The quality of strike seen on 1869-S Double Eagles is not very good. The obverse shows an unusual somewhat concave appearance. This results in flat areas on the hair of Liberty as well as on the stars. Many of the stars show extra outlines where an engraver attempted to strengthen them. As this work was done inside the mint, it is considered a diagnostic characteristic and does not affect a coin’s value. 

Surface Quality, Luster, Coloration, and Eye Appeal

As on so many of the San Francisco Double Eagles produced during this era, the surfaces on the typical 1869-S are liberally abraded. The luster is subdued and slightly grainy with a deep, frosty texture. Uncleaned pieces will show a range of colors which include rose-green, deeper green-gold, and orange-gold hues. The level of eye appeal seen on most examples of this date is not very high. Coins which are attractive, or which show a good strike are scarce and they carry strong premiums.
