(1973)-S Proof Ike Dollar
Double Struck on Cent Planchet



This is one of the most spectacular Proof Ike Dollar Mint Errors known today. Not only is it a spectacular double struck, it is also struck on a copper cent planchet weighing 3.1 grams and is unique to date.

Although there are a few proof Ike Dollars struck on Cent planchets known, this is the only one that is double struck and shows incredible detail from the original strike. The obverse shows 2 portraits with the date from the first strike and the reverse shows part of the eagle from the first strike as well as other details.

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 is the ultimate modern major mint error on the highest denomination and has survived 46 years in amazing quality and preservation. It has deep mirror surfaces with virtually all of the original red showing. This unique proof major mint error belongs in a collection of Eisenhower Dollars or major mint errors.
