Valuable U.S. Half Dollars Collectors Should Know
First, What Makes a Half Dollar Valuable?
A half dollar can be worth more than face value for several reasons: silver content, low mintage, a scarce mint mark, a recognized die variety, or unusually high grade. Silver alone can make older half dollars worth saving, but the largest premiums usually come from date, grade, and authentication.
This list focuses on U.S. half dollars collectors commonly search for and can identify with dates, mint marks, and basic diagnostics. It is not a promise of value. A cleaned, damaged, or fake coin can be worth far less than a problem-free certified example.
10 Valuable Half Dollars Worth Knowing
1. 1916-S Walking Liberty Half Dollar
The 1916-S is a first-year Walking Liberty half dollar from San Francisco. It is a better date because of its low mintage and strong collector demand. Check for the S mint mark on the obverse under "In God We Trust," since early Walking Liberty mint mark placement is different from many later coins.
2. 1921 Walking Liberty Half Dollar
The 1921 Philadelphia Walking Liberty half dollar has one of the lowest mintages in the series. A circulated coin can still bring a strong premium, while problem-free high-grade examples are much more expensive.
3. 1921-D Walking Liberty Half Dollar
The 1921-D is another major Walker key date. The D mint mark is on the reverse, and collectors pay attention to both originality and strike quality. Counterfeit or altered coins are possible, so certification matters on higher-value examples.
4. 1921-S Walking Liberty Half Dollar
The 1921-S is one of the most famous Walking Liberty half dollars. PCGS lists a mintage of 548,000 and calls it the key date of the series, especially as grade rises. In Mint State, it becomes a serious collector coin.
5. 1938-D Walking Liberty Half Dollar
The 1938-D is a later-date Walking Liberty key with a mintage under half a million. It is famous because nice examples were saved, but the coin is still heavily collected and can become expensive in top grades.
6. 1948 Franklin Half Dollar With Full Bell Lines
The first-year Franklin half dollar is not rare in ordinary circulated condition, but strong Mint State coins with Full Bell Lines can carry a much larger premium. Look at the Liberty Bell on the reverse. The horizontal bell lines must be sharp and uninterrupted for the FBL designation.
7. 1955 Franklin "Bugs Bunny" Half Dollar
The 1955 Bugs Bunny Franklin half is a recognized die variety where a clash mark near Franklin's mouth can make it look like he has buck teeth. The strongest values usually come from certified coins with strong grade and Full Bell Lines.
8. 1964 Kennedy Accented Hair Proof Half Dollar
The 1964 Accented Hair Kennedy half dollar is a proof-only variety. It shows extra hair detail above Kennedy's ear and often has a missing lower-left serif on the I in LIBERTY. It should be a proof coin, not a normal circulation strike.
9. 1970-D Kennedy Half Dollar
The 1970-D Kennedy half dollar was only sold in Mint Sets, and PCGS notes it was the last business-strike Kennedy half dollar containing silver. It is 40% silver, not 90%, and is one of the modern Kennedy dates collectors specifically pull aside.
10. 1998-S Matte Finish Kennedy Half Dollar
The 1998-S matte finish Kennedy half dollar was sold in a special collector set with the Robert F. Kennedy commemorative silver dollar. NGC describes it as the only silver matte finish Kennedy half and the lowest-mintage Kennedy half dollar, with about 62,000 sold.
How To Check Your Half Dollars
- Start with the date and mint mark. A normal 1971-D is not the same kind of find as a 1970-D.
- Check the edge. Silver half dollars often show a different edge color than copper-nickel clad coins.
- Weigh the coin if the value seems high. Many classic silver half dollars weigh 12.50 grams, while 40% silver Kennedy halves weigh 11.50 grams.
- Look for cleaning, scratches, rim damage, or artificial toning. Problems can cut the value sharply.
- For rare dates and major varieties, use PCGS or NGC authentication before selling or buying at a premium.
Common Mistakes To Avoid
Do not assume every old half dollar is rare. Many Franklin halves and common-date Walking Liberty halves trade mostly on silver value unless the grade is unusually strong. Also, do not confuse a 1964 regular Kennedy half dollar with the 1964 Accented Hair proof variety. The variety is a proof issue with specific diagnostics, not just any 1964 Kennedy half.
