The 1973-S Washington Quarter is worth anywhere from $1 in typical proof condition to over $500 for high-grade specimens. While most found in change are common, those minted in San Francisco carry a special “S” mark and a mirror-like finish that makes them stand out to collectors.

Condition / Grade	Estimated Value
PR 65 (Standard Proof)	$1.00 – $3.00
PR 69 Deep Cameo	$15.00 – $25.00
PR 70 Deep Cameo (Perfect)	$150.00 – $550.00+

Identifying the 1973-S Washington Quarter

If you have discovered a shiny quarter from 1973 with a small “S” next to George Washington’s ponytail, you have found a San Francisco Mint proof coin. Unlike the quarters found in your pocket change which were minted in Philadelphia or Denver, these were specifically produced for collectors.

The San Francisco Mint struck over 2.7 million of these coins in 1973. If you are unsure if your coin is a genuine proof or just a very shiny business strike, using a top coin identifier app can help you distinguish the strike type instantly.

Most people find these coins in old collections or “Proof Sets” handed down by relatives. However, because they are made of a copper-nickel clad composition rather than silver, many everyday Americans are surprised to learn that their value depends almost entirely on their physical perfection. CoinKnow is an excellent tool for beginners to start documenting these finds and checking for subtle details that boost value.

The Difference Between Proof and Business Strikes

To understand the 1973-S Washington Quarter value, you must first understand what a “Proof” coin is. In 1973, Philadelphia (no mint mark) and Denver (D mint mark) produced quarters for general circulation. These were tossed into bags and hit each other, resulting in scratches and a duller finish.

The San Francisco Mint (“S”) produced Proofs using specially polished planchets (coin blanks) and dies. These coins were struck twice to ensure the sharpest possible detail. Because they were sold in protective plastic sets, they should technically be in perfect condition.

If you find an “S” mint quarter in the wild that looks scratched or circulated, it is likely an “impaired proof.” These are coins that were broken out of their sets and spent at a grocery store. An impaired 1973-S quarter is usually only worth its face value ($0.25) or perhaps a small premium to a curious kid, while detailed 1973-S quarter price data shows that pristine examples command much higher prices.

Mint Mark	Strike type	Mintage Quantity
None (Philly)	Business Strike	346,924,000
D (Denver)	Business Strike	232,977,400
S (San Francisco)	Proof Strike	2,760,339

Grading and the “Cameo” Effect

When searching for the true market value of your 1973-S quarter, professional grading is key. Collectors look for the “Cameo” (CAM) or “Deep Cameo” (DCAM) designation. These terms describe the contrast between the frosted, white-looking portrait of Washington and the mirrored, dark-looking background (the field).

A standard Proof 1973-S might look shiny, but if the frost on the portrait is patchy or missing, its value remains low. However, a Deep Cameo example is highly sought after. According to current 1973 quarter value charts, the difference between a PR 68 and a PR 70 (perfect) can be hundreds of dollars.

Grading can be complicated for a beginner. Using an app like CoinKnow helps you compare your coin against high-resolution images of graded specimens so you can see if yours has that “pop” required for a high-value sale.

Rare Errors and Varieties for the 1973 Quarter

While the 1973-S is primarily a collector’s coin, error hunters still keep an eye out for anomalies. Major errors on 1973 quarters are rare because the quality control at the San Francisco Mint was very high. However, minor errors do exist across all 1973 quarters, including those from Philly and Denver.

Look for “Off-Center” strikes, where the design is pushed to one side, or “Double Dies,” where the lettering or date appears to have a slight shadow or doubling. While a standard 1973-S is common, an “S” mint proof quarter with a significant minting error could be worth thousands.

If you suspect your coin has a strange lump or missing digit, don’t clean it! Cleaning a coin destroys its numismatic value. Instead, use a magnifying glass or a high-zoom macro camera on your phone to inspect the surface. CoinKnow can assist you in documenting these visual quirks before sending them to a professional for authentication.

Error Type	Description	Potential Value
Off-Center Strike	Design not centered on blank	$50 – $200+
Broadstruck	Struck without the collar (flatter)	$15 – $40
Double Die Obverse	Doubling in the date or LIBERTY	Varies by severity

Is It Silver? The Metal Content Question

A very common question among the American public is whether the 1973-S Washington Quarter contains silver. Unfortunately, the answer for the 1973-S is no. The US Mint stopped regular production of silver quarters in 1964.

The 1973 quarter consists of a core of pure copper with an outer layer of 75% copper and 25% nickel. You can easily tell if it’s “clad” by looking at the edge of the coin. If you see a copper-colored orange/brown stripe running around the middle of the edge, it is a standard clad coin.

While some later proof sets (starting in 1992) offered 90% silver versions, the 1973-S only comes in the copper-nickel variety. Therefore, its value is derived entirely from its rarity in high grades rather than its “melt” or metal value.

The Market for 1973 Washington Quarters Today

The market for modern clad quarters like the 1973-S is stable but specialized. Most casual collectors will pay a few dollars for a nice proof to fill a slot in their album. However, the high-end registry set collectors are the ones driving the triple-digit prices for PR 70 Deep Cameo coins.

If you have a 1973-S that looks like it has never been touched by human hands, it might be worth the investment to have it professionally graded by PCGS or NGC. A perfect grade can change a $3 coin into a $500 coin overnight.

For the average person, keeping the 1973-S as a piece of history is often more rewarding than trying to sell it. It represents an era of transition for the US Mint and remains a beautiful example of American coinage design. Just remember to handle it by the edges to avoid leaving fingerprints on the delicate mirror finish!

FAQ

Q: Where is the mint mark on a 1973 quarter?

A: The mint mark is located on the “obverse” (heads) side, to the right of George Washington’s ponytail. You will see an “S” for San Francisco, a “D” for Denver, or no mark at all for Philadelphia.

Q: Is a 1973 quarter worth anything if it doesn’t have an “S” mark?

A: Most 1973 quarters without a mint mark or with a “D” are only worth their face value of 25 cents if they have been used in circulation. Only those in exceptional uncirculated condition or with major errors are worth more.

Q: How can I tell if my 1973-S quarter is “Deep Cameo”?

A: A Deep Cameo 1973-S will have a very thick, white, “frosted” look on Washington’s face and the eagle on the back, while the flat background looks as dark and reflective as a black mirror.

Q: Should I clean my old 1973 quarters to make them worth more?

A: No! Never clean your coins. Cleaning causes microscopic scratches that professional graders can easily detect, which significantly lowers the coin’s value to collectors.
