Identifying the 1973 Washington Quarter No Mint Mark

If you have a 1973 quarter in your hand and you don’t see a small letter next to Washington’s ponytail, you have a coin minted in Philadelphia. During this era, the Philadelphia Mint did not use a “P” mint mark on quarters. This makes the coin look a bit plain compared to those with a “D” (Denver) or “S” (San Francisco), but it is a standard part of American coinage history.

Millions of these coins were released into circulation, which is why most of them are only worth their face value today. However, because these were workhorse coins used for daily transactions, finding one in “Mint State”—meaning it looks like it just came off the press—is actually quite difficult. Most became scratched and dull within months of entering a vending machine or a cash register.

For the everyday collector, the quickest way to tell if your coin is a winner is to use a top coin identifier and value app. By simply snapping a photo, the CoinKnow app can analyze the surface textures and help you determine if your 1973 quarter is worth more than twenty-five cents. Many users are surprised to find that what looks like a normal quarter actually has a high technical grade.

Understanding the Value of Mint State 1973 Quarters

The real money in the 1973 Washington Quarter No Mint Mark category lies in the “Mint State” (MS) grades. In the world of coin collecting, the Sheldon Scale ranges from 1 to 70. A coin that is graded MS67 is considered “Superb Gem Uncirculated,” and for a 1973 quarter, this is a very rare find.

Because the quality control at the Philadelphia Mint in the early 1970s wasn’t always perfect, many coins were struck with “mushy” details or developed “bag marks” from bumping into other coins in large canvas bags. A 1973 quarter that escaped this fate and remained in pristine condition is highly sought after by registry set collectors.

When looking at the 1973 Washington quarter prices by grade, you will notice a massive jump in value between an MS64 and an MS67. An MS64 might sell for ten dollars, but an MS67 can command hundreds of dollars at auction because there are so few of them certified by professional grading services.

Grade	Market Value (P Mint)
MS63	$5.00
MS65	$28.00
MS66	$115.00
MS67	$1,100.00

Modern Errors and Varieties to Watch For

While most 1973 quarters are standard issues, error hunters are always on the lookout for mistakes made during the manufacturing process. These errors can turn a common twenty-five-cent piece into a valuable specimen. Common errors for this year include “off-center” strikes, where the design is pushed to one side, or “double dies,” where the image appears blurry or doubled.

One interesting variety to look for is the “Clad Layer” error. Since these coins are made of a copper core sandwiched between layers of nickel and copper, sometimes one of the outer layers fails to adhere. This results in a coin that is copper-colored on one side. These errors are rare and immediately increase the 1973 Washington Quarter value.

To help identify these subtle nuances, the CoinKnow app offers a comprehensive database of known errors. Instead of squinting through a magnifying glass, you can use high-resolution digital imaging to spot the signs of a rare error. According to the latest 1973 quarter value and error list, some major errors have sold for well over $200 in recent years.

Silver vs. Clad: Is Your 1973 Quarter Silver?

A common question among new collectors is whether their 1973 quarter contains any silver. The short answer is no—standard 1973 quarters were minted using a copper-nickel clad composition. The U.S. Mint stopped making quarters out of 90% silver in 1964. Unless you have an extremely rare transitional error (which is practically unheard of for this specific year), your 1973 quarter is not silver.

If you want to be 100% sure, you can look at the edge of the coin. A clad coin will show a distinct orange-colored band of copper. A silver coin would have a solid silver-colored edge. Additionally, a clad quarter weighs approximately 5.67 grams, while a 90% silver quarter weighs 6.25 grams.

Even without silver content, the 1973 Philadelphia quarter holds value for collectors who are trying to complete “year sets.” Because it was the era before the Bicentennial (1776-1976) quarters, the 1973 issue represents the final “normal” design year before the massive production of the drummer boy quarters.

Feature	Specification
Composition	75% Copper, 25% Nickel (Clad)
Weight	5.67 grams
Diameter	24.3 mm
Mint Location	Philadelphia (No Mint Mark)

Tips for Preserving and Grading Your Coins

If you believe you have found a high-value 1973 quarter, how you handle it matters. Never clean your coins. Many beginners think that a shiny, scrubbed coin is worth more, but in reality, cleaning a coin removes the original “luster” and creates microscopic scratches that destroy its value. Coin collectors and professional graders prefer natural “patina” or even a bit of grime over a scrubbed coin.

To protect your potential treasure, place the coin in a PVC-free flip or a cardboard “2×2” holder. This prevents oil from your skin from tarnishing the metal. Once protected, you can use the CoinKnow app to get a preliminary assessment of the grade. If the app suggests a grade of MS66 or higher, it might be worth sending the coin to a service like PCGS or NGC for official certification.

Professional grading can cost between $20 and $50 per coin, so it is only worth it if the market value of the coin justifies the expense. For a 1973 Washington Quarter with no mint mark, only the absolute best examples are worth the grading fee. However, finding that one “diamond in the rough” can yield a significant profit if you decide to sell it at a specialized coin auction.

Step	Action to Take
1. Inspection	Check for mint mark and surface scratches.
2. Identification	Use a coin app to find varieties or errors.
3. Storage	Place in a protective holder immediately.
4. Certification	Send to PCGS/NGC if value exceeds $100.

FAQ

Q: Why does my 1973 quarter have no mint mark?

A: This means the coin was minted at the Philadelphia Mint. Until 1980, quarters minted in Philadelphia did not feature a mint mark. It is a standard feature for that year and does not automatically make the coin rare.

Q: Is there a 1973 silver quarter?

A: No, the U.S. Mint did not produce silver quarters for general circulation in 1973. All 1973 quarters found in change are made of a copper-nickel clad composition. Silver quarters only existed before 1965 or in special modern proof sets.

Q: How much is a 1973 quarter worth if it’s dirty?

A: If it has been circulated (spent in stores), it is generally worth the face value of 25 cents. However, if the dirt is covering a high-grade surface or an error, it could still be worth more to a specialist. Do not clean it!

Q: What is the highest price ever paid for a 1973 Philadelphia quarter?

A: The record price for a 1973 Washington Quarter No Mint Mark is over $1,400 for a specimen graded MS67+. In these elite grades, the population of surviving coins is extremely low, driving up prices for competitive collectors.

Q: Can I use an app to value my 1973 quarter?

A: Yes, tools like the CoinKnow app are excellent for identifying the coin and getting a real-time estimate of its market value based on current auction data and surface condition.
