A Kennedy Half Dollar Worth $46,000? Yes — and Here’s Why
At first glance, it looks like a normal 1964 proof Kennedy half dollar.
But to elite collectors, the 1964 “Accented Hair” Proof Kennedy Half Dollar (FS-401) is one of the most desirable modern U.S. silver coins ever struck.
In perfect condition, this subtle variety has sold for up to $46,000, turning a standard proof coin into a five-figure treasure 
.
Let’s break it down step by step so you know exactly what makes this coin so special.
What Is the 1964 “Accented Hair” Kennedy Half Dollar?
The Accented Hair variety is an early proof die prototype used briefly by the U.S. Mint in 1964 before being modified.
Why This Coin Is So Valuable
Early prototype proof die
Used only for a short production run
Never released for circulation
Scarce in high-grade Deep Cameo condition
Collectors prize this variety because it represents the original design vision for the Kennedy portrait.
Key Identification Features (How to Spot One)
Step 1: Examine Kennedy’s Hair (Most Important)
Look just above Kennedy’s forehead:
Accented Hair Proof: Deep, textured hairlines with heavy detail- Normal Proof: Smoother, softer hair detail
This diagnostic feature alone separates a common proof from a rare FS-401 variety.
Step 2: Check the “I” in LIBERTY
- On genuine Accented Hair proofs, the top bar of the “I” in LIBERTY is weak or missing
- This die marker confirms the early prototype strike
Step 3: Confirm Proof-Only Characteristics
- Mint: Philadelphia (no mint mark)
Finish: Mirror-like fields with frosted devices
Found only in 1964 proof sets
