Ever dreamt of finding treasure in your pocket change? The 1970-D Kennedy Half Dollar error coin might be just that—a hidden gem worth up to $350,000. With a rare minting mistake and a fascinating backstory, this coin has become the holy grail for collectors and casual hobbyists alike. If you’ve got a Kennedy Half Dollar from 1970, it’s time to take a closer look. This guide will walk you through everything you need to know—how to identify this rare error, why it’s so valuable, and how to get it professionally graded.
History
The Kennedy Half Dollar was introduced in 1964 as a tribute to President John F. Kennedy following his tragic assassination. Americans embraced it instantly, and it became a symbol of hope and remembrance. Fast forward to 1970, and the half dollar was no longer issued for general circulation. Instead, it was minted mainly for collectors, with a limited number struck in Denver using 40% silver.
This specific year and mint location—1970 in Denver—gave rise to one of the most mysterious and valuable minting errors in U.S. coinage history: a Kennedy Half Dollar missing its “D” mintmark.
Error
So, what’s the deal with the missing mintmark? A normal 1970-D coin should have a small “D” on the reverse, below the eagle’s talons. But due to an oversight during production, a few coins were struck without this mark. These no-mintmark coins slipped through unnoticed—until keen-eyed collectors discovered the mistake.
This tiny detail turns a regular collector’s coin into a rare find that could sell for hundreds of thousands of dollars. Why? Because collectors crave imperfections—they’re like rare misprints in stamps or books.
Rarity
How rare is it? Very. Experts believe only a handful of these error coins exist in uncirculated condition. Some estimates suggest fewer than 20 have been confirmed. The exact number is unknown, making them even more appealing to collectors.
The rarity, combined with the Kennedy Half Dollar’s iconic status and its 40% silver content, makes this coin a trifecta of collector value: historic, flawed, and valuable.
Grading
Here’s the catch—condition matters a lot. A coin with wear and scratches won’t fetch as much as one in pristine shape. Coins are graded on a scale from 1 to 70, and you’ll need a score of 65 or higher (known as MS-65+) to get into the big-money range. The rarest examples, graded MS-67 or better, have sold for over $350,000.
To find out your coin’s grade, submit it to professional services like PCGS or NGC. These companies verify authenticity, assess condition, and seal your coin in a tamper-proof holder—making it more appealing to buyers.
Spotting
Think you might have one of these elusive coins? Here’s a quick checklist to help you identify it:
| Step | What to Do |

| 1 | Check the reverse side under the eagle’s talons |
| 2 | Look for the missing “D” mintmark |

Value
Even if your coin isn’t worth $350,000, don’t be discouraged. Lower-grade examples of the 1970-D error coin can still sell for thousands. Here’s a rough value guide:
| Grade | Estimated Value |
|---|---|
| MS-67 | $350,000+ |
| MS-65 | $10,000 – $25,000 |
| XF-45 | $2,000 – $5,000 |
| VG-8 | $500 – $1,000 |
