The 1973-S Kennedy Half Dollar is worth anywhere from $3 in typical proof condition to over $12,000 for rare high-grade specimens. While most found in old collections are common, certain “deep cameo” versions and high-end grades carry significant premiums for everyday treasure hunters.
| Condition | Estimated Value |
|---|---|
| Proof-65 (Standard) | $3 – $5 |
| Proof-69 Deep Cameo | $25 – $40 |
| Proof-70 Deep Cameo | $150 – $350 |
| Rare Double Die Error | $50 – $500+ |
History and Significance of the 1973-S Kennedy Half Dollar
By 1973, the Kennedy Half Dollar had become a staple of American currency, though it was rarely seen in actual circulation. This specific year holds a unique place in the series because the San Francisco Mint (noted by the “S” mint mark) exclusively produced Proof coins for collectors. Unlike the Philadelphia and Denver mints, which pumped out millions of coins for the pockets of everyday Americans, San Francisco focused on quality over quantity.
To accurately identify your coin and its specific minting characteristics, you might want to use the best coin identifier app to ensure you aren’t overlooking a valuable mint mark. Many people find these coins in “Proof Sets”—those plastic-encased collections sold by the US Mint.
The 1973-S was struck using specially polished dies and planchets (coin blanks). This process produces a mirror-like background and frosted details on President John F. Kennedy’s portrait. While over 2.7 million were made, finding one that has survived without scratches or “fogging” is the key to unlocking real value. Using an app like CoinHix can help you distinguish between a standard strike and a high-quality Proof.
Understanding the Price Factors for the 1973-S Half Dollar
When determining the value of your 1973-S, the most important factor is the “Cameo” effect. In the early 1970s, the minting process for proofs was transitioning. The very first coins struck with new dies had a heavy frosting on the design and a deep mirror finish on the fields. These are known as “Deep Cameo” or “Ultra Cameo” coins.
Later strikes from the same dies lost this contrast, resulting in “Cameo” or “Brilliant” finishes. Collectors pay a massive premium for the Deep Cameo (DCAM) variety because they are visually stunning and much harder to find in perfect condition. For a detailed breakdown of how condition affects the market, you can check the 1973 Kennedy Half Dollar price trends by grade.
The following table illustrates how the price jumps significantly as the quality moves toward perfection:
| Grade (PCGS/NGC) | Cameo Value | Deep Cameo Value |
|---|---|---|
| PR 67 | $6 | $12 |
| PR 68 | $10 | $18 |
| PR 69 | $15 | $35 |
| PR 70 | $120 | $350+ |
Does the 1973-S Half Dollar Contain Silver?
This is the most common question asked by people who find old half dollars. Unfortunately, for those looking to “strike it rich” on precious metals alone, the 1973-S Kennedy Half Dollar is made of a Copper-Nickel clad composition. The US Mint stopped using 90% silver in 1964 and moved to 40% silver for Kennedy halves between 1965 and 1970.
By 1971, all circulating half dollars and standard proof sets were transitioned to a base metal mix. If you have a 1973-S, it will have a distinct copper stripe on its edge. If the edge is solid silver/white, you might have an extremely rare experimental strike or an error, but 99.9% of the 1973-S coins are clad.
Even without silver content, these coins are popular in the numismatic market. You can find more comprehensive 1973-S value information to see how they stack up against the silver years. While they don’t have melt value, their “collector value” is what you should focus on. Tools like CoinHix are excellent for organizing your collection and tracking which years are silver versus clad.
Rare Errors and Varieties to Look For
While most 1973-S halves are standard, professional hunters look for “Double Die” errors. A doubled die occurs when the coin is struck by a die that has a shifted image. On a 1973-S, you should look closely at the lettering of “LIBERTY” and the date “1973.” If you see clear doubling of the lines, you could be holding a coin worth hundreds of dollars.
Another rare occurrence is the “No S” error, though it is more famous in other years like 1968 or 1975. While a 1973-S without an “S” hasn’t been widely documented as a major rarity like the 1975, minting anomalies happen. Always check the area just above the date to confirm the “S” mark is crisp and clear.
| Error Type | Visual Indicator | Potential Value |
|---|---|---|
| Doubled Die Obverse | Thickening/Double lines in LIBERTY | $50 – $200 |
| Repunched Mint Mark | Shadowing around the “S” | $20 – $50 |
| Strike-Through | Foreign material pressed into surface | $15 – $100 |
Why the PR70 Grade is the “Holy Grail”
In the world of coin collecting, “70” is the perfect score. It means that under 5x magnification, the coin has no visible scratches, spots, or imperfections. Finding a 1973-S in PR70 Deep Cameo is incredibly difficult. Even though they were protected in plastic cases by the Mint, many developed “milk spots” or hazy toning over the decades due to the packaging materials.
If you have a coin that looks flawless, it might be worth sending to a grading service like PCGS or NGC. A PR69 might only sell for $30, but that single point jump to PR70 can push the price into the hundreds. Always use CoinHix to compare your coin’s luster with high-resolution photos of graded examples before spending money on professional grading fees.
The market for perfect 70s is volatile but strong. Registry set collectors—people who compete to have the finest known collection of a specific series—will often pay a premium to get the highest possible grade for their 1973 set.
How to Store and Protect Your 1973-S Kennedy Half Dollar
If you’ve discovered that your coin is in excellent condition, you must protect it immediately. The oils from your skin can cause “fingerprint” corrosion on Proof coins, which permanently ruins their value. Always handle your half dollars by the edges, or better yet, use cotton gloves.
The best storage method is a PVC-free plastic flip or a hard plastic “slab.” Avoid using old cardboard folders that contain sulfur, as these will cause the 1973-S to turn a dark, unattractive color over time. Keeping your coins in a cool, dry place will ensure that they maintain their mirror-like finish for the next generation of collectors.
| Storage Type | Pros | Cons |
|---|---|---|
| Original Government Packaging | Keeps set together, Historical | Can cause “haze” or toning |
| Hard Plastic Capsules | Superior protection against drops | Takes up more space |
| Professional Grading | Guarantees grade and authenticity | Expensive ($30+ per coin) |
1973-S Kennedy Half Dollar FAQ
Q: Is my 1973-S half dollar made of silver?
A: No, the 1973-S Kennedy Half Dollar is a clad coin made of a copper core and a nickel-copper outer layer. The last 40% silver half dollars were struck for general release in 1970.
Q: Where is the mint mark on a 1973-S half dollar?
A: The mint mark is located on the “obverse” (front) of the coin. You can find the small “S” just above the mid-point of the date “1973,” right below the truncation of Kennedy’s neck.
Q: Can I find a 1973-S in my pocket change?
A: It is very rare but possible. Since 1973-S coins were only issued in Proof Sets, one would only be in circulation if someone broke it out of its plastic case and spent it. If you find one in change, it will likely be scratched and “impaired,” meaning it is only worth its 50-cent face value or a small premium to a casual collector.
Q: What makes a 1973-S “Deep Cameo”?
A: A Deep Cameo (DCAM) coin has a very strong contrast between the frosted, white-looking features of Kennedy’s portrait and the dark, mirror-like background. This effect is most prominent on the first few hundred coins struck from a fresh pair of dies.
Q: How much is a 1973-S Proof Set worth?
A: A full 1973 Proof Set, which includes the cent, nickel, dime, quarter, and the half dollar, usually sells for between $7 and $15 depending on the condition of the coins and the outer box. Most of the set’s value is often tied to the 1973-S Half Dollar and the 1973-S Washington Quarter.
