Have you ever wondered if that shiny half-dollar coin in your change could be worth far more than 50 cents? Some rare Kennedy Half Dollars have sold for staggering amounts — even rumored to be worth hundreds of millions of dollars in special cases.
This coin, first minted in 1964 to honor President John F. Kennedy after his assassination, has a rich history and surprising collectible value. While most are worth their face value, a select few are worth thousands, or even millions, due to rarity, minting errors, or historical significance.
In this guide, you’ll learn what makes certain Kennedy Half Dollars valuable, how to spot them, and where to look for one.
What Is a Kennedy Half Dollar?
The Kennedy Half Dollar is a 50-cent U.S. coin introduced by the United States Mint in 1964.
- Obverse (Front): Portrait of President John F. Kennedy.
- Reverse (Back): The presidential seal.
The original 1964 coins were made of 90% silver, making them more valuable than later versions struck from copper-nickel. Over the years, several special editions and proof sets have been released for collectors.

Why Some Kennedy Half Dollars Are Extremely Valuable
Several factors can push a coin’s value into the thousands or millions:
1. Rarity & Limited Production
Some coins, like the 1964 proof coins, were made in very small numbers, making them highly sought after.
2. Minting Errors
Errors such as double strikes, missing mint marks, or unusual finishes can skyrocket a coin’s price.
Example: A 1964 “Special Mint Set” Kennedy Half Dollar is worth thousands to millions due to its rarity.
3. Precious Metal Content
Early coins with 90% silver naturally carry higher value, especially as silver prices rise.
4. Historical Significance
Coins minted right after Kennedy’s death carry sentimental and historical appeal for collectors worldwide.
How to Spot a Valuable Kennedy Half Dollar
Here’s what to check:
- Year: 1964 coins (90% silver) are highly collectible. Years like 1970 (especially with “S” mint marks) are also rare.
- Mint Mark: Found near the date.
- D = Denver Mint
- S = San Francisco Mint
- (No mark) = Philadelphia Mint
- Minting Errors: Look for doubled letters, unusual colors, or missing details.
- Condition: Coins with minimal wear and sharp details are worth far more.
Where to Find Kennedy Half Dollars
You don’t need to be a millionaire to start the hunt:
- Bank rolls: Request half-dollar rolls and search for rare years.
- Coin dealers: Local shops may have collectible pieces.
- Online marketplaces: Sites like eBay often list rare coins (beware of counterfeits).
- Estate sales & flea markets: Hidden treasures often appear here.
How Much Can They Be Worth?

- 1964 Kennedy Half Dollar (Mint State): $10,000–$20,000
- 1970-S Proof with Error: $50,000+
