1877-S Liberty Head Eagle. AU-55 (NGC). Much of the semi-prooflike finish remains on both sides of this vivid straw-gold example. The 1877-S is a low mintage (17,000 pieces) eagle that circulated extensively in an era when gold coins enjoyed strong commercial demand on the West Cost. Problem free survivors such as this are always in demand irrespective of numeric grade, although with Mint State coins all but unknown Choice AUs are particularly attractive to advanced gold enthusiasts.
