The 1973 S Kennedy Half Dollar is worth anywhere from $3 in typical proof condition to over $1,200 for rare high-grade specimens. While most of these coins found in old collections are worth a few dollars, certain varieties and perfect strikes can command a significant premium from collectors.
Understanding the 1973 S Kennedy Half Dollar Proof
If you have found a 1973 Kennedy Half Dollar with an “S” mint mark, you are looking at a “Proof” coin. Unlike the coins you find in your pocket change, which were struck in Philadelphia or Denver for general circulation, the San Francisco Mint produced these specifically for collectors. These coins were struck using polished dies and specially prepared blanks to create a mirror-like finish.
To get an instant estimate of what your specific coin might be worth, you can use a top coin identifier app to analyze its condition. Because these coins were sold in protective plastic lenses as part of annual Proof Sets, many have survived in excellent condition. However, if your coin has been removed from its case and handled, its value may drop toward its copper-nickel melt value.
For those who are just starting their journey into coin collecting, the CoinHix app is an excellent tool to help you catalog your finds and track market fluctuations. Knowing whether your 1973-S is a standard proof or a “Deep Cameo” variant is the key to unlocking its true market potential.
The Difference Between Clad and Silver Kennedy Half Dollars
One of the most common questions people ask when they find an old half dollar is whether it contains real silver. By 1973, the United States Mint had fully transitioned away from silver for the Kennedy series. The 1973-S half dollar is a “clad” coin, meaning it is made of a core of pure copper bonded to outer layers of 75% copper and 25% nickel.
While earlier versions from 1964 and the 40% silver versions from 1965-1970 are valuable for their metal content, the 1973-S value is driven entirely by its condition and collector demand. You can easily check the edge of your coin; if you see a distinct copper stripe, it is a clad coin. Even without silver, a pristine specimen can still represent a solid investment for enthusiasts.
Professional appraisers often look for the “Deep Cameo” (DCAM) effect, where the frosted portrait of John F. Kennedy stands out sharply against a pitch-black, mirror-like background. If yours has this look, the 1973-S Kennedy half dollar market price for high-grade proofs reflects a much higher tier of value.
Grading and Value Chart for 1973 S Half Dollars
When determining the value of your coin, collectors use a scale from 1 to 70. For proof coins like the 1973-S, most fall between PR65 and PR69. A PR70 (a perfect coin) is exceptionally rare and can sell for hundreds or even thousands of dollars at auction. Most casual collectors will find their coins are in the PR65 to PR67 range.
To help you understand the current market, here is a breakdown of what you can expect to receive for a 1973-S Kennedy Half Dollar based on its professional grade:
| Coin Grade | Estimated Market Value |
|---|---|
| PR65 (Typical Proof) | $3.00 – $5.00 |
| PR67 (Higher Quality) | $8.00 – $12.00 |
| PR69 (Deep Cameo) | $25.00 – $45.00 |
| PR70 (Perfect Grade) | $1,250.00+ |
As you can see, the jump from PR69 to PR70 is massive. This is why many people use the CoinHix app to get a high-resolution look at their coins before deciding whether to pay for professional third-party grading.
Factors That Influence the 1973 S Half Dollar Worth
The three main factors influencing the price of your 1973-S are eye appeal, the level of “frosted” detail, and any potential mint errors. Eye appeal refers to how clean the surfaces are; even tiny hairline scratches caused by cleaning the coin with a cloth can significantly lower its value. Never clean your coins, as it removes the original mint luster and halves the value instantly.
The “Cameo” effect is the next big factor. In 1973, the minting process was not as consistent as it is today. Early strikes from a new die produced a heavy frost on Kennedy’s face, while later strikes from the same die looked more “brilliant” or shiny all over. Collectors pay much more for the “Deep Cameo” designation because it is more visually striking.
If you are looking for more detailed pricing on other mint marks from the same year, you can view the 1973 Kennedy half dollar value guide to see how the S-mint compares to the P and D versions. Generally, since P and D coins were meant for circulation, finding one in high grade is actually harder than finding a high-grade “S” proof.
Common Errors to Look For in 1973 Kennedy Half Dollars
While the 1973-S is primarily known as a collector’s proof, it isn’t immune to errors. Though rare in proof sets, some collectors have found coins with “doubled dies,” where the lettering or the date appears to be doubled. This happens when the hub strikes the die multiple times at slightly different angles.
Another error to look for is a “clipped planchet,” where the coin is missing a circular slice, or “missing clad layers,” which would make one side of the coin look bright red (copper) rather than silver. If you think you’ve found an error, the CoinHix community and database can help you compare your coin against known error varieties. Finding an authenticated error can turn a $3 coin into a $100 prize overnight.
Frequently Asked Questions
Q: Is the 1973-S Kennedy Half Dollar made of silver?
A: No, the 1973-S Kennedy Half Dollar is a clad coin made of copper and nickel. The US Mint stopped using 40% silver for standard half dollars after 1970.
Q: Where is the mint mark located on a 1973 half dollar?
A: The mint mark is located on the obverse (front) of the coin, just above the center of the date “1973.” You will see a small “S,” “D,” or no mark at all (which signifies Philadelphia).
Q: Should I get my 1973-S Half Dollar professionally graded?
A: Only if it appears to be in perfect condition. Since professional grading costs $20-$50 per coin, it is only worth it if the coin has a chance of grading PR69 Deep Cameo or PR70.
Q: Why is my 1973 half dollar worth only face value?
A: If it has a “P” or “D” mint mark and shows heavy wear from being used in stores, it is generally only worth its face value of 50 cents. Only the “S” proof versions or uncirculated coins carry a significant collector premium.
