Known Errors

Doubled Die Reverse (DDR)

Strong doubling visible on UNITED STATES OF AMERICA and HALF DOLLAR on the reverse. One of the most dramatic doubled dies in the Kennedy series.

How to check: Flip the coin to the reverse and examine the lettering with a loupe. Look for clear split or shelf doubling on UNITED STATES.

$50 - $400+

Die Clash

Obverse and reverse dies struck each other without a coin between them, transferring ghost impressions.

How to check: Look for faint outlines of the reverse design on the obverse fields, or vice versa.

$5 - $50

Broadstrike

The coin was struck outside the collar die, causing it to spread wider than normal without the reeded edge.

How to check: Measure the diameter. A normal Kennedy half is 30.6mm. Broadstrikes will be noticeably wider with a smooth edge.

$30 - $200
