(Double Struck - Close Overlap)

slab slab

This is a rare and spectacular Proof Ike Dollar Mint Error. It was struck on a clad half dollar planchet weighing 11.2 grams. Although not mentioned on the NGC insert, it is double struck with a close overlap between strikes.

There are 2 other proof Ike Dollars known that were double struck on clad half dollar planchets. They are both more dramatic and actually show a double profile of President Eisenhower's head on the obverse and parts of an extra wing on the reverse.

Proof coins are struck by technicians who hand feed the blanks into special presses. They are produced, examined and packaged using extreme quality control. It is very unusual to find major proof errors. A few broadstrikes, off-centers, double strikes (in collar) and off-metals have been known to be found in sealed proof sets. Proof errors are aggressively sought after by many error collectors.

A very small group of Proof errors recently came from a collection that was auctioned by the State of California. The U.S. Secret Service inspected and released this collection to the State of California determining that it was legal to own. The State of California then auctioned the collection and it has been dispersed since the sale.

This proof mint error survived 46 years in amazing quality and preservation. It has deep mirror surfaces with a blazing cameo portrait.
