1973-S Proof Clad Ike Dollar Double Struck On A 50¢ Planchet
This is one of the most spectacular Proof Ike Dollar Mint Errors of all time. Not only is it a spectacular double struck, it is also struck on a clad half dollar planchet.
There are 2 proof Ike Dollars known that were double struck on clad half dollar planchets. The other example known shows the top of President Eisenhower's head underneath the second strike. This PCGS Proof 66 mint error dramatically shows 2 full profiles on the obverse, while the reverse shows 2 moons and part of a second eagle.
This proof mint error is the ultimate modern major mint error on the highest denomination and has survived 46 years in amazing quality and preservation. It has light original toning over flawless proof fields.
Below is another fantastic proof Ike Dollar major mint error that I recently sold and is featured in my NLG award winning book, World's Greatest Mint Errors.
