Do you ever wonder if the old US coins in your possession are actually silver? It can be confusing, and you might miss out on hidden value or overpay for common coins. This guide will help you easily identify which American coins contain real silver.

Many US dimes, quarters, and half dollars made before 1965 are 90% silver¹. Kennedy half dollars² from 1965 to 1970 contain 40% silver. Dollar coins minted in 1935 or earlier are also 90% silver.

So, you know some US coins are silver. But which ones exactly, and how much silver do they contain? The story involves specific dates and types of coins. Before 1965, the United States used silver in its circulating coins because it was durable and had intrinsic value. But as the price of silver metal increased, it became too expensive to keep using it in everyday money. This led to a big change in how coins were made. Knowing the cutoff dates and the specific coins involved is key to spotting silver.

Understanding the history helps identify these coins. The US Mint produced coins with 90% silver content for many years. This standard was applied to most denominations except for pennies and nickels.
Here's a breakdown of the common US coins that contain silver:

1. Dimes: Roosevelt dimes and Mercury dimes dated 1964 and earlier are 90% silver. If you find dimes with these earlier dates, they have silver content.
2. Quarters: Washington quarters dated 1964 and earlier are 90% silver. Standing Liberty quarters and Barber quarters (older designs) are also 90% silver. The date is the easiest first check.
3. Half Dollars: Franklin halves and Walking Liberty halves (dated 1964 and earlier) are 90% silver. Kennedy half dollars have a split history: those dated 1964 are 90% silver, but those dated 1965-1970 are only 40% silver. Half dollars from 1971 onwards (circulating versions) contain no silver.
4. Dollars: Morgan dollars and Peace dollars, minted in 1935 and earlier, are 90% silver. Later dollar coins, like the Eisenhower dollar, had special collector versions containing 40% silver (usually marked 'S' for San Francisco mint), but the ones intended for circulation were silver-free.
5. "War Nickels³": There's one exception for nickels. Jefferson nickels minted between 1942 and 1945 with a large mint mark (P, D, or S) above Monticello on the reverse side contain 35% silver. This was done to save nickel for the war effort during World War II. Regular nickels before or after these dates have no silver.

Knowing these specific coins and dates is the foundation for finding silver in your change or collection. It's less about complex analysis and more about checking the date and type.

How Can You Tell if a US Coin is Silver?

Finding silver coins can be exciting. But how do you quickly check a coin you just found? Luckily, there are simple ways.

Check the date first. Dimes, quarters, and half dollars dated 1964 or earlier are likely 90% silver. Also, look at the coin's edge. If it's a solid silver stripe without a copper-red line, it's probably silver.

Beyond just knowing the types and dates, a few simple tests can help confirm if a US coin is silver, especially when sorting through many coins. These methods don't require special equipment, making them handy for anyone.

Simple Tests for Silver Coins

Here are a few reliable methods you can use:

The Date Test

• Rule: This is your primary check. For dimes, quarters, and half dollars, the key year is 1964. If the date is 1964 or earlier, it's highly likely 90% silver.
• Exception: Kennedy Half Dollars dated 1965-1970 are 40% silver.
• War Nickels: Dates 1942-1945 with a large mint mark (P, D, or S) on the reverse are 35% silver.

The Edge Test

• How it works: Look at the thin edge or rim of the coin.
• Silver Coins: 90% silver dimes, quarters, and halves minted in 1964 or earlier will show a solid silver stripe along the edge.
• Clad Coins: Coins made after the switch (most dimes and quarters from 1965 onwards, half dollars from 1971 onwards) are "clad." They have layers of copper-nickel sandwiching a core of copper. This copper core is visible as a reddish-brown stripe on the edge.
• 40% Silver Coins: Kennedy halves (1965-1970) and silver Eisenhower dollars have a mix. Their edge might look less distinctly copper-red than modern clad coins, sometimes appearing grayish, but it won't be the solid silver stripe of the 90% coins.

