1973-S Proof Silver Ike Dollar
NGC PF 68 Cameo
This proof Ike Dollar was multistruck and broadstruck on a SILVER planchet. The first strike was normal with full reeding. The subsequent strikes were broadstruck out of the collar. There is visible design of the first strike, including a double profile and LIBERTY
on the obverse, and a double UNITED STATES OF AMERICA
and eagle's 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.
