Identifying Your 1955 Washington Quarter No Mint Mark

If you have a 1955 quarter and cannot find a small letter below the eagle’s wreath on the back, you have a Philadelphia Mint coin. During the 1950s, the Philadelphia Mint did not use “P” mint marks on quarters. Using a top coin identifier and value app is the fastest way to confirm your coin’s origin and current market standing without needing a magnifying glass.

Modern collectors often prioritize these “no mint mark” coins because the 1955 Philadelphia mintage was relatively low compared to other years in the 1950s. Only about 18 million were struck in Philadelphia, while the Denver Mint produced over 31 million that same year.

To ensure you aren’t mistaking a worn mint mark for a “no mint mark” variety, it helps to use the CoinKnow app to zoom in on the specific area on the reverse side. The absence of a letter means your coin was born in the historic Philadelphia Mint, carrying the legacy of America’s first coining facility.

The Silver Content and Melt Value of 1955 Quarters

The most important thing for “everyday hunters” to know is that 1955 quarters are made of 90% silver and 10% copper. Unlike the copper-nickel quarters we use at the grocery store today (which started in 1965), these vintage coins have intrinsic value.

Even if your coin is scratched, bent, or heavily worn, it is still worth its weight in silver. This is often referred to as “melt value.” When silver prices fluctuate, the base price of your 1955 quarter moves with it. Generally, one of these quarters contains about 0.1808 troy ounces of pure silver.

Collectors rarely sell “melt” coins on their own; they are often traded in rolls. However, if your 1955 Washington Quarter is in beautiful condition, its numismatic (collector) value will quickly exceed the silver price. You can track this specific 1955 Washington Quarter price data to see how the market treats silver and condition rarity differently.

Determining the Grade of Your 1955 Quarter

Grading is the process of deciding how much wear a coin has suffered. For the 1955 Washington Quarter value no mint mark, the difference between a “Fine” grade and an “Uncirculated” grade can be dozens of dollars. In Extremely Fine (XF) condition, you can still see most of the hair lines on Washington’s head and the feathers on the eagle.

In Mint State (MS) condition, the coin must have its original “mint luster”—that frosty sheen found on new coins. If the coin looks like it just came from a bank bag and has no scratches from circulating in pockets, it could be a high-value specimen.

Grade Designation	Visual Description	Value Range
Circulated (G to VF)	Heavy wear, flat surfaces	$6.00 – $10.00
About Uncirculated (AU)	Trace wear on hair and chest	$12.00 – $18.00
MS-63	Strong luster, some bag marks	$25.00 – $40.00
MS-66	Near perfect, bright finish	$150.00 – $300.00

If you are unsure of the grade, the CoinKnow app can help you compare your coin against high-resolution photos of certified grades. Check this comprehensive 1955 quarter value guide to learn more about grading nuances.

Key Varieties and Errors to Watch For

While most 1955 quarters are standard strikes, collectors look for specific errors that can skyrocket the price. Doubled Die errors are the most famous, where the coin shows a clear doubling of letters or images. While the 1955 Doubled Die Penny is a legend, quarters from this year are also inspected for “re-punched” details or striking errors.

Another rare find is the “Proof” strike. The Philadelphia Mint produced nearly 379,000 proof sets in 1955. These coins were made for collectors and have a mirror-like finish. If you find a 1955 quarter that looks like a mirror, it might be a proof that someone accidentally spent decades ago.

Using CoinKnow allows you to identify these subtle differences by comparing your coin’s “sheen” and detail sharpness to known proof examples. A high-grade Proof 69 or 70 can be worth significantly more than a standard business strike.

Why the 1955 No Mint Mark is Special

In the world of mid-century coins, 1955 is often called the “Year of the Rarities” because of the low production numbers across several denominations. While the 1955-D (Denver) is more common, the Philadelphia “No Mint Mark” version is a staple for anyone trying to complete a Washington Quarter set.

Because many of these coins were saved in the 1960s when the U.S. switched away from silver, you can still find them in relatively good condition. However, finding “Gem” quality examples (MS-65 and above) is becoming harder as the years go by. These “survivors” represent the peak of 1950s Americana.

Every year, fewer of these silver quarters remain in the “wild.” Most are now in private collections or have been melted down for their silver. Stumbling upon one today is like finding a small piece of history that effectively pays for your lunch—or much more!

Year/Mint	Mintage Quantity	Scarcity Rank (1950s)
1955 (No Mint Mark)	18,180,181	Moderate
1955-D	31,824,000	Common
1955 Proof	378,200	Rare

How to Store and Protect Your Silver Quarters

If you discover a 1955 quarter that looks shiny and new, do not clean it! This is the #1 mistake new coin finders make. Cleaning a coin with chemicals or even a soft cloth can create microscopic scratches that destroy its collector value.

Instead, hold the coin only by the edges. Place it in a PVC-free plastic flip or a cardboard “2×2” holder. This prevents the silver from tarnishing or reacting with the air. A well-preserved coin will maintain its premium over the silver melt price for years to come.

Many people find these coins in “junk silver” bags. If you have several, keep the high-grade ones separate. Even a small jump in a professional grade (like from MS-64 to MS-65) can double the price of the coin.

FAQ

Q: Where is the mint mark on a 1955 quarter?

A: On the Washington Quarter, the mint mark is located on the reverse (back) of the coin, specifically just below the center of the wreath that the eagle is sitting on. If there is no letter there, it was minted in Philadelphia.

Q: Is a 1955 quarter rare?

A: While not “rare” in the sense that thousands still exist, it is a “better date” for the series due to a lower mintage of 18 million compared to other years which saw over 100 million coins produced. Its 90% silver content makes it highly desirable regardless of rarity.

Q: How much silver is in a 1955 Washington Quarter?

A: Each 1955 quarter is composed of 90% silver and 10% copper. It contains approximately 6.25 grams of total weight, with about 5.625 grams of that being pure silver.

Q: Can I find a 1955 quarter in my pocket change today?

A: It is very unlikely but possible. Most silver coins were pulled from circulation in the mid-1960s. However, sometimes old collections are spent by people who don’t know their value, so always keep an eye out for that distinctive silver “ring” sound!
