1964 Accented Hair Kennedy Half Dollar FS-401

Documented Fact FS-401 is a 1964 proof Kennedy half dollar variety with extra hair detail above the ear and most of the lower-left serif missing from the I in LIBERTY. ^{[1] [2]}

Quick Hunt

1. Confirm the coin is a 1964 proof.
2. Inspect the hair directly above Kennedy’s ear for the heavier accented pattern.
3. Check the I in LIBERTY for the missing or greatly reduced lower-left serif.
4. Require both diagnostics and compare them with certified FS-401 examples.

Primary Diagnostic

The hair is the namesake marker, but the I serif is the efficient confirmation. Wear, frost, or glare can obscure either feature, so use both.

What It Is Not

A regular 1964 proof has the later hair treatment and a normal lower-left serif on the I. Accented Hair is not a circulation-strike attribution.

Authentication Caution

Use stable magnification and several lighting angles. Match the complete marker relationship to certified examples, do not clean the coin, and obtain professional attribution before paying a substantial premium.
