There were just 6,600 examples struck and this is a numismatically significant issue as the first San Francisco issue of this denomination. The 1855-S is the rarest of the four available San Francisco Three Dollar gold pieces and it is seldom seen in affordable collector grades, especially with natural color and surfaces. This choice, fresh example shows lovely deep natural amber-russet color atop smooth, evenly worn surfaces. There are a few small marks in front of the O in OF but the overall eye appeal of this coin is far above average for the date and grade. This is one of just two examples of this date in EF40 to have ever received approval from CAC (six finer have been recorded as well). The other example, ex Heritage 4/10: 3557, sold for $2,645. I bought that coin out of the aforementioned sale and I think the present example is nicer. This is a great historic branch mint piece for the new collector.
