Known Errors

Accented Hair Variety

Early proof dies show extra detail in Kennedy's hair above the ear, with a more defined hairline. This is technically a die variety but commands strong premiums.

How to check: Compare the hair strands above Kennedy's ear to a normal 1964 proof. The accented hair shows sharper, more distinct lines.

$50 - $500+

Doubled Die Reverse

Notable doubling on UNITED STATES OF AMERICA and the eagle's tail feathers.

How to check: Examine the reverse lettering with magnification. Look for shelf-like doubling on E PLURIBUS UNUM.

$30 - $200

Heavy Die Polish Lines

Excessive polishing of dies created visible raised lines across the coin's surface.

How to check: Look for fine parallel raised lines running across the fields or design elements.

$10 - $75

Repunched Mint Mark

The D mint mark shows evidence of being punched into the die more than once.

How to check: Examine the D mint mark under magnification for any secondary impression or shadow.
