||1872 50C PR66 Cameo NGC. Ex: "Col." E.H.R. Green. This brightly mirrored proof striking would fit well into the finest 19th century type set. The mirrored fields are unfathomably deep and the devices are thickly frosted. Each side is primarily brilliant with marginal toning in deeper russet and cobalt-blue shadings. Few of the 950 proofs struck can compare to the exceptional preservation and compelling appearance of this piece. Census: 10 in 66 Cameo, 3 finer (9/13). Ex: "Colonel" E.H.R. Green; Green Estate; Partnership of Eric P. Newman / B.G. Johnson d.b.a. St. Louis Stamp & Coin Co.; Eric P. Newman @ $8.50; Eric P. Newman Numismatic Education Society.
