1973-S Kennedy Half Dollar Value: What Is Your Coin Worth?

The 1973-S Kennedy Half Dollar is worth anywhere from $3 in typical proof condition to over $12,000 for rare, high-grade specimens. Finding one of these shiny coins in a drawer or an inherited collection is exciting, as they were never intended for circulation and represent a special era of American coinage.

Condition/Grade	Estimated Value (USD)
PR65 (Standard Proof)	$3.00 – $5.00
PR69 Deep Cameo	$15.00 – $25.00
PR70 Deep Cameo (Perfect)	$120.00 – $250.00
Rare Mint Errors	$500 – $12,000+

Understanding the History of the 1973-S Kennedy Half Dollar

If you have stumbled upon a 1973 Kennedy half dollar with a small “S” mint mark, you are holding a piece of history from the San Francisco Assay Office. During the 1970s, the U.S. Mint produced millions of half dollars for general use in Philadelphia and Denver, but the San Francisco facility was reserved for “Proof” coins.

These coins were specifically created for collectors rather than for buying groceries or gas. For many Americans trying to identify a mystery find, using a top coin identifier and value app is the fastest way to confirm if their coin is a proof strike or a standard circulation strike.

The 1973-S is unique because it was part of a transitional period for the Mint. Unlike the half dollars from the mid-1960s, these coins do not contain any silver. They are made of a copper-nickel clad composition. Despite the lack of precious metal, their mirrors-like finish makes them stand out in any collection. When you use the CoinKnow app, you can instantly see the visual differences between a worn 1973-P and a high-quality 1973-S.

How to Identify a 1973-S Proof Kennedy Half Dollar

Identifying a 1973-S is relatively simple once you know where to look. The “S” mint mark is located on the obverse (front) of the coin, just above the date and below the neck of John F. Kennedy. If you see a “D,” it was made in Denver; no letter means it was made in Philadelphia.

The most striking feature of the 1973-S is its “Proof” finish. Proof coins are struck twice using specially polished dies and planchets (blanks). This results in a background (field) that looks like a mirror and raised details (devices) that often have a frosted, matte appearance.

If your coin looks exceptionally shiny compared to your pocket change, it is likely a proof. However, many of these coins were removed from their original plastic sets and spent time in circulation, which can dull their luster. To get an accurate reading on current market trends, you should check the latest 1973 Kennedy half dollar price data to see how scratches or wear might affect the bottom line.

Grading and the Impact of Deep Cameo Surfaces

In the world of coin collecting, the “Grade” is everything. For the 1973-S, graders look for the “Cameo” (CAM) or “Deep Cameo” (DCAM) effect. This refers to the contrast between the frosted portrait of JFK and the mirror-like background. A coin with a heavy frost and deep mirrors is highly coveted.

A coin graded PR65 is considered a mid-range proof and is quite common. However, as you move toward a perfect PR70 Deep Cameo, the price skyrockets because very few coins survived 50 years without a single microscopic scratch.

Numeric Grade	Designation	Typical Sale Price
PR 67	Cameo	$8 – $12
PR 68	Deep Cameo	$15 – $22
PR 69	Deep Cameo	$25 – $40
PR 70	Deep Cameo	$150 – $400

Using a tool like CoinKnow can help you compare your coin to high-resolution images of these different grades, giving you a better idea of whether it’s worth sending to a professional grading service like PCGS or NGC.

Rare 1973-S Varieties and Error Coins to Look For

While most 1973-S halves are worth only a few dollars, certain errors can make a coin worth thousands. One of the most legendary errors for this year involves coins struck on the wrong metal blanks. For example, a 1973-S half dollar struck on a silver-clad planchet (intended for the Eisenhower Dollar or leftover from 1970) would be a “holy grail” find.

Other common errors include “Double Dies,” where the letters or numbers appear to have a shadow or a second outline. While no major doubled die is widely recognized for the 1973-S proof specifically, collectors always keep an eye out for “clipped planchets” or “off-center strikes.”

If you suspect you have an error, analyzing the 1973 Kennedy half dollar value information can reveal what recent auction prices have been for authenticated errors. Often, an error coin in an otherwise “normal” collection is the difference between a $5 bill and a $500 payday.

Is the 1973-S Kennedy Half Dollar Silver?

This is the most common question asked by people who find old coins. The short answer is: No, the standard 1973-S Kennedy Half Dollar is not silver. Beginning in 1971, the U.S. Mint transitioned the half dollar to a “clad” composition consisting of 75% copper and 25% nickel bonded to a pure copper core.

If you look at the edge of the coin and see a distinct brownish or copper-colored stripe, it is definitely a clad coin. However, the Mint did produce 40% silver Kennedy halves between 1965 and 1970, and 90% silver halves in 1964 and again for special modern commemorative sets.

Since the 1973-S was only sold in proof sets to the public, it was never meant to be made of silver. For the average person, the value lies in the collector demand rather than the metal content. Checking your collection with CoinKnow can help you verify the composition based on the specific year and mint mark, ensuring you don’t overlook a potential silver rarity from a slightly different year.

Where to Sell Your 1973-S Kennedy Half Dollar

If you have determined that your 1973-S is a high-grade specimen or a rare error, you might be wondering how to turn it into cash. For common proofs (graded PR65 to PR68), your best bet is often an online marketplace like eBay or a local coin shop. However, be aware that a coin shop must make a profit, so they may offer you less than the “book value.”

For high-end PR70 coins or significant errors, professional auction houses like Heritage Auctions or GreatCollections are the preferred route. These venues attract serious collectors who are willing to pay a premium for “Registry Set” quality coins.

Before selling, always ensure your coin is protected in a PVC-free plastic holder. Touching the surface of a proof coin with your fingers can leave oils that permanently damage the mirror finish, significantly lowering the value.

FAQ

Q: Why is my 1973 half dollar shiny but has no “S” mint mark?

A: If it is shiny but lacks a mint mark, it was minted in Philadelphia. It might be a “Proof-like” business strike or simply a very well-preserved coin from a Mint Set. These are usually worth $1 to $3 in uncirculated condition.

Q: How many 1973-S Kennedy Half Dollars were made?

A: The U.S. Mint produced approximately 2.76 million 1973-S Proof Kennedy Half Dollars. While this sounds like a lot, it is a much lower mintage than the 100+ million business-strike coins made in Philadelphia and Denver that same year.

Q: Can I find a 1973-S in my pocket change?

A: It is rare, but it happens! Sometimes people crack open proof sets to spend the money, or “S” mint coins are accidentally mixed into circulation. These are called “Impaired Proofs” and are usually worth face value or a small premium to a curious collector.

Q: Is there a 1973-S Silver Half Dollar?

A: No official 1973-S silver half dollars were produced for general sale. Any silver 1973 half dollar would be an extremely rare transitional error struck on left-over 40% silver planchets. These must be professionally authenticated.
