Finding an old half dollar can spark immediate curiosity: how much are US half dollars worth? While many circulating 50-cent pieces hold only their face value, some historic issues are genuine treasures. Identifying these valuable half dollars isn't just about luck; it's about knowing what specific characteristics to look for.
This guide dives deep into the factors that determine a half dollar's worth, moving beyond face value to uncover the hidden potential in your pocket change or collection. You'll learn the key indicators that transform a common coin into a collector's prize.
At a Glance: Key Takeaways for Half Dollar Value
- Silver Content is King: The quickest way to spot value is checking the mint date for silver.
- Pre-1965: All half dollars from 1964 or earlier are 90% silver and inherently valuable.
- 1965-1970: Kennedy half dollars from these years contain 40% silver, still worth more than face value.
- Key Dates & Mint Marks: Beyond silver, certain dates and mint marks signify rarity, driving prices even higher.
- Coin Condition Matters Most: The "grade" of a coin can dramatically increase its value, sometimes by hundreds of dollars.
- Professional Appraisal: For true valuation, especially for rare or high-grade examples, expert assessment is crucial.
The Silver Standard: Your First Step to Uncovering Value
When you hold an old half dollar, your first question should always be about its silver content. This is the most straightforward and often the most significant factor determining how much US half dollars are worth. Silver adds intrinsic value, meaning the coin is worth at least its melt value, which is almost always far more than 50 cents.
The 90% Silver Era: Pre-1965 Gems
If your half dollar is dated 1964 or earlier, congratulations—you likely have a valuable coin. These coins are struck from 90% pure silver. This category includes iconic designs like the Walking Liberty Half Dollars (1916-1947) and the Franklin Half Dollars (1948-1963), as well as the first-year Kennedy Half Dollars (1964).
Think of it this way: even a heavily worn 90% silver half dollar will be worth many times its face value simply for its metal content. The exact price fluctuates with the market price of silver, but it’s a constant baseline of value that makes these coins highly desirable.
- Example: A 1950 Franklin Half Dollar, even in average circulated condition, is primarily valued for its 90% silver. If silver is trading at $25 an ounce, that coin's melt value alone could be over $9-$10, regardless of its design or specific date.
The 40% Silver Era: The Kennedy Transition (1965-1970)
The mid-1960s saw a shift in US coinage compositions due to rising silver prices. Kennedy Half Dollars minted between 1965 and 1970 are distinct because they contain 40% silver. While not as pure as their pre-1965 counterparts, these "silver-clad" coins still carry a premium over their 50-cent face value.
Many people overlook these 40% silver half dollars, assuming only pre-1965 coins have silver. This makes them a potential sleeper find. Collectors often seek them out to complete sets or simply for their silver bullion value.
- Case Snippet: Imagine finding a roll of old half dollars and noticing a 1967 Kennedy. While not as heavy as a 1964, its slight silver gleam and a quick date check confirm its 40% silver content, immediately elevating its value beyond face.
The Copper-Nickel Era: 1971 to Today
For the vast majority of half dollars minted from 1971 to the present, silver content is largely absent. These coins are made from a copper-nickel composition, which is durable and cost-effective but lacks intrinsic metal value beyond its face denomination.
There are very few exceptions, primarily special proof sets intended for collectors, which sometimes include silver versions of modern dates. However, standard circulating half dollars from this period are typically worth only 50 cents. So, if your coin is dated 1971 or later, and it wasn't part of a special collector's set, its primary value is usually as spendable currency.
Rule of Thumb: If your half dollar is dated 1970 or earlier, you've likely found a coin worth more than 50 cents due to its silver content.
Beyond Silver: Key Dates, Mint Marks, and Varieties
While silver content provides a baseline value, certain half dollars command much higher prices due to their rarity, specific mint marks, or unusual varieties. These are the "key dates" and "semi-key dates" that collectors actively pursue.
Walking Liberty Half Dollars (1916-1947)
This elegant design is beloved by collectors, and many dates within the series are highly collectible. Beyond their 90% silver content, certain Walking Liberty half dollars are particularly scarce.