The Sound Test (The "Silver Ring")

• Method: Gently balance the coin on your fingertip and tap it with another coin.
• Silver Sound: Silver coins tend to produce a higher-pitched, longer-lasting ringing sound compared to clad coins.
• Clad Sound: Clad coins usually make a duller, shorter "thud" sound.
• Caution: This test is subjective and less reliable than the date and edge tests. It takes practice to distinguish the sounds accurately. Wear and tear on the coin can also affect the sound.

Weight Comparison

• Principle: Silver is denser than the copper-nickel alloy used in clad coins.
• Example: A 90% silver Washington quarter (pre-1965) weighs 6.25 grams. A clad Washington quarter (1965 onwards) weighs 5.67 grams.
• Usefulness: This requires a precise scale. It's more accurate but less practical for quick sorting than the visual edge test.

Using the date and edge tests together is usually the most effective way for most people to quickly identify silver coins.

Are ALL Pre-1965 Coins Silver?

It's a common question I hear: "If a coin is old, say before 1965, does that automatically mean it's silver?" This idea needs clarification.

No, not all US coins made before 1965 contain silver. Pennies (cents) and regular nickels were primarily made of copper or copper-nickel, not silver. The silver rule mainly applies to dimes, quarters, half dollars, and dollar coins.

While 1964 is the magic year for dimes, quarters, and half dollars switching from 90% silver, it's important to remember the specific denominations involved. The assumption that all older coins have silver is incorrect and can lead to disappointment.

Which Pre-1965 Coins are NOT Silver?

Let's break down why this misconception exists and which coins are excluded:

Focus on Specific Denominations

• Pennies (Cents): US cents have never been made of silver. Historically, they were primarily copper (until 1982, with some exceptions like the 1943 steel cent) and are now mostly zinc with copper plating. So, an old penny, even from the 1800s, isn't silver.
• Nickels (Five Cents): Standard Jefferson nickels, Liberty Head nickels, and Buffalo nickels were made of a 75% copper, 25% nickel alloy. They contain no silver, except for the specific "War Nickels."

The Exception: War Nickels (1942-1945)

• As mentioned earlier, during World War II, nickel was needed for military applications.
• To conserve this metal, the composition of the five-cent piece was changed temporarily to an alloy of 56% copper, 35% silver, and 9% manganese.
• Identification: These War Nickels are easily identified by their dates (mid-1942 through 1945) AND a large mint mark (P, D, or S) placed prominently above the dome of Monticello on the reverse side. Nickels from this period without the large mint mark are not silver.

Distinguishing Circulation Coins from Non-Circulating Silver

• The discussion so far has centered on coins intended for general circulation.
• The US Mint also produces modern commemorative coins and bullion coins (like the American Silver Eagle series, which started in 1986) that are made of silver (often .999 fine silver).
• These are generally not found in everyday pocket change and are targeted at collectors and investors. Pre-1965 circulation coins are silver because that was the standard material at the time, not because they were special editions.

So, when checking old coins, remember the rule applies mostly to dimes, quarters, halves, and dollars. Always exclude pennies and regular nickels from your silver hunt list.

What is the Difference Between 90% and 40% Silver Coins?

You might hear people talk about "90% silver" junk coins or "40% silver" Kennedys. Understanding this difference is important for collectors and stackers.

90% silver coins (most US dimes, quarters, halves dated 1964 or earlier, and dollars 1935 or earlier) contain 90% silver and 10% copper. 40% silver coins (Kennedy Halves 1965-1970) have a silver-copper clad composition totaling 40% silver.

The percentage refers directly to the amount of pure silver content by weight in the coin. The US Mint used different alloys over time, mainly due to the rising cost of silver. The shift from 90% to 40% was a significant step in phasing silver out of circulating coinage altogether.

