What Is a Kennedy Half Dollar?
The Kennedy Half Dollar is a U.S. 50-cent coin first issued in 1964, shortly after President Kennedy’s assassination in 1963. Designed by Gilroy Roberts (front) and Frank Gasparro (back), it features Kennedy’s portrait on the front (obverse) and the Presidential Seal on the back (reverse). Early coins (1964) were made of 90% silver, but from 1965 to 1970, they had 40% silver, and after 1971, they switched to copper-nickel. Most are worth 50 cents, but rare errors, low-mintage years, or special finishes make some highly valuable.
Why Are Some Kennedy Half Dollars So Valuable?
The value of a Kennedy Half Dollar depends on:
- Minting Errors: Mistakes like doubled designs or missing mint marks.
- Rarity: Low-mintage coins or special editions, like the 1964 SMS.
- Condition: Uncirculated coins graded MS65–MS70 by PCGS or NGC fetch higher prices.
- Silver Content: 1964 coins with 90% silver have higher intrinsic value.
The 1964 SMS, with only about 12 known examples, is the rarest and most valuable, potentially worth $900,000 in top condition due to its unique satin finish and sharp details.
Rare Kennedy Half Dollar Varieties to Look For
Here are the top Kennedy Half Dollars that could make you rich:
1964 Special Mint Set (SMS) Half Dollar
The 1964 SMS is the rarest Kennedy Half Dollar, with only about 12 known. These coins have a satin-like finish, sharp details, and die-polishing lines, unlike regular coins. One graded SP68 sold for $156,000 in 2019, and experts estimate a pristine SP69 could reach $900,000.
1964 Accented Hair Proof
This early 1964 proof has extra hair details above Kennedy’s ear and a missing serif on the “I” in LIBERTY. Less than 5% of 1964 proofs have this design, making them rare. A PF68 Deep Cameo sold for $46,800 in 2024.
1970-D Half Dollar
Minted only for collector sets, the 1970-D has 40% silver and a low mintage of 2.1 million. Uncirculated examples can fetch $50–$500, with one MS67 selling for $13,000 in 2018.
1968-S Proof Deep Cameo
The 1968-S proof, minted in San Francisco, is superior in quality to earlier proofs. A PF70 Deep Cameo sold for $24,000 in 2023 due to its flawless strike and mirror-like finish.
How to Spot a Valuable Kennedy Half Dollar
To find a rare half dollar, check these details:
- Year: Focus on 1964, 1968, or 1970. Look for “1964” or “1970-D” below Kennedy’s neck.
- Mint Mark: Check below Kennedy’s neck for “D” (Denver), “S” (San Francisco), or no mark (Philadelphia). Missing marks on proofs are key.
- Finish: SMS coins have a satin look; proofs have a mirror-like shine.
- Errors: Look for doubled text, extra hair, or unusual strikes with a magnifying glass.
- Condition: Uncirculated coins with no wear are worth more.
Compare your coin to images on PCGS or NGC. Avoid cleaning, as it reduces value.

Why Are These Coins Still in Circulation?
Kennedy Half Dollars are rarely used in everyday transactions due to hoarding after their 1964 debut, especially for their silver content. Errors like the 1964 SMS or 1970-D slipped into circulation through mint sets or estate sales. Coin roll hunting, popularized on platforms like X, keeps collectors searching bank rolls and change jars for these treasures in 2025.
