1874-S Trade Dollar. Unc Details--Chopmarked (NGC).Brilliant apart from a few wisps of olive-russet here and there around the peripheries, this pleasing example also offers sharp striking detail and full satin luster. Two neatly executed shops are noted: one on the obverse above the digit 7 in the date and another, more prominent, in the lower left reverse field. A high mintage (2,549,000 circulation strikes) issue that saw widespread export to the Orient, the 1874-S is one of the more frequently encountered trade dollars with chopmarks.