- Key Dates to Watch For:
- 1916-S: A low mintage coin from the series' inaugural year, especially scarce.
- 1921: Another very low mintage issue, tough to find in any condition.
- 1921-D: The Denver Mint's 1921 production was extremely limited, making this a significant rarity.
Even in lower grades, these key dates can be worth hundreds, if not thousands, of dollars.

Franklin Half Dollars (1948-1963)
Franklin half dollars are generally valued for their 90% silver content. However, a few specific issues stand out for their additional numismatic premium.
- Key Dates/Varieties to Watch For:
- 1949-S: A lower mintage issue from the San Francisco Mint.
- 1955: Another date with a relatively low mintage compared to surrounding years.
These specific Franklins, especially in higher grades, will sell for more than their silver melt value alone, appealing to collectors aiming to complete a full set.
Kennedy Half Dollars (1964-Present)
While many Kennedy Half Dollars from 1964-1970 are valuable for their silver, one date stands out for its scarcity beyond metal content.
- Key Dates to Watch For:
- 1970-D: This is a crucial key date because the 1970-D Kennedy Half Dollar was only issued in mint sets. It was never released into general circulation. This makes it significantly scarcer than other post-1964 issues, and it holds a strong premium for collectors even though it's 40% silver. Finding one of these outside of its original mint packaging is a rare and exciting discovery.
Understanding Mint Marks
Mint marks are small letters (D, S, P, O, CC) found on coins that indicate where they were produced (Denver, San Francisco, Philadelphia, New Orleans, Carson City). Their presence and location can affect a coin's rarity and value. For example, a "D" mint mark on a 1970 Kennedy is what makes it rare, as opposed to if it were a "P" (Philadelphia, which didn't produce them for circulation that year). Always check for these small details.
The Condition Equation: Why Grade is Everything
Imagine two identical 1940 Walking Liberty Half Dollars. One is heavily worn, details are smoothed away, and it's covered in scratches. The other is pristine, with sharp details, original luster, and no signs of circulation. While both contain the same amount of 90% silver, the perfectly preserved coin could be worth hundreds, or even thousands, more than its worn counterpart.
This difference highlights a critical factor: the coin's condition, or "grade," is often the biggest determinant of its final value.
How Condition Magnifies Value
Coin grading is a complex discipline that assesses a coin's wear, luster, strike quality, and surface preservation. Professional grading scales range from "Poor" (P-1) to "Perfect Uncirculated" (MS-70).
- Circulated vs. Uncirculated: A coin that has been handled and spent time in circulation ("circulated") will show wear. An "uncirculated" coin (often abbreviated as "Mint State" or MS) shows no signs of wear and retains its original mint luster. The jump in value from a high-grade circulated coin to a low-grade uncirculated coin can be substantial.
- The Power of Luster: Original mint luster, the cartwheel effect seen on uncirculated coins, is a key component of high grade and often commands a significant premium.
- Strike Quality: How well the design elements are impressed onto the coin also plays a role. A "full strike" with sharp details is more desirable than a weak strike.
The Nuances of Professional Grading
Accurately grading a coin requires years of experience and a deep understanding of numismatics. Subtle differences in wear, contact marks, and toning can mean hundreds of dollars in value difference. This is why professional coin appraisal and grading services (like PCGS or NGC) are so vital for valuable coins.
- Practical Example: A common-date 90% silver Franklin Half Dollar in average circulated condition might sell for $10-$15 based on silver prices. However, the exact same date and mint mark in a perfect, professionally graded "Mint State 65" (MS-65) condition could easily be worth $100-$300 or more, simply because of its superior preservation and eye appeal.
Attempting to clean a coin to improve its appearance is a common and often disastrous mistake. Cleaning almost always reduces a coin's numismatic value, as it removes original surfaces and luster, which are key to high grades. Always consult an expert before attempting any form of "restoration."
Your Practical Playbook: How to Evaluate Your Half Dollar
Ready to assess your own half dollars? Here's a step-by-step guide to help you determine how much your US half dollars are worth and identify potential valuable ones.
