The History of the Kennedy Half Dollar—How It All Began
After President Kennedy’s assassination in 1963, America was deeply mourned. The country decided to issue a commemorative coin to honor him. The first Kennedy Half Dollar was issued in 1964. It was the first coin at the time to feature the image of a sitting president.
Key Historical Points:
- First Edition (1964): Made of 90% silver, therefore valuable as a metal.
- From 1965 onwards: Made from a copper-nickel alloy (copper-nickel clad).
- San Francisco Mint (S): Proof and Collector Sets
- Denver (D) and Philadelphia (P): General Circulation Coins
Over time, the half dollar disappeared from general circulation and is now considered a collector’s item.
The $5.9 Million Kennedy Half Dollar—What Made It So Valuable?
This unique coin is the 1964-D Double Die Obverse Edition. This coin became the world’s most expensive Kennedy half dollar for two reasons.
1. Rare Minting Error – Double Die Obverse
On this particular coin, the obverse design was mistakenly engraved twice, resulting in:
- Double lines on the date (1964)
- Slight double impression on “IN GOD WE TRUST”
- Subtle doubling in Kennedy’s profile
Such errors are rare and highly valued by collectors.
2. Excellent Condition – PCGS Grade MS-67+
The higher the grade of a coin, the faster its value increases.
An MS-67+ grade means:
- Nearly Perfect
- No deep scratches
- Shiny, sharp details
- Extremely clean surface
This combination of error and high grade is extremely rare, which is why this coin sold for an unprecedented price in history.
What factors determine the value of a Kennedy half dollar?
If you have such coins, pay attention to the following:
1. Mint Year and Mint Mark
This is the first major factor in a coin’s value.
| Year / Mint | Feature |
|---|---|
| 1964 | 90% silver — most valuable |
| 1965–1970 | 40% silver — can still fetch good prices |
| 1971 onwards | Base metal — value depends on minting errors and condition |
2. Coin Condition (Grade)
Coin grading ranges from 1 to 70.
Higher grade = higher price.
| Grade | Value Potential |
|---|---|
| MS-60 to MS-63 | Good value but mid-level range |
| MS-64 to MS-66 | Collector grade with strong demand |
| MS-67+ | Extremely rare, can range from thousands to millions |
| Proof 70 | Ideal proof coins with premium value |
3. Minting Errors—Identifying Valuable Coins
These errors can increase the price by up to 100 times:
- Double Die Error
- Off-Center Strike
- Clipped Planchet
- Die Cracks/Cuds
- Wrong Planchet Strike
Most Valuable: Double Die Obverse (1964-D)
4. Proof Coins (Proof Sets)
Proof coins from the San Francisco Mint are considered more valuable due to their bright luster and intricate design, especially:
- 1964 Proof
- 1968-S Proof
- Special Mint Sets (SMS)
5. Silver Content
In the 1964 version:
- 90% Silver
- Good value even at today’s silver price
But collectors value its history, errors, and condition more highly.
How to Identify if Your Kennedy Half Dollar Is Valuable?
If you have a Kennedy half dollar, follow these steps:
1. Check the Mint Year and Mint Mark

Conclusion—Could you also have a hidden treasure?
The record $5.9 million sale of the Kennedy half dollar shows that sometimes a small error or rare condition can transform an ordinary coin into a valuable treasure. While most Kennedy half dollars hold a modest price, some:
- 1964 Silver Variant
- Minting Error
- High Grade

These may hold exceptional value.
If you happen to spot a rare error while browsing your old coins, it could prove to be more valuable than you expected.
