This is one of two known 1972-S SILVER Eisenhower Dollars struck on Half Dollar Planchets. The other 5-6 known are 1973-S CLAD Eisenhower Dollars.

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.

Recently, the only other example known, certified by PCGS, sold in a GreatCollections auction for $17,437.50 (Oct 17, 2021, GC Item ID: 1053931).
