Newly discovered 1867-S Half Eagle also shatters previous auction record in $10.665 million U.S. coins event; 1934 $10,000 Federal Reserve Note Leads $8.7 million U.S. currency auction.
The 1887/6 overdate variety is popular both as an error and as the only issue from that year within the Proof Three Cent Nickel Series. It is assumed that there were left over dies from the previous year that were reused. There are actually two varieties for this overdate, one of which is strong and the other, weak (describing how easily the six is seen). The weak overdate is scarce with the strong overdate significantly rarer and more desirable.
Obverse Description
A Romanesque Liberty is portrayed facing left with LIBERTY emblazoned on her crown. UNITED STATES OF AMERICA appears on the periphery with the date at the bottom.
Reverse Description
The roman numeral III is centered in the design surrounded by a large wreath tied with a bow at the bottom. This design is one of few American coins without wording on one of the sides.
