Proof 1972-S Silver Ike Dollar
Improper Obverse Die Alignment

NGC PF 64 Cameo


Coins struck from mis-aligned obverse dies are not rare or expensive but in proof they are very rare and normally only slightly mis-aligned on the obverse. This 1972-S Proof Silver Ike Dollar was dramatically struck by an obverse die that was mis-aligned 15% off-center. The mis-alignment effected the pressure of the dies striking the planchet leaving areas on both sides that were not struck by the dies.

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 unique discovery of a proof Ike Dollar struck by a mis-aligned obverse die should stir excitement of collectors of Eisenhower Dollars and Major Mint Errors.
