Proof 1970-S Lincoln Cent
Multi-Struck on Dime Planchet

NGC PF 66 Cameo


This 1970-S Proof Lincoln Cent was struck multiple times on a clad dime planchet weighing 2.2 grams. The cameo contrast with proof mirror surfaces gives this proof off-metal great eye appeal.

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.
