1873-CC Seated Liberty Half. Scarce coin with a mintage of 214,560. This is the large CC variety.
This article - http://www.seateddimevarieties.com/95-E-GobrechtVolume8,Issue12.pdf - contains more information about the Berlinghof pedigree. Apparently a single collector/dealer accumulated a hoard of some 350 coins of this date and mintmark - almost half of the total amount estimated to exist, according to the article.
Shipping and insurance included.
