Understanding What is Constitutional Silver?
What is Constitutional Silver? A Guide for Collectors and Investors
If you’ve spent any time in the world of coin collecting or precious metals investing, you’ve probably come across the term “constitutional silver.” But what exactly does it mean? Why is it important for coin collectors, dealers, and investors to understand this category of coins? In this article, we’ll break down the definition, history, and value of constitutional silver, focusing on the most common U.S. coins and how to calculate their worth.
What is Constitutional Silver?
Constitutional silver refers to U.S. coins minted in 1964 or earlier that contain 90% silver and 10% copper. The name comes from the fact that these coins were issued before the government moved away from using silver in everyday circulating money. Collectors and investors sometimes also call it “junk silver,” although that phrase can be misleading. There’s nothing “junk” about the intrinsic value of these coins—the nickname just means they’re valued more for their silver content than for rarity or numismatic appeal.
Why Was Silver Removed from U.S. Coins?
From the late 1700s through 1964, silver was a core part of American coinage. However, by the early 1960s, rising silver prices meant that the metal inside the coins was becoming more valuable than their face value. To prevent hoarding and melting, the U.S. Mint transitioned to copper-nickel clad coinage in 1965. The result is that all circulating dimes, quarters, and half-dollars from 1964 and earlier contain 90% silver.
Common Types of Constitutional Silver Coins
While many denominations fall into the constitutional silver category, investors and collectors often focus on a few key series:
Mercury Dimes (1916–1945)
- Composition: 90% silver, 10% copper
- Silver Content: Each dime contains 0.07234 troy ounces of silver.
- Notes: Known for Adolph A. Weinman’s iconic design, Mercury dimes are both collectible and a staple in bulk silver bags.
Roosevelt Dimes (1946–1964)
- Composition: 90% silver, 10% copper
- Silver Content: Like the Mercury dime, 0.07234 troy ounces of silver.
- Notes: Still widely available and often mixed into 90% silver “junk silver” lots.
Standing Liberty Quarters (1916–1930)
- Composition: 90% silver, 10% copper
- Silver Content: 0.18084 troy ounces of silver per coin.
- Notes: Highly collectible, with artistic appeal and scarcity in high grades.
Washington Quarters (1932–1964)

Walking Liberty Half-Dollars (1916–1947)
- Composition: 90% silver, 10% copper

How Much Silver is in Constitutional Silver?
When it comes to constitutional silver, the exact silver weight varies depending on the denomination. However, a standard rule of thumb is:
- $1.40 face value of 90% silver coins ≈ 1 troy ounce of silver.
This makes it easier to estimate how much silver you have without weighing every coin. For example:
- $1 face value in dimes, quarters, or half-dollars = 0.715 troy ounces of silver.
- $10 face value in these coins = 7.15 troy ounces of silver.
How to Calculate the Value of Constitutional Silver
One of the most common questions collectors and investors ask is: “How do I figure out what my constitutional silver is worth?”
Here’s the formula:
(Spot Price of Silver ± Premium) × 0.715 = Value per $1 Face Value
- Spot Price: The current market price of silver.
- Premium: Dealer markup or discount, depending on the market.
- 0.715: The average silver content (in troy ounces) of $1 face value of circulated 90% silver coins.
Example Calculation:
If silver is $25 per troy ounce and premiums are +$2:
($25 + $2) × 0.715 = $19.39 per $1 face value.
That means a $10 roll of silver dimes would be worth about $193.90 at that silver price and premium.
Why Collectors and Investors Like Constitutional Silver
There are several reasons why constitutional silver remains popular today:
- Recognizable & Trusted: U.S. coins are widely recognized and trusted for their authenticity.
- Fractional Silver: Small denominations make it easy to buy, sell, or trade in fractional amounts.
- Historic Value: These coins carry history, artistry, and collector interest beyond their silver content.
- No 1099 Reporting Thresholds: Unlike some bullion products, selling constitutional silver in small amounts generally doesn’t trigger tax reporting.
- Hedge Against Inflation: Silver protects purchasing power when paper money loses value.
Is Constitutional Silver Better Than Bullion?
This is a common debate among investors. Bullion rounds and bars have straightforward silver weights, but constitutional silver offers unique advantages:
- It’s government-minted legal tender, not private mint bullion.
- It provides smaller denominations, useful for barter scenarios.
- It’s often more affordable in small quantities, since collectors and dealers frequently trade in face-value lots.
That said, bullion bars and coins may carry lower premiums per ounce when buying larger quantities. The choice depends on whether you value flexibility (constitutional silver) or efficiency (bullion).
FAQs About Constitutional Silver
Q: Is “junk silver” the same as constitutional silver?
Yes—both terms refer to 90% silver U.S. coins, but many prefer the term “constitutional silver” because it doesn’t imply worthlessness.
Q: What years of coins qualify as constitutional silver?
Generally, all dimes, quarters, and half-dollars minted in 1964 or earlier.
Q: Does condition matter?
For most constitutional silver, condition matters less than silver weight. Exception: rare dates or mintmarks (like key-date Mercury dimes or Standing Liberty quarters) can carry numismatic premiums.
Q: How should I store constitutional silver?
Most collectors keep their coins in tubes, rolls, or bags. Because they’re circulated coins, fancy storage isn’t required, but keeping them dry helps prevent toning.
