The Kennedy half dollar may look like a typical 50¢ coin, but a small number of rare varieties, especially from 1964, are valued at up to $900,000.
These collector-grade coins offer a surprising chance for massive returns—let’s explore the facts, figures, and details that distinguish these numismatic treasures.
What Makes Some Kennedy Halves So Valuable?
1. 1964 Special Mint Set (SMS) Variety
- Only about a dozen known examples exist.
- Features a satin‑finish, mirror‑like surface, ultra‑sharp strike and deep detail lines.
- No mint mark, unlike standard circulation versions.
- Recently, rare pieces have fetched prices as high as $900,000 at private auctions.
- Even earlier SMS examples sold in 2019 for $108,000 (SP67 grade) and $156,000 (SP68 grade).
2. 1964 Accented Hair Proof Variety
- Identified by extra hair lines between the part and ear, and a missing serif on the “I” in LIBERTY.
- Usually issued in proof sets; these are extremely rare.
- High-grade specimens (e.g. PR69 cameo) have sold for around $45,600; some listings suggest up to $19,975 depending on condition and cameo grade.
3. Other High-End Sales
- A private sale reportedly reached $5.9 million for one SMS specimen—possibly the same class of 1964 SMS coins.
- Anecdotal reports describe $3.2 million-valued Kennedy half-dollars found in change at small businesse .

How to Identify a Potential $900K Coin
- Date & mint mark: A 1964 coin without a mint mark (SMS type) is key.
- Surface finish: Look for a satin‑smooth mirror finish, not typical of circulation strikes.
- Sharpness & strike: Ultra‑crisp detail in JFK’s hair, jawline and presidential seal.
- Accented Hair proof: Check for extra hair lines above the ear and serif irregularity on “I” in LIBERTY.
Why the $900K Figures Sound Reliable
- Coverage by credible outlets and coin‑collecting forums confirms ongoing $900K private sales of top‑quality 1964 SMS specimens.
- Graded coins (SP67/68, PR69) are trading in the six‑figure range, with documented auction results between $108K and $156K .
- Rare one‑off finds—though uncommon—support multi‑million valuations for previously unknown SMS coins.
What Might Disqualify Your Coin
- Circulated 1964 halves with wear, toning or damage typically offer only silver melt value (~$10–$20).
- Proof versions without Accented Hair, or standard proof/uncirculated coins, usually value between $75–$1,000 depending on grade.
- Later years (1965‑1970, clad issues, modern proofs) generally hold modest collector premiums only.
While most Kennedy half dollars aren’t worth more than their face value or silver content, a select few 1964 SMS and Accented Hair proof varieties have generated auction and private sales in the six‑figure to near‑million‑dollar range.
With only a handful of SMS coins known, and expert‐graded pieces fetching up to $156K, private deals allegedly reaching $900K or more are real possibilities—for exceptionally rare examples. If you believe you hold one, professional certification is essential.
FAQs
Could my regular 1964 Kennedy half be worth $900,000?
If it’s a Special Mint Set (SMS) 1964 variety with a satin finish, no mint mark, and superb strike, yes—it could be in that rare high-end category.
What’s the difference between Accented Hair and SMS coins?
The Accented Hair is a proof variety defined by extra hair lines and die anomalies; SMS coins refer to satin-finish Special Mint Set strikes distinguished by finish and strike accuracy, and are far rarer.
What should I do if I think I have one of these?
Keep the coin untouched, photograph it, and seek professional grading from PCGS or NGC. Certified high grades (SP67+, PR69+) vastly increase authenticity and value.
