NGC 1948-1963 Franklin half dollar struck 55% off-center on a silver quarter blank. The coin both an an off-center strike and is struck on a silver quarter blank. An amazing wrong planchet and off-center combination.
The error occurred when the 25c blank which was intended for striking into a silver Washington quarter, was instead fed into a press striking Franklin half dollars. It was not fed entirely between the dies, and so was struck off-center.
An incredibly rare major mint error Franklin half error, with perhaps 3 or 4 known of this combination for the Franklin half series. Find another!
