In the world of rare coins and historical currency, few stories create as much buzz as the discovery of a valuable error coin. One such jaw-dropping tale has recently made headlines a 1964 Kennedy Half Dollar Error Coin, found in regular circulation, has reportedly sold at auction for an astonishing $11.9 million. This unexpected discovery has shocked numismatists and collectors alike.
With this extraordinary event reigniting global interest in collectible coins, especially the Kennedy Half Dollar series, let’s explore what makes these coins so special, what errors are worth a fortune, and how you can spot a rare gem in your own change.
The Beginning of the Kennedy Half Dollar
Honoring a Fallen President
The Kennedy Half Dollar was minted for the first time in 1964, just months after the tragic assassination of President John F. Kennedy in November 1963. The U.S. Mint quickly moved to honor the beloved president with a new coin, replacing the Franklin Half Dollar.
Design and Silver Content
- The obverse (front) was designed by Gilroy Roberts, featuring Kennedy’s portrait.
- The reverse (back), created by Frank Gasparro, showcases the Presidential Seal.
- The 1964 coin was composed of 90% silver and 10% copper, giving it both intrinsic metal value and historical appeal.
The 1964 release is the only Kennedy Half Dollar struck entirely in 90% silver for general circulation, making it a favorite among collectors.
Transition to Clad Coinage
Due to rising silver prices, the U.S. Mint reduced the silver content in 1965:
- 1965–1970: Coins were made with 40% silver.
- 1971 onward: All regular half dollars transitioned to copper-nickel clad, greatly reducing their metal value but still preserving collector interest in earlier issues.

The coin was authenticated by PCGS (Professional Coin Grading Service) and sold through a private auction, setting a new record for the most expensive Kennedy Half Dollar ever sold. The buyer remains anonymous but is rumored to be a high-profile international collector.
How to Identify a Valuable Kennedy Half Dollar
So how can you tell if the half dollar in your drawer is worth a few cents or a few million?
1. Check the Date
- 1964 is the golden year. Any coin from this year deserves a closer inspection, especially for errors or proof-like qualities.
2. Examine the Mint Mark
- Look for mint marks like “D” (Denver) or “S” (San Francisco).
- Certain combinations, like 1964-D, are known for rare varieties.
3. Look for Errors
- Check for doubling of letters, off-center strikes, or missing layers.
- Use a magnifying glass or take the coin to a professional grader if unsure.
4. Inspect the Edge
- Silver coins from 1964 have a solid, silver-colored edge.
- Coins after 1971 show copper streaks along the edge due to their clad composition.
Where to Find Rare Kennedy Half Dollars
Even though most valuable coins are found in collections or auctions, you might still come across a treasure if you know where to look.

Requesting half dollar rolls from local banks is a popular method called coin roll hunting. While it takes patience, some hunters have reported finding silver and error coins in circulation.

3. Online Auctions and Dealers
