History of the Kennedy Half Dollar
The Kennedy Half Dollar was first issued in 1964 to honor President John F. Kennedy after his tragic assassination. The coin was an instant hit, symbolizing hope and remembrance. However, by 1970, the U.S. Mint ceased issuing half dollars for general circulation, striking them primarily for collectors. That year, the Denver Mint produced a limited number of these coins with 40% silver content.
Among them, a rare minting anomaly occurred-a small number of 1970-D Kennedy Half Dollars were struck without the “D” mintmark, making them one of the most valuable mint errors ever discovered.
The Rare Error: Missing Mintmark
What makes this coin so special? Normally, a 1970-D Kennedy Half Dollar should have a small “D” mintmark below the eagle’s talons on the reverse. However, a few were mistakenly struck without this mark. These error coins remained unnoticed until keen-eyed collectors discovered them.
Why does this matter? Because collectors prize minting errors, much like rare misprints in books or stamps. This minor oversight transforms an already collectible coin into a numismatic treasure that can fetch hundreds of thousands of dollars at auction.
Rarity and Demand
Just how rare is this error coin? Extremely. Experts estimate that fewer than 20 examples exist in uncirculated condition, though the exact number remains unknown. The combination of rarity, historical significance, and 40% silver composition makes this coin an ultimate collector’s item.
How Coin Grading Affects Value
Condition plays a crucial role in determining a coin’s worth. Coins are graded on a 1 to 70 scale, with higher numbers indicating better preservation. To reach the highest values, a 1970-D error coin needs to grade MS-65 or higher. In top condition (MS-67 or better), these coins have been known to sell for over $350,000.
To authenticate and assess the condition of your coin, submit it to professional grading services like PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Company). These companies verify authenticity and assign a grade, sealing the coin in a secure holder for protection and added value.
