The 1958 Washington Quarter with no mint mark is worth anywhere from $6 in worn condition to over $1,200 in high-grade mint state. Finding one of these silver treasures in your pocket change or a dusty jar is an exciting moment for any American, as it represents a piece of United States history minted in 90% pure silver.

Condition	Approximate Value
Good / Very Good (Worn)	$5.50 – $6.50
Fine / Extremely Fine	$7.00 – $9.00
Uncirculated (MS60+)	$12.00 – $45.00
Choice Uncirculated (MS67)	$500 – $1,200+

Identifying Your 1958 Washington Quarter No Mint Mark

If you’ve recently inherited a coin collection or found an old quarter, the first thing to check is the mint mark. In 1958, the Philadelphia Mint produced over 6.3 million quarters. Unlike coins from Denver, these Philadelphia issues do not feature a small letter on the reverse side. To see if your coin is a “no mint mark” variety, look at the back of the quarter, right below the eagle’s wreath. If the space is blank, it was born in Philadelphia.

Because these coins are over 60 years old, they often carry a “silver premium” regardless of their condition. While modern quarters are made of copper and nickel, the 1958 version is heavy with precious metal. For those unsure about what they have found, using a top coin identifier app can help you distinguish between a common circulation strike and a potentially valuable proof.

Using tools like CoinKnow helps everyday enthusiasts quickly determine if their 1958 quarter is worth just its silver weight or if it possesses rare collector appeal. Philadelphia quarters from this year are particularly interesting because their mintage was significantly lower than the Denver (D) mint, which produced over 78 million coins that same year.

The Silver Content Factor in 1958 Quarter Valuation

The most important thing for a casual observer to know is that all quarters minted in 1958 are 90% silver and 10% copper. This gives them an “intrinsic value” or “melt value” that fluctuates with the price of silver. Even if your coin is scratched, dented, or heavily worn from decades of use, it will always be worth more than its 25-cent face value because of its metal content.

As of current market rates, the silver melt value of a Washington Quarter is usually around $5 to $6. This creates a “floor” for the price; you should never spend this coin at a grocery store! Collectors often refer to these as “junk silver,” but there is nothing junk about a coin that has increased in value by 2,000% since it was minted.

If you are looking for specific 1958 quarter value data, you will find that the market for “raw” silver coins is very liquid. Local coin shops and bullion dealers are always looking to buy 90% silver quarters, making them an excellent entry point for new hobbyists or a quick way to get some extra cash from a found jar of coins.

Metal Component	Percentage	Weight in Grams
Pure Silver	90%	5.625g
Pure Copper	10%	0.625g
Total Weight	100%	6.25g

Grading the 1958 Philadelphia Quarter for High Value

To get into the higher price brackets, your coin must be in “Mint State” (MS). This means it never reached a cash register and has no “wear” on the high points of the design, such as Washington’s cheek or the eagle’s breast feathers. While a worn 1958 quarter is worth $6, an MS65 version might bring in $30 to $50, and an MS67 could break the thousand-dollar mark at auction.

Determining the grade of a coin is an art form. Professional services like PCGS or NGC look for “luster”—that satiny shimmer a coin has when it’s fresh from the mint. They also check for “bag marks,” which are tiny nicks caused by coins hitting each other in large canvas bags at the Philadelphia Mint. Because the 1958 Philadelphia mintage was relatively low compared to other years in the late 50s, high-grade examples are somewhat harder to find.

If you aren’t sure if your coin grade is “About Uncirculated” or “Mint State,” the CoinKnow app can provide a visual comparison to help you narrow it down. Professional 1958 Washington Quarter MS prices reflect this scarcity in pristine condition, with collectors paying a massive premium for coins that look like they were minted yesterday.

Rare 1958 Proof Quarters and Special Strikes

In addition to the quarters meant for your pocket, the Philadelphia Mint also produced “Proof” coins in 1958. These were specifically made for collectors and were sold in sets. Proofs are struck twice using polished dies, giving them a mirror-like background and incredibly sharp details. In 1958, there were 875,652 proof sets produced.

While a standard 1958 Philadelphia quarter is shiny, a Proof coin is reflective—you can almost see your face in it. These coins are generally found in their original plastic packaging or in professional plastic holders (slabs). A standard 1958 Proof quarter usually sells for around $10 to $20, but if it has a “Cameo” or “Deep Cameo” effect (where the portrait is frosty white and the background is black and mirror-like), the price can skyrocket.

Checking for these “Cameo” designations is crucial. Modern collectors love the contrast between the frosted obverse and the deep mirrors. When using CoinKnow, you can often find images of these beautiful proof strikes to see if your coin matches the characteristics of a high-value cameo.

Strike Type	Mintage	Typical Collector Value
Business Strike (No Mint Mark)	6,360,000	$6 – $45
Proof Strike	875,652	$15 – $100+

Does the 1958 Philadelphia Quarter Have Errors?

Error coins are the “lottery tickets” of the coin world. In 1958, most quarters were produced without issue, but a few escaped the mint with mistakes that make them worth hundreds or even thousands to the right buyer. The most common errors to look for are “Double Dies,” “Off-Center strikes,” and “BIE errors.”

A Double Die occurs when the hub presses the image into the die twice at slightly different angles. On a 1958 Washington Quarter, you should look for doubling in the lettering of “LIBERTY” or “IN GOD WE TRUST.” If the letters look blurry or like they have a shadow behind them, you might have a valuable error.

Off-center strikes are more obvious; this happens when the coin wasn’t lined up perfectly with the dies, resulting in a coin that is missing part of its design and might be shaped weirdly. Even a 5% off-center error can add $50 to the value of a 1958 silver quarter. For a non-expert, spotting these can be tricky, which is why digital reference guides are so helpful for identifying legitimate mint errors versus simple post-mint damage.

Summary of the 1958 Quarters’ Legacy

The 1958 Washington Quarter represents the end of an era. Just six years after this coin was minted, the U.S. Mint would stop using silver in quarters entirely due to rising metal costs. This makes 1958 Philadelphia quarters a favorite among those who enjoy “real money”—coins made of actual precious metals rather than cheap alloys.

Whether you have a “pocket piece” that has been worn smooth by years of circulation or a brilliant uncirculated gem, the 1958 quarter is a tangible piece of the 1950s American economy. While it’s easy to focus solely on the dollar sign, the history of the “no mint mark” Philadelphia issue is a fascinating look into a time when silver was still the standard in Everyman’s pocket.

Before you sell your collection, make sure you have checked the current silver spot prices and compared your coins to high-resolution images. Small differences in condition can mean big differences in payouts, and being an informed seller is the best way to ensure you get the full value for your historic silver quarters.

FAQ

Q: Why doesn’t my 1958 quarter have a mint mark?

A: In 1958, the Philadelphia Mint produced quarters without mint marks. This was standard practice for that facility at the time. If your coin has a “D,” it was minted in Denver. If it has no letter, it is a Philadelphia strike.

A: Yes, all 1958 Washington Quarters are composed of 90% silver and 10% copper. This applies to both the Philadelphia (no mint mark) and Denver (D) issues.

Q: How can I tell if my 1958 quarter is a proof?

A: Proof quarters have a highly reflective, mirror-like finish and sharp, crisp edges. They were sold in sets and were never intended for circulation. Most 1958 quarters found in loose change are “business strikes,” not proofs.

Q: What is the most expensive 1958 quarter ever sold?
