NGC Proof-64 Brown (illustrated above).  Ex - Superior Galleries' "Pre-Long Beach Sale", October 1-3, 2000, Lot 4417, where it was described as follows:  "Judd-487, Pollock-576. Copper. Plain Edge. Head of Abraham Lincoln facing left. Brown, with tinges of red at the lettering; an old fingerprint in the reverse field. The Act of May 17, 1866 prohibited further issue of paper currency in denominations less than ten cents and provided for the issue of nickel five cent pieces. As a result, a large number of Patterns were made for this denomination. The obverse designs include a shield copied from that used on the two cent piece, different designs of the head of Washington and one of the head of the martyred Lincoln, who had been assassinated in April 1865. These were combined with a variety of reverses."
