1878-S Liberty Head Half Eagle. MS-62 (PCGS). CAC. A frosty and smartly impressed MS-62 example offers vivid color in bold golden-rose. Half eagle production at the San Francisco Mint increased markedly in 1878 with a mintage of 144,700 pieces. This was achieved in anticipation of the government-mandated return to parity between gold coinage and paper currency set for January 1, 1879. Unfortunately for todays collectors, this increase in mintage did not result in a generous supply of Mint State survivors. Most examples saw extensive commercial use, and even coins at the MS-60 to MS-61 level are elusive. This is one of the finest 1878-S fives that we have had the privilege of bringing to auction in recent years, and it is sure to fetch a strong price. From the Fairmont Collection-Hendricks Set.
