Kennedy Half Dollar
The Kennedy Half Dollar series began in 1964, one year after the assassination of President John F. Kennedy. It was introduced as a tribute to the late president and became an instant hit among Americans, symbolizing both national mourning and hope for the future.
By 1970, half dollars were no longer released into general circulation but were instead minted primarily for collector sets. The 1970-D Kennedy Half Dollar is especially significant because it was the last half dollar made with 40% silver, making it a key piece in U.S. coin history.
Valuable
The value of the 1970-D Kennedy Half Dollar lies in its rarity and unique minting error. Only a small number of these coins were ever struck without the “D” mintmark, making them incredibly rare. Here’s why collectors are willing to pay top dollar for this coin:
Rarity
The missing “D” mintmark error was an unintentional mistake, making this coin highly desirable. Experts estimate that fewer than 20 uncirculated examples exist, while the total number of surviving error coins remains unknown but is believed to be very small.

Condition and Grading
Coins in mint state (MS-65 or higher) fetch the highest prices. For example:
- An MS-67 example of the 1970-D error coin could sell for $350,000 or more.

How to Identify
If you suspect you might have one of these rare coins, follow these steps to determine its authenticity.
Step 1
A standard 1970-D Kennedy Half Dollar should have a “D” mintmark below the eagle’s talons on the reverse. If this mark is missing, you could have a rare error coin.
Step 2
Check for signs of wear, scratches, or discoloration. The more pristine the coin, the higher its potential value.
Step 3
If you’re unsure about the mintmark area, use a magnifying glass or coin loupe to inspect the details more closely.
Step 4
To verify the authenticity and condition of your coin, send it to a reputable grading service such as:
- PCGS (Professional Coin Grading Service)
- NGC (Numismatic Guaranty Corporation)
Grading provides official certification, assigns a grade to your coin, and helps establish its market value.
