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. Whether you found one in a jar of change or inherited a collection, these silver coins are always worth significantly more than their 25-cent face value.
Why Your 1958 Washington Quarter Has No Mint Mark
If you are looking at your coin and cannot find a small letter above the “Quarter Dollar” text on the reverse, don’t worry—it isn’t a mistake. In 1958, the Philadelphia Mint produced over 6.3 million quarters, and at that time, Philadelphia did not use a mint mark on this denomination. These coins are often simply called “1958 Plain” quarters by collectors. Because they are 90% silver, they have an intrinsic bullion value that provides a “floor” for their price, regardless of how scratched or dull they look.
If you aren’t sure how to categorize the condition of your find, you can use a free coin identifier app to get an instant analysis. Tools like the CoinHix app are incredibly helpful for everyday Americans who want to skip the guesswork. By simply snapping a photo, you can determine if your coin is a common circulated piece or a rare gem worth a premium.
Current Market Prices for the 1958 Quarter
The value of a 1958 quarter is primarily determined by its “grade,” which refers to how much wear and tear it has endured. Most coins found in circulation today will fall into the “Good” to “About Uncirculated” categories. However, the real excitement begins with “Mint State” (MS) coins, which look brand new and have never been spent in a store.
For those tracking recent sales, the 1958 Washington Quarter MS price trends show that collectors are willing to pay a heavy premium for coins that retain their original luster. While a heavily worn coin might only be worth its silver weight, a coin graded MS67 can fetch hundreds or even thousands at auction.
| Condition / Grade | Estimated Market Value |
|---|---|
| Good to Fine (Circulated) | $5.50 – $8.00 |
| Extremely Fine (XF45) | $9.00 – $12.00 |
| About Uncirculated (AU58) | $15.00 – $20.00 |
| Mint State (MS63) | $25.00 – $35.00 |
| Gem Mint State (MS66) | $80.00 – $150.00 |
| Superb Gem (MS67+) | $500 – $1,200+ |
The Role of Silver Content in 1958 Quarter Value
Every Washington Quarter minted before 1965 is composed of 90% silver and 10% copper. This means that even if your 1958 quarter is in terrible condition, it will never be worth just 25 cents. It contains approximately 0.1808 troy ounces of pure silver. When silver prices rise, the value of your silver quarters naturally follows.
Experienced hobbyists often use the CoinHix app to track the “melt value” of their silver stacks in real-time. Understanding the 1958 Washington Quarter silver melt value and rarity is essential before you decide to sell your coins to a local dealer or pawn shop. Make sure you don’t sell a high-grade specimen for just the price of its metal!
Tips for Identifying Valuable 1958 Error Quarters
While most 1958 quarters are standard strikes, collectors are always on the lookout for errors. For the 1958 Philadelphia issue, keep an eye out for “Double Die” errors, which appear as slight blurring or doubling on the lettering/date. Looking closely at the “In God We Trust” or the date can reveal these hidden treasures.
When you use the CoinHix app, you can zoom in on high-resolution photos to compare your coin’s features with known error varieties. Finding a verified error can turn a $6 silver coin into a piece worth several hundred dollars. Always handle your coins by the edges to avoid getting fingerprints on the surfaces, as skin oils can damage the silver finish over time.
Frequently Asked Questions
Q: How can I tell if my 1958 quarter is from Philadelphia or Denver?
A: Look on the back of the coin, just above the “R” in the word QUARTER. If there is a small “D,” it was made in Denver. If there is no letter at all, it was minted in Philadelphia.
Q: Is a 1958 quarter worth more than a newer quarter?
A: Yes, significantly. Modern quarters (1965 to present) are mostly copper and nickel. The 1958 quarter is 90% silver, making its base value much higher than its face value.
Q: Should I clean my 1958 silver quarter to make it look shiny?
A: No! You should never clean old coins. Collectors prefer the original “patina” or tarnish. Cleaning a coin causes microscopic scratches that can reduce its collector value by 50% or more.
