1973 United States Proof Set. If you are unsure whether your coin is a standard strike or a special proof, using a top coin identifier and value app can help you distinguish between production types instantly.

During this era, the San Francisco Mint struck over 2.7 million of these proof quarters. While that sounds like a large number, the survival rate of coins in “perfect” condition is surprisingly low. Over the decades, many proof sets were broken open, and the coins were either handled with bare hands—leaving damaging oils—or spent by accident, which wears down the delicate mirrored finish.

How to Identify a 1973-S Washington Quarter

Identifying the 1973-S Washington Quarter is relatively straightforward for the average person. Look at the obverse (the “heads” side) depicting George Washington. To the right of his ponytail, you will see the small “S” mint mark. If there is no mark, it was made in Philadelphia; if there is a “D,” it was made in Denver.

However, the “S” isn’t the only thing that makes this coin special. Because it is a proof coin, it features a high-relief strike and a reflective background. Collectors specifically look for the “Cameo” (CAM) or “Deep Cameo” (DCAM) effect. This is where the devices (Washington’s head and the lettering) appear frosted and white, while the field remains like a dark mirror.

If your coin looks dull or has scratches, it has likely lost its “Proof” status in the eyes of professional graders. To get a better sense of how your coin’s appearance affects its price, you can check the 1973-S quarter value breakdown to see where your specific coin falls on the quality spectrum. The CoinKnow app is also a fantastic tool for comparing your coin’s luster against high-resolution images of certified samples.

Determining the Value of a 1973-S Quarter

When evaluating the 1973-S Washington Quarter, the price is almost entirely dependent on the numerical grade. In the world of numismatics, coins are graded on a scale from 1 to 70. Since these are proof coins, they usually start at PR 60. A standard PR 63 or PR 65 coin is very common and typically sells for just a couple of dollars.

The real money lies in the PR 69 and PR 70 Deep Cameo designations. A PR 70 Deep Cameo is a “perfect” coin under 5x magnification, showing no spots, hairs, or scratches. These are exceptionally rare because the minting process in 1973 wasn’t as refined as it is today. You can view the latest 1973 quarter price trends to see how the market fluctuates for these top-tier grades.

For the average person, it is important to manage expectations. If the quarter has been rolling around in a drawer or a jar of change, it is almost certainly not a PR 70. However, if it is still sealed in its original purple-themed 1973 Proof Set plastic lens, it might be worth having a professional look at it. Using CoinKnow can help you determine if the coin has “Deep Cameo” potential before you spend money on professional grading fees.

Grading and Condition Impacts

Grading is subjective but follows strict criteria set by organizations like PCGS or NGC. For the 1973-S, the most important factor is the preservation of the “frosted” details. As dies were used repeatedly at the mint, the frosting would wear thin. Early strikes from a fresh die produced “Deep Cameo” coins, while later strikes produced “Cameo” or “Brilliant” proofs.

A “Brilliant” proof (one without any contrast between the frosting and the mirror) is the least desirable among collectors. Even in a high grade like PR 68, a Brilliant proof might only fetch $5. Meanwhile, a Deep Cameo in the same grade could double or triple that price. The jump to PR 69 and PR 70 is where the value truly explodes.

Grade Designation	Visual Appearance	Approx. Value
Standard Proof	Uniformly shiny, no contrast	$1 – $5
Cameo (CAM)	Light frost on Washington’s face	$10 – $25
Deep Cameo (DCAM)	Heavy, snow-white frost; deep mirrors	$40 – $500+

Are There Any Rare 1973-S Errors?

While most 1973-S quarters are standard proofs, collectors are always on the hunt for errors. Error coins can significantly increase the value of a 1973-S Washington Quarter. One of the most common types of errors found in proof sets of this era are “Off-Center strikes” or “Double Dies,” though these are extremely rare for the 1973-S specifically.

Another thing to look for is proof coins struck on the wrong planchet. For example, if a quarter planchet intended for circulation (Philadelphia or Denver) was accidentally fed into the proof press, it might lack the high-quality polish but still bear the “S” mark. Such “Proof-Like” Business strikes are highly coveted by specialists.

If you think you see something odd—like blurry lettering or a weird texture—don’t clean the coin! Cleaning a coin destroys its numismatic value instantly. Instead, use a magnifying glass or the CoinKnow app’s high-zoom feature to inspect the details. Many “errors” found by beginners are actually just post-mint damage caused by the coin hitting other objects.

Where to Sell Your 1973-S Quarter

If you have confirmed that your 1973-S Quarter is in elite condition or features a “Deep Cameo” finish, you have several options for selling. For common proofs, local coin shops or online marketplaces like eBay are the most efficient. You likely won’t get more than a few dollars, but it’s a quick way to turn metal into cash.

For high-grade coins (PR 69 or PR 70), you should consider professional auction houses like Heritage Auctions or GreatCollections. These venues attract serious collectors willing to pay a premium for “Registry Set” coins. Keep in mind that getting a coin professionally graded costs money (often $30-$50 per coin), so only submit coins that you are confident will achieve a high grade.

Before selling, always research the most recent realized prices. Coin values change based on market demand and the number of newly discovered high-grade specimens. Staying informed through hobbyist forums and value apps ensures you don’t get underpaid for a rare find in your collection.

FAQ

Q: Is the 1973-S Quarter made of silver?

A: No. The last silver quarters intended for regular proof sets were minted in 1964. The 1973-S Washington Quarter is a copper-nickel clad coin. It has a visible copper stripe on the edge. If you find a silver-edged 1973 quarter, it is likely a plated “novelty” coin, as the Mint did not produce silver quarters that year.

Q: Can I find a 1973-S Quarter in my pocket change?

A: It is very rare but possible. This happens when someone breaks open a proof set and spends the coins. If you find one in circulation, it will usually be worn and scratched, meaning its value will be limited to its face value of 25 cents or perhaps a small premium to a curious collector.

Q: What does the “S” stand for?

A: The “S” stands for the San Francisco Mint. During 1973, the San Francisco Mint was responsible for producing all “Proof” coinage for the United States, which were sold directly to collectors in sets.

Q: Why is my 1973-S Quarter worth only 25 cents?

A: If the coin has heavy scratches, fingerprints, or wear from being used as money, it loses its “Proof” appeal. Collectors pay for beauty and perfection. A “damaged” proof coin is generally worth only its face value unless it has a major mint error.