- Check the Date Immediately: This is your absolute first step.
- 1964 or Earlier: Automatically valuable for 90% silver. Set aside.
- 1965-1970: Automatically valuable for 40% silver. Set aside.
- 1971 or Later: Likely face value unless it's a known silver proof set exception (which are rare in circulation). Still, give it a quick check for anything unusual, but prioritize the older dates.
- Locate the Mint Mark: If your coin is a potential silver valuable or a key date.
- Walking Liberty (1916-1947): Mint mark typically on the reverse, below the branch.
- Franklin (1948-1963): Mint mark above the bell on the reverse.
- Kennedy (1964-Present): Mint mark on the reverse (1964-1967), then on the obverse above the date (1968-Present).
- Check for the specific key dates and mint marks mentioned earlier (e.g., 1916-S, 1921-D, 1970-D).
- Assess Condition (Preliminary):
- Very Worn: Details are smooth, date might be hard to read. Value will be primarily melt value for silver coins, or near face for non-silver.
- Moderate Wear: Most details are visible, but high points show clear wear. Still decent value for silver.
- Slight Wear/No Wear: Details are sharp, some luster might be present. This is where professional grading becomes important. Handle by the edges to avoid damaging the surface.
- Compare Against Known Values: Once you've identified the date, mint mark, and a rough condition, you can consult reputable coin price guides (online or in print) to get an estimated value range. Remember, these are estimates, and actual selling prices can vary.
- Consider Professional Appraisal for Key Finds: If you believe you have a key date, a rare variety, or a silver coin in exceptionally high-grade condition, resist the urge to clean it. Seek a professional numismatist or send it to a third-party grading service (like PCGS or NGC) for an expert opinion and certification. This is especially true for any coin potentially worth hundreds of dollars or more.
Quick Answers: Common Questions About Half Dollar Value
Are Bicentennial Half Dollars (1776-1976) valuable?
Most Bicentennial half dollars you find in circulation are made of copper-nickel and are worth only 50 cents. Like other coins from 1971 onwards, silver versions were produced for special collector sets, but these are rarely found in change. Unless you have a silver proof version (easily identified by its slightly duller, distinct silver appearance and often found in original government packaging), it's likely face value.
What's the difference between 90% silver and 40% silver half dollars?
The primary difference is the silver content. 90% silver coins (1964 and earlier) are solid silver alloy, making them heavier and brighter. 40% silver coins (1965-1970) are a "sandwich" of copper with outer layers of 80% silver, giving them a lighter weight and a slightly different metallic sheen. Both are worth more than face value, but 90% silver coins have significantly higher melt value.
Can I clean my old half dollar to make it more valuable?
Absolutely not. Cleaning a coin almost always reduces its numismatic value. It removes the original surface, luster, and toning, which are crucial elements of its grade and appeal to collectors. What looks like dirt or tarnish to an amateur eye might be natural patina that collectors highly value. Leave the coin as-is.
How do I know if my coin is a "proof" coin?
Proof coins are specially struck for collectors, often with polished dies and planchets, resulting in a mirror-like field and frosted design elements. They are typically found in special government sets and are not meant for circulation. If your coin has an exceptionally reflective, almost mirrored background, it might be a proof. However, circulation wears this effect away quickly.
Where can I sell my valuable half dollar?
Reputable options include local coin dealers, online coin auction sites, or through professional auction houses for very high-value pieces. Always get multiple opinions or bids if possible. For certified coins, the market is much more transparent.
Taking Action: Unlocking Your Half Dollar's True Potential
Understanding how much US half dollars are worth is a journey from simple curiosity to informed appraisal. Your immediate action should always be to identify the coin's date and then its potential silver content. This quickly sorts most half dollars into "face value" or "more than face value" categories.
From there, delve into the specifics: mint marks, key dates, and crucially, the coin's condition. For any half dollar you suspect might be genuinely valuable—beyond simple melt value—your next, and most important, step is to seek expert verification. A professional numismatist can provide accurate grading and valuation, ensuring you understand the true market potential of your find without risking damage or misidentification. Happy hunting!
