(1972)-S Proof Ike Dollar
Double Struck on Cent Planchet
NGC PF 66 RD CAMEO
1 of 2 Known
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 one of two known.
This proof mint error is the ultimate modern major mint error on the highest denomination and has survived 50 years in amazing quality and preservation. It has deep mirror surfaces with virtually all of the original red showing. The obverse and reverse show considerable detail from both strikes. This proof major mint error belongs in a collection of Eisenhower Dollars or major mint errors.
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.
