1850-O Liberty Seated Half Dollar. WB-Unlisted. MS-65 (NGC).This handsome piece is warmly and originally toned, direct light angles calling forth vivid undertones of red, blue and gold. The strike is sharp to full throughout, and uncommonly so by the standards of the issuing mint. Satiny in finish with a smooth texture, it is little wonder that this coin ranks among the finest certified survivors from a mintage of 2,456,000 pieces. The 1850-O is one of the more frequently encountered Liberty Seated half dollars from the 1840s and early 1850s, but the vast majority of survivors are worn to one degree or another, indicative of the heavy circulation that this issue experienced. Mint State survivors of even marginal quality are scarce, while as a Gem the coin offered here is nothing short of rare.Ex Colonel E.H.R. Green; Green estate; Partnership of Eric P.
