Only 15,200 examples were struck and this is one of my favorite "sleeper" dates in the entire San Francisco quarter eagle series. The 1859-S is very scarce in the higher AU grades and it is very rare in Uncirculated. The beauty of this date in AU58 is that it is affordable and there is a large price jump once the Mint State grades are reached. This piece is bright and quite lustrous with a good strike and just a few small marks in the fields. At less than $3,000 this is a really good value for the collector of undervalued United States gold coins.
