1861 Clark, Gruber & Co. $2.50 Die Trial. K-9a, var. Gilt Copper. Reeded Edge. Unc Details--Improperly Cleaned (NCS).Bright golden patina throughout, both sides are sharply to fully defined throughout the design. Wispy hairlines and a somewhat matte-like texture explain the NCS qualifier, but there are no sizeable or otherwise singularly distracting marks. While a small number of copper die trials of the 1861 Clark, Gruber & Co. $2.50 have passed through our hands over the years, only a few of those have been gilt, as here. A handsome coin for the assigned grade that is worthy of serious bidder consideration.From the Collection of Samuel J. Berngard.
