Uniface impression from a New Jersey Federal revenue $3 stamp, ca. 1798-1801. VF-20.130.4 grains. Struck over an unidentifiable and slick copper of halfpenny size, this is an impression from an early Federal embossing stamp used to mark documents after their revenue tax was paid. Apparently this die survived the era and a small number of these copper strikes were made; see an identical one in the Garrett Collection, lot 1488. As noted there, “about a half dozen specimens are believed to exist.” This is finer than the Garrett example.From the E Pluribus Unum Collection of New Jersey Coppers.
