1877-CC Liberty Head Half Eagle. EF-45 (PCGS).Lovely olive-gold patina to both sides, the surfaces also revealing lighter medium gold outlines to many of the devices that is associated with remaining luster. Sharply defined overall with an uncommonly smooth appearance for a lightly circulated gold coin from this fabled frontier era coinage facility. The 1877-CC is one in a lineup of rare Carson City Mint half eagles. The mintage is limited at 8,680 pieces, Rusty Goe estimating that only 150 to 195 coins are extant in his cataloging for our August 2012 sale of the Battle Born Collection.