Comparing Silver Content

Let's explore these two common types of US silver coinage:

90% Silver ("Constitutional Silver")

• Composition: These coins are made of an alloy containing 90% silver and 10% copper. The copper was added primarily to make the coins harder and more durable for circulation.
• Examples:
  • Dimes (Mercury, Roosevelt): 1964 and earlier
  • Quarters (Standing Liberty, Washington): 1964 and earlier
  • Half Dollars (Walking Liberty, Franklin, Kennedy): 1964
  • Dollars (Morgan, Peace): 1935 and earlier
• Why "Constitutional Silver"? This informal term is often used because the silver content was mandated by US law (Coinage Act) for these denominations for a long period.
• Value: Their melt value is directly tied to the spot price of silver and their higher silver content makes them more valuable (ounce for ounce) than 40% coins.

40% Silver ("Silver Clad")

• Composition: These coins have outer layers composed of 80% silver and 20% copper, bonded to an inner core of 20.9% silver and 79.1% copper. The total composition nets out to 40% silver by weight.
• Examples:
  • Kennedy Half Dollars: 1965, 1966, 1967, 1968, 1969, 1970
  • Eisenhower Dollars (Collector Versions): Certain "Ike" dollars minted between 1971-1976, typically bearing the 'S' mint mark (San Francisco), were made with 40% silver for collectors, distinct from the copper-nickel clad circulating versions.
• Reason for Change: Introduced as a transitional measure after the Coinage Act of 1965 to reduce the amount of silver used while still maintaining some silver presence, particularly in the popular half dollar denomination.
• Value: They still contain silver and have melt value, but significantly less than their 90% counterparts of the same face value. It takes more 40% silver coins to equal the same amount of silver found in 90% coins.

Understanding this distinction helps you accurately assess the potential value of silver coins you might find or consider purchasing.

Why Did the US Stop Making Silver Coins for Circulation?

The switch from silver coins to the clad coins we use today wasn't random. There were powerful economic forces behind this major change in American currency.

The US stopped making silver coins mainly because the value of the silver metal in the coins rose above their face value by the early 1960s. This led people to hoard silver coins, causing shortages in circulation.

It boils down to simple economics. When the metal in a coin is worth more than the number stamped on it, people will save the coins rather than spend them. This created significant problems for the US economy and monetary system.

The End of an Era for Silver Coinage

Several factors converged to force the transition away from silver:

Rising Silver Prices

• Throughout the late 1950s and early 1960s, the global demand for silver increased for industrial uses (like photography and electronics) and investment purposes.
• This rising demand pushed the market price of silver upwards.
• Eventually, the value of the silver contained in dimes, quarters, and half dollars exceeded their face value. For example, the silver in ten dimes became worth more than one dollar.

Gresham's Law in Action

• This economic principle essentially states that "bad money drives out good."
• In this context, the "good" money was the silver coins (with high intrinsic value), and the "bad" money was paper currency or potentially soon-to-be-introduced clad coins (with value based only on government decree).
• People naturally chose to hoard the valuable silver coins and spend the less valuable paper money, removing silver coins from active circulation. This led to coin shortages, making everyday commerce difficult.

Government Response: The Coinage Act of 1965

• Facing widespread coin shortages and the reality of silver's high cost, the US government took action.
• President Lyndon B. Johnson signed the Coinage Act of 1965 into law.
• This act officially eliminated silver from dimes and quarters, replacing them with the copper-nickel clad composition still used today.
• It also reduced the silver content of the half dollar from 90% to 40% (effective from 1965 to 1970). Finally, even the 40% silver content was removed from circulating half dollars starting in 1971.

Impact on Circulation

• The transition was rapid. Once the new clad coins were introduced, the remaining silver coins quickly disappeared from circulation as people saved them for their metal value.
• Within a few years, finding a 90% silver coin in everyday change became a rare occurrence.

The decision to remove silver was primarily a practical response to economic pressures that made silver coinage unsustainable for a modern, high-volume economy.
