What Makes Kennedy Half Dollars Valuable?
The Kennedy Half Dollar was minted as a tribute to President John F. Kennedy following his assassination in 1963. While millions of these coins were produced, certain unique features make some editions extremely valuable:
- Minting Errors: Unintentional flaws during production, such as doubling or missing elements.
- Low Mintage: Coins produced in limited numbers or under special circumstances.
- Unique Characteristics: Varieties like the “Accented Hair” design or those struck on silver planchets when others were not.
Collectors prize these coins not only for their monetary worth but also for the stories they tell about history and production techniques. Every detail in these coins provides a glimpse into the minting practices of the past and offers collectors an opportunity to own a tangible piece of history.
Additionally, the shift in composition from 90% silver in the earlier coins to copper-nickel in later years highlights changing economic conditions, further contributing to their allure.

How to Spot Valuable Kennedy Half Dollars
1. Use Proper Tools
Invest in a magnifying glass or jeweler’s loupe to inspect details like doubling, missing elements, or unique finishes. Digital microscopes are also an excellent option for detailed examination.
2. Check the Coin’s Edge
For coins like the 1970-D error, inspect the edge for a silver stripe, indicating a 40% silver composition. A lack of the copper core, commonly visible in modern coins, is another indicator.
3. Inspect the Obverse and Reverse
- Look for abnormalities in lettering, such as doubling or missing serifs.
- Examine the eagle’s tail feathers and surrounding area for missing initials or polishing marks.
4. Verify Weight
A standard Kennedy Half Dollar weighs 11.34 grams. Errors like the 1970-D silver planchet may weigh slightly more. Use a precision scale for accuracy.
5. Consult a Professional
Reputable grading services like PCGS and NGC can authenticate and grade your coin, ensuring its value is accurately determined. Coins graded as MS (Mint State) or PR (Proof) with high numerical values fetch the best prices.
