Just certified by CAC and unknown to the numismatic community, this Eisenhower Dollar mint error is unique. It has a brockage from an Eisenhower Dollar that was struck on a Dime planchet. Since the Eisenhower Dollar struck on a Dime planchet was very thin, the pressure from the Eisenhower Dollar dies expanded the diameter as it was struck into the Eisenhower Dollar planchet. This is an incredibly rare sequence of events.

Somewhere out there is the other half of this mated pair. It would be an Eisenhower Dollar Struck on 10¢ Planchet. The obverse would have an expanded and distorted portrait of President Eisenhower.

In my opinion, this Eisenhower Dollar is as struck and in original condition with film on both sides. The weakness of IN GOD WE TRUST on the obverse and UNITED STATES on the reverse are due to the lack of die pressure since there was another coin in the collar.

This unique Eisenhower Dollar major mint error belongs in a collection of Eisenhower Dollar errors or unique errors.
